Spread of Bird Flu in to Bihar could be really bad news.

The State Government of Bihar today ordered culling of chickens in six panchayat areas in Katihar district, adjacent to affected Malda district of West Bengal, “as a preventive measure”, a day after imposing a blanket ban on entry of poultry from the neighbouring state.
Earlier, contrary to the claims of the West Bengal govt that bird flu has been contained, the deadly virus on Wednesday was detected in samples of dead chicken in Cooch Behar district.
The state of Bihar is under-developed even when compared to most of the other regions of India.
The poverty and lack of education, specially within the large Muslim population in Bihar makes it an ideal target for the killer virus.
Basic Hygiene and common sense give way to tradition and religious practices in this part of India
I have always believed that the number of the human victims of the bird flu are directly related to the custom of Halal, where the poultry is killed by making a cut in the throat of the bird and letting the blood flow out while the bird is held up side down by its feet.
Bihar like the State of West Bengal, is host to millions of refugees from the neighbouring country of Bangladesh, where H5N1 is thought to be endemic now.
So if bird flu in Bengal is bad, it could be a lot worse in Bihar.

  1. Spread of avian flu by drinking water

    There is a widespread link between avian flu and water, e.g. in Egypt to the Nile delta or Indonesia to residential districts of less prosperous humans with backyard flocks and without central water supply as in Vietnam: http://www.cdc.gov/ncidod/EID/vol12no12/06-0829.htm. See also the WHO webside: http://www.who.int/water_sanitation_health/emerging/h5n1background.pdf and http://www.umwelt-medizin-gesellschaft.de/ abstract in English “Influenza: Initial introduction of influenza viruses to the population via abiotic water supply versus biotic human viral respirated droplet shedding” and http://www.thelancet.com/journals/laninf/article/PIIS1473309907700294/abstract?iseop=true “Transmission of influenza A in human beings”.
    Avian flu infections may increase in consequence to increase of virus circulation. Transmission of avian flu by direct contact to infected poultry is an unproved assumption from the WHO. Infected poultry can everywhere contaminate the drinking water. All humans have contact to drinking water. Special in cases of small water supplies this pathway can explain small clusters in households. In hot climates and the tropics flood-related influenza is typical after extreme weather and natural after floods. The virulence of the influenza virus depends on temperature and time. If young and fresh H5N1 contaminated water from low local wells, cisterns, tanks, rain barrels or rice fields is used for water supply the water temperature for infection may be higher (at 24°C the virulence of influenza viruses amount to 2 days) as in temperate climates (for “older” water from central water supplies cold water is decisive to virulence of viruses: at 7°C the virulence of influenza viruses amount to 14 days).
    Human to human and contact transmission of influenza occur – but are overvalued immense. In the course of influenza epidemics in Germany, recognized clusters are rare, accounting for just 9 percent of cases e.g. in the 2005 season. In temperate climates the lethal H5N1 virus will be transferred to humans via cold drinking water, as with the birds in February and March 2006, strong seasonal at the time when drinking water has its temperature minimum.
    The performance to eliminate viruses from the drinking water processing plants regularly does not meet the requirements of the WHO and the USA/USEPA. Conventional disinfection procedures are poor, because microorganisms in the water are not in suspension, but embedded in particles. Even ground water used for drinking water is not free from viruses.
    In temperate climates strong seasonal waterborne infections like the norovirus, rotavirus, salmonella, campylobacter and – differing from the usual dogma – influenza are mainly triggered by drinking water, dependent on the water’s temperature (in Germany it is at a minimum in February and March and at a maximum in August). There is no evidence that influenza primarily is transmitted by saliva droplets. In temperate climates the strong interdependence between influenza infections and environmental temperatures can’t be explained by the primary biotic transmission by saliva droplets from human to human at temperatures of 37.5°C. There must be an abiotic vehicle like cold drinking water. There is no other appropriate abiotic vehicle. In Germany about 98 percent of inhabitants have a central public water supply with older and better protected water. Therefore, in Germany cold water is decisive to the virulence of viruses.
