Pandemic Awareness/Preparation

Nurses COVID

Updated:   Published

It has been my own personal project to follow H5N1 for the last 3 years simply because it interests me. Attracted to this type of information like a magnet, I've been watching this relatively new influenza virus to see where it will go, how it will change itself, and possibly change our world. I have followed its country by country outbreaks, and watched for the important viral mutations such drug resistance or changes that allowed it to more specifically target mammals.

Keeping in mind at all times that we will be cleared impacted as HCW, as well as being members of our communities, and having families of our own to care for, I wanted to start the new year by opening a single focused pandemic thread that would also look at what we are doing nationally to prepare for a future pandemic. Is this the virus to spark the next pandemic? No one can answer that question. We can look back at the past to the last few pandemics, and in particular to the most devastating one in 1918, and extrapolate useful information about them, but we can not predict the future. We can only make comparisons with our situation now, and learn what worked to lessen morbidity and mortality in those past events. And, we can look at those other viruses, and compare them with what we are seeing now. For example, H5N1 is a Type A virus. We know that all pandemics are caused by Type A viruses. It is also an avian virus. The deadly 1918 virus, H1N1 was also an avian virus.

For this thread, as in the previous threads, I will be making use of news sources, scientific studies, govt bulletins such as the MMR, as well as flu forums and blogs devoted to this subject for my sources. Because press information, particularly the foreign press, is not always available for later access when I am looking back to check recent historical information, the use of these blogs and forums are important because archived information quoting the media and all other sources is always fully and easily available there with no worries about information disappearing or no longer being available. They also fully document their sources or I would not be using them.

With this link from Avian Flu Diary, a well researched source that I highly recommend, we can read the words of outgoing HHS Secretary Leavitt on our state of preparedness. Leavitt has done an admirable job during his tenure, but admits that there is much left to do.

A scant 33 months ago, I sent my first message about a race that HHS had just begun. As I said then, it was a race against a fast-moving virulent virus with the potential to cause an influenza pandemic. Since then, we have mobilized experts and resources across the country and around the world. I now send you this final message, as I look back at the unprecedented progress we have made in energizing a national pandemic influenza preparedness movement in those 33 months.

Today, many people mistakenly think influenza pandemics are a thing of the past, but influenza has struck hard in the era of modern medicine – much harder than most people realize. And it will strike again. Pandemics are hard things to talk about. When one discusses them in advance, it sounds alarmist. After a pandemic starts, no matter how much preparation has been done, it will be inadequate.

Bird flu scare: Chandigarh keeps a watch on winged visitors

http://timesofindia.indiatimes.com/Cities/Chandigarh_monitors_migratory_birds/articleshow/3992997.cms

http://en.wikipedia.org/wiki/Chandigarh

This beautiful area in northern India is on alert. Better to be prepared than surprised.

CHANDIGARH: As this city plays host to around 15,000 migratory birds which are here for the winter, the administration is watching out for signs of danger - in the form of bird flu that hit some Indian states last year.

"The common symptoms are that the bird starts to stay at secluded places away from the flock, it stops flying, there is an unusual bending of the neck, secretion from eyes and it does not eat anything."

Grebes, geese, shelducks, marsh ducks, diving ducks, rails, coots, stilts, hill kingfisher, mallard, pintail, Siberian ducks, pochards, cranes, storks and sandpipers are some of the migratory birds that come visiting the city every year. They come from Siberia, Central Asia, China, Afghanistan and the upper Himalayas.

A recent joint study by US and Japanese scientists found strong genetic evidence that wild migratory birds are the most important carriers of avian influenza viruses from continent to continent.

Rohit Ruhella, an environmentalist based here, said: "Infected birds carry influenza virus in their saliva, nasal secretions and excretions. Other birds get infected when they come in contact with these contaminated secretions or excretions or with the surfaces that are contaminated.

"Scientists all over the world are convinced that migratory birds are carrying the H5N1 virus in its highly pathogenic form. They carry it over long distances, and many times spread the virus among poultry birds that come in their way."

Most of the migratory birds here, around 14,000, have made their winter homes in Chandigarh's famous Sukhna Lake and the 190-odd ponds and swamps around, which together form the Sukhna Wildlife Sanctuary, declared a protected national wetland.

Indonesia

This case is not confirmed, and even if positive might never be due to the ongoing

censorship in Indonesia.

http://www.recombinomics.com/News/01170901/H5N1_Tangerang_Cluster_2009.html

...The mother (43F) was transferred to an infectious disease hospital after failing to respond to treatment. She died within hours of admittance. The comment by the attending physician is likely based on a infleunza A positive rapid test, but there has been no official confirmation. This is a common pattern for H5N1 cases and clusters in Indonesia.

Moreover, three family members also had symptoms, but recovered. The likelihood that they will test positive is near zero. Indonesia has had a case fatality rate near 80%, which it has had since 2005. The high rate is due in part to testing / reporting issues. The MOH has already commented on a lowering of cases due to Tamiflu treatment. However, Tamiflu treatment should lower the case fatality rate, not the number of confirmed cases unless there was frequent human to human transmission, treatment generated a false negative, or both. Since there are dozens of examples of both, including the cluster described above, the artificial lowing of confirmed cases and clusters, the true extent of human H5N1 in Indonesia remains unclear.

China

http://crofsblogs.typepad.com/h5n1/2009/01/china-confirmed-human-h5n1-case-in-shanxi-province.html

The Centre for Health Protection (CHP) of the Department of Health received notification from Ministry of Health (MoH) tonight (January 17) concerning a confirmed human case of avian influenza H5N1.

A CHP spokesman said the patient was a two-year-old. She developed symptoms on January 7 in Hunan and was brought to Shanxi for medical treatment on January 11. She is now in critical condition.

Laboratory tests on the patient's specimen by Chinese Centre for Diseases Control and Prevention yielded positive to H5N1.

http://www.recombinomics.com/News/01180901/H5N1_Hunan_Concerns.html

She was infected right after the patient in Beijing died, who was infected a couple weeks after the outbreaks Jiangsu. All three incidents (see updated map) involved H5N1 confirmed hosts in the absence of dead poultry.

The outbreaks in Jiangsu were detected during routine surveillance. As noted in the OIE report, there were no dead birds.

Clade 7 is cause for concern because it has caused at least one human case previously and was in asymptomatic birds in Jiangsu. Moreover, it has caused problems previously in vaccinated flocks. The genetic differences between clade 7 and clade 1 or 2 can produce vaccine mismatches which generate asymptomatic birds which shed H5N1 that can infect other birds and humans. This creates conditions for silent transmission in birds and cases that have no clear linkage to dying poultry.

China has not filed any OIE reports since the Jiangsu outbreak in December, suggesting H5N1 was not detected in poultry culled in the Beijing area. Detecting H5N1 in asymptomatic birds is difficult, so the absence of H5N1 positive birds does not necessarily signal the absence of H5N1.

The widespread detection of H5N1 in China in the absence of dead or dying poultry is cause for concern.

Absolutely, good catch, gentlegiver. Thanks for sharing the information.

This new case is of concern because there was no indication of any contact with sick birds. This could be indicative that H5N1 is spreading "silently" in infected but asymptomatic birds.

Here is what virologist, Dr. Henry Niman has to say about this. He notes a report made to OIE, [the animal version of the WHO] about the culling of asymptomatic poultry. The report does not say that there any fatal cases in those birds, indicating that they were only culled because they were positive for the virus not because they were sick. Then gravely ill humans cases started occurring, and an HCW started showing symptoms, (probably infected by the first patient, the 19 year old female in Beijing).

It used to be that when poultry start dying, people had a good indication that a danger was present. But, there was no clear signal this time, and that is very alarming. Sick birds in China are not serving the role of sentinels to detect the virus.

http://www.recombinomics.com/News/01180903/H5N1_Clade7_China.html

...comments are from the OIE report submitted by China for the two H5N1 outbreaks in Jiangsu, China (see updated map). Although 376,998 birds were culled, there were no fatalities listed in the December 26 report because the birds were asymptomatically infected. This raised concerns that similar infections at other farms led to the silent spread of clade 7, which was the clade in Jiangsu...

The Jiangsu outbreak was followed by the confirmed case (19F) in Beijing, who had purchased and gutted ducks in Hebei and developed symptoms on Dec 24. It is unlikely that these birds had symptoms, and a survey of birds near Beijing failed to identify dead or dying poultry. However, a health care worker in Beijing did develop symptoms, raising concerns of increased efficiency of transmission to humans.

The Beijing case(s) were followed by the fatality in Shandong (27F), who developed symptoms on January 5. The possible exposure has not been disclosed.

These two cases were followed by the case (2F) in Hunan, who is in critical condition in Shanxi. Surveys of markets in Hunan and Shanxi failed to identify dead or dying poultry.

Thus, there has been no linkage of any of the three confirmed H5N1 to dead or dying poultry. However, vaccination of poultry with a poorly matched vaccine would yield asymptomatic birds shedding H5N1 virus, which would facilitate spread in immunized birds that could lead to fatal human infections.

another death in china

http://crofsblogs.typepad.com/h5n1/2009/01/china-teenager-dies-from-h5n1.html

http://www.transworldnews.com/newsstory.aspx?id=73643&cat=0

a 16-year-old male student died of bird flu in central china's hunan province tuesday morning, the third death caused by avian influenza in the country in the new year, provincial health authorities reported.

the student, surnamed wu, died at about 8:10 a.m. in huaihua city, said an official from the hunan provincial health bureau.

mother of sick child may have died from bird flu

http://www.recombinomics.com/news/01200901/h5n1_shanxi_h2h2h.html

i wondered why they would take this sick toddler from hunan province all the way to shanxi province. when her mother died of pneumonia, possibly caused by bird flu, her maternal grandparents came and got her. hospitalized in critical condition, her name is peng.

[color="her mother last december 21 ~ 26 have a history of exposure to live birds, december 28, 29 there was a slight fever, due to severe pneumonia in january 2009 death of 6 ~ 7.

the above translation includes the disease onset date for the index case in the hunan / shanxi cluster. the 2 year old daughter developed symptoms on january 7, when her mother died, signaling transmission of h5n1 from mother to daughter. the daughter was then taken to shanxi, where she was hospitalized.

All Eyes on China as Bird Flu Continues Its Comeback

http://www.scottmcpherson.net/journal/2009/1/20/all-eyes-on-china-as-bird-flu-continues-its-comeback.html

Scott McPherson is the CIO (Chief Information Officer of the Florida House of Representatives). He also blogs on bird flu when he has something to say on the topic. He's been busy typing away for the last two days on the situation in China and Indonesia.

You have four infections -- and three deaths -- occurring all over the Chinese mainland. Not confined to one singular province, and not necesarily accompanied by any known die-off of poultry. And to top it all off, the mother of the 2-year-old just died of "pneumonia." Sounds like the authorities need to go back and test for H5N1 on the dead mother, if they can.

And not to say "I told you so," but even York Chow, Hong Kong's Secretary for Food and Health, is saying he is deeply concerned about a possible change in the virus that is making detection in poultry extremely difficult. As you know, I speculated in such a change in my recent blog In Like a Lion. York's call for investigation into possible viral mutation is echoed by Chinese viral researcher and hero Guan Yi and by the Jiangsu Department of Agriculture and Forestry. So you have two Chinese provinces officially declaring there may be something to this viral mutation stuff.

Context is important here. Note that the Chinese New Year officially begins January 26th. This event causes travel for hundreds of millions of Chinese, as they migrate back home or to relatives. The highlight is the Reunion Dinner, held on New Year's Eve. From Wikipedia:

A reunion dinner is held on New Year's Eve where members of the family, near and far away, get together for the celebration. The venue will usually be in or near the home of the most senior member of the family. The New Year's Eve dinner is very sumptuous and traditionally includes chicken and fish.

OK, let's put it all together. We have at least four H5N1 human cases across China, all orccurring within the past month. Three of the cases have been fatal, meaning this strain of H5N1 packs the same degree of lethality as before. These cases are scattered all over mainland China, especially in the central and north/northeast regions. People are going home, usually to the home of the most senior person, and my guess is that most senior person is in rural China. And they eat chicken, of course, meaning rural chicken, recently slaughtered in a backyard or a wet market.

Could Asymptomatic Chickens Force Phase 4?

http://www.who.int/csr/disease/avian_influenza/phase/en/index.html

The WHO currently has us at a pandemic threat level of phase 3.

Experts at WHO and elsewhere believe that the world is now closer to another influenza pandemic than at any time since 1968, when the last of the previous century's three pandemics occurred. WHO uses a series of six phases of pandemic alert as a system for informing the world of the seriousness of the threat and of the need to launch progressively more intense preparedness activities.

The designation of phases, including decisions on when to move from one phase to another, is made by the Director-General of WHO.

http://www.scottmcpherson.net/journal/2009/1/20/could-asymptomatic-chickens-force-phase-4.html

...what if, suddenly, we have lost our most important sentinels in the fight against pandemic H5N1? What if the virus has not changed, but the conditions for infection have? I am saying that if it is true that we have asymptomatic fowl in China and in other parts of Asia, and possibly Egypt, and as a result it is becoming easier for humans to get infected simply because fowl are not doing their duty and dying to warn us, then perhaps it is time to reassess that threat level once again.

When you lose a major source of intelligence when fighting a deadly foe, what do you do? When intelligence experts lose their eyes and ears, they ratchet up the threat level to compensate while they regroup and re-establish their eyes and ears.

Perhaps it is time for the WHO to do the same. If theories hold true, and there is H5N1 present in China and elsewhere that produces asymptomatic, virus-shedding H5N1 avian flu in birds, then we have indeed lost our eyes and ears within the most populous nation on the Earth, the font of all known infectious respiratory diseases. Any prudent homeland security expert would exercise great caution and would raise the threat level.

Another Area of India Infected - Sikkim

http://afludiary.blogspot.com/2009/01/india-sikkim-reportedly-positive-for.html

Bordered by Nepal to its west, Bhutan to the East, West Bengal on the south, and with China on its northern border, the tiny Indian State of Sikkim is pretty much dead center in a bird flu hot-spot.

West Bengal, Assam, and most recently Nepal have all reported bird flu outbreaks over the past 30 days.

Therefore it is not terribly surprising that they have now detected the H5N1 virus among poultry in that state, and a call has gone out to begin culling.

Indonesia

http://www.google.com/hostednews/ap/article/ALeqM5gApQbyawgKLjltct03EvadCi-cCwD95RFGB80

Better late than never, the Indonesians are releasing information on two recent deaths from bird flu that occurred there.

Two Indonesians have died of bird flu, apparently after contact with sick chickens, raising the country's death toll to 115, the Health Ministry said Wednesday.

A ministry statement said a 6-year-old girl in Bekasi, West Java, died on Jan. 2. She got sick after buying a chicken with her parents at a market and was hospitalized for a week.

A 29-year-old woman died on Dec. 16 in Tangerang just outside the capital, Jakarta. She developed flu-like symptoms after visiting a market and died in a hospital five days later.

Bird flu remains hard for people to catch, but health experts worry it could mutate into a form that passes easily between humans, possibly triggering a pandemic that could kill millions worldwide.

Indonesia is considered a potential hotspot for such a mutation, but the country's health minister has refused to share virus samples with the WHO for more than two years.

H1N1 Tamiflu Resistance In China Raises Concerns

http://www.recombinomics.com/News/01210901/H274Y_China.html

This link will be difficult to decipher if you are unfamiliar with the terminology so here is the brief version. H1N1 is one of our regularly recurring seasonal influenzas, the kind that you can get vaccinated for every year. Oseltamivir (Tamiflu) is the antiviral used to treat patients who either have the flu or have been exposed to it. The H1N1 virus has now become resistant to Tamiflu unfortunately, in almost all of its strains by acquiring a piece of genetic material called a SNP, single nucleotide polymorphism (pronounced "snip"). This SNP is H274Y.

A human can be infected with more than one type of influenza. Here is the issue that Dr. Niman is pointing out in this link. As a virologist with an interest in influenza, he reads viral sequences apparently all day. He is seeing flu isolates from China of H1N1, the seasonal flu, and it is showing this resistant trait. Coupled with these new recent cases of bird flu, H5N1 now occurring in China, and asymptomatic birds that are positive for the bird flu, there is the possibility that co-infections of both viruses will take place allowing bird flu to recombine with the seasonal flu, and become resistant to Tamiflu. Tamiflu is just about the only drug we have to treat bird flu. It is being stockpiled by governments across the globe as pandemic preparations continue. We simply can not afford to lose this drug. I hope that this explanation helps because this is a very serious concern.

...an isolate from China, A/Jilin-Chaoyang/1191/08, maps with the US isolates, suggesting this same sub-clade has spread to China. Another isolate from China, A/Beijing-Huairou/15/08, is closely related, raising concerns that H274Y levels in H1N1 in China are also near 100%.

The spread of resistant H1N1 to China raises concerns with regard to co-circulating H5N1. China has just reported four confirmed cases of H5N1 and four additional contacts are suspect cases. These patients, as well as contacts, are treated with oseltamivir, raising concerns that patients or contacts infected with H5N1 could also be infected with H1N1 with H274Y, which could lead to the emergence of H5N1 with H274Y.

Japanese Govt plans survey on Tamiflu-resistant flu

http://www.yomiuri.co.jp/dy/national/20090114TDY02309.htm

It would appear that the Japanese are worried about the new resistant strains of Tamiflu resistant seasonal flu. They use a lot of Tamiflu in Japan to treat seasonal influenza, much more so than does any other country. H1N1 is the seasonal flu that has developed resistance.

Japan has reason to be concerned. They know that some of their wild birds, mostly swans, carry bird flu, H5N1, and they have fought the virus in some not so recent outbreaks in poultry.

They clearly "get" that this could be a hugh problem. Tamiflu is the barrier that has kept bird flu at bay. If bird flu also develops Tamiflu resistance, there will only be the mitigation strategies such as isolation, hand washing, masks, and social distancing to protect humans from the disease. For treatment once infected, there will be only supportive care for most cases.

Tamiflu resistance in H1N1 seasonal flu has appeared just about everywhere across the globe.

The Health, Labor and Welfare Ministry plans to conduct a nationwide survey of patients infected with a strain of influenza virus resistant to the major oral drug Tamiflu this winter, it was learned Tuesday.

While an increasing number of cases of the drug-resistant virus have been reported in the United States and Europe, the spread of such a virus in the country likely will disrupt medical institutions because Japan is one of the world's largest users of the drug.

... among foreign patients, including those from Southeast Asia, infected with H5N1 bird flu virus, which some experts fear could mutate into new strains of influenza that can be passed on to humans, those who did not take Tamiflu at an early stage all died. Considering the situation, the government and other organizations have stockpiled Tamiflu for 28 million people, including a supply being distributed as part of efforts to head off an outbreak of new strains of influenza.

However, if the Tamiflu-resistant virus spreads across the country while a new strain of influenza against which human beings have no immunity occurs at the same time, people likely will be infected with both viruses, leading the new strain of influenza to become resistant to Tamiflu. And it will result in an expansion of infection with the new strain as the stockpiled Tamiflu will not work on the patients.

Antiviral Drug Use and Employer Stockpiling Webcast

http://pandemicflu.gov/news/panflu_webinar8.html

This webcast took place in December therefore the information is fairly up to date. Benjamin Schwartz, HHS and Lisa M. Koonin, CDC were interviewed regarding the new federal guidelines for antiviral stockpiling of antivirals by employers for a pandemic.

These are the recommendations for obtaining antivirals:

Anyone who is sick will be given Tamiflu.

The critical employees such as HCW, police, firefighters, EMTs, power plant workers etc. need to be protected with prophylactic antivirals provided by their employers. That means if you are working for a hospital, you are a critical employee if the hospital needs you to be there for patient care or for the functioning of the hospital, for example. Your employer can not expect you to work without providing this protection.

In facilities such as prisons or nursing homes or college dorms where a group has been exposed to an infected person, they will be given antivirals.

They are not going to give meds to the families of any workers.

As an aside, Dr. Benjamin Schwartz from HHS also talked about the recent discovery of Tamiflu resistance in the seasonal flu, H1N1. Initially he starts out dismissing any concerns that the bird flu virus H5N1 might also develop drug resistance but, later in the webcast says it would be "prudent" to use more than one antiviral suggesting that Relenza, the inhalant drug also be stockpiled.

He sounded very reassuring when he said that these drugs would be available. I wondered if he was aware that some states opted out of the federal program that would have helped pay for these antivirals, but maybe he just forgot to mention that when he said that hospitals might be able to acquire antivirals from their states. Or maybe I just misunderstood what he was saying...

China Reports 4th Human H5N1 Fatality This Month

http://afludiary.blogspot.com/2009/01/china-reports-4th-bird-fatality-this.html

A 31-year-old Chinese woman has died of bird flu, becoming the country's fourth victim of the disease this year, the state Xinhua news agency said on Saturday.

The woman fell ill on January 10 after visiting a poultry market and died early on Friday in northwest China's Xinjiang region, Xinhua said, citing local health authorities.

The woman was China's third avian flu victim in seven days...

Up until this month, China had only reported 30 human infections. That out of a population of 1.3 billion people. Or roughly 1 for every 43 million people.

Vietnam, with a population of 88 million, has reported 106 infections over roughly the same time period, or 1 in every 800,000 persons.

Why is there a 50 fold difference in reported attack rate between China and Vietnam?

Good question, but nobody really believes that there have not been more cases of bird flu than what the Chinese are admitting to, do they? This is the country that officially denied having any SARS cases until they couldn't hide them anymore...
