I'm a school nurse (new role for me) at an American International School in Dhaka, Bangladesh. We have a gardener with Hep B and many of his fellow workers are concerned, as well as the school superintendent. He has his own eating utensils but it just came to my attention that he drinks from the water points around school. How concerned should the school be? All the overseas hired teachers have Hep B vaccinations but not all the locally hired teachers. It is also recommended that the students have Hep B immunizations but not required. This is a country where probably over 10% of the population has Hep B. What do you recommend? We also have a bus monitor and receptionist (dual job) person with Hep B.
