Bird Flu Flies From Human to Human

Another case of the H5N1 Bird Flu being spread from human-to-human.

The case is currently isolated, however it confirms the potential for it to become an epidemic for humans as it has already happened in Indonesia and Thailand.

WHO confirms human-to-human bird flu case

Virus passed among Pakistani family, but no apparent risk of wider spread

GENEVA – The World Health Organization (WHO) confirmed on Thursday a single case of human-to-human transmission of the H5N1 bird flu virus in a family in Pakistan but said there was no apparent risk of it spreading wider.
A statement from the U.N. agency said tests in its special laboratories in Cairo and London had established the “human infection” through presence of the virus “collected from one case in an affected family.”
But it said a WHO team invited to Pakistan to look into an outbreak involving up to nine people, from late October to December 6 had found no evidence of sustained or community human-to-human transmission.
No identified close contacts of the people infected, including health workers and other members of the affected family, had shown any symptoms and they had all been removed from medical observation, the WHO added.

The outbreak followed a culling of infected chickens in the Peshawar region, in which a veterinary doctor was involved. Subsequently he and three of his brothers developed proven or suspected pneumonia.

The brothers cared for one another and had close personal contact both at home and in the hospital, a WHO spokesman in Geneva said. One of them, who was not involved in the culling, died on November 23.

His was the human-to-human transmission case confirmed by the WHO. The others all recovered.

“All the evidence suggests that the outbreak within this family does not pose a broader risk,” the WHO spokesman told Reuters. “But there is already heightened surveillance and there is a need for ongoing vigilance.”

It was the first human-to-human case of H5N1 transmission in Pakistan, while others have been confirmed in Indonesia and Thailand in similar circumstances of what the WHO calls close contacts in a very circumscribed area.

Global health experts fear the virus — which has killed 211 people out of 343 infections reported since 2003 — could mutate into a form that spreads easily from one person to another, possibly triggering a pandemic that could kill millions.

  2. H5N1 avian flu: Spread by drinking water into small cluster

    Human to human and contact transmission of influenza occur – but are overvalued immense. In the course of Influenza epidemics in Germany recognized cluster are rarely (9% of the cases in the season 2005).
    In temperate climates the lethal H5N1 avian flu virus will be transferred to humans strong seasonal in the cold via cold drinking water, as with the birds feb/mar 2006.
    Recent research must worry: So far the virus had to reach the bronchi and the lungs in order to infect humans. Now it infects the upper respiratory system (mucous membranes of the throat e.g. when drinking and mucous membranes of the nose and probably also the conjunctiva of the eyes as well as the eardrum e.g. at showering). In a few cases (Viet Nam, Thailand) stomach and intestine by the H5N1 virus were stricken but not the bronchi and the lungs. The virus might been orally taken up, e.g. when drinking contaminated water.
    The performance to eliminate viruses of the drinking water processing plants in Germany 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 the strong seasonal waterborne infections like norovirus, rotavirus, salmonellae, campylobacter and – differing from the usual dogma – influenza are mainly triggered by drinking water dependent on the drinking water temperature (in Germany minimum feb/mar – maximum august). There is no evidence that influenza primary is transmitted by saliva droplets. In temperate climates the strong interdependence between influenza infections and environmental temperatures can’t be explained with the primary biotic transmission by saliva droplets from human to human with 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% of inhabitants have a central public water supply with older and better protected water. Therefore in Germany cold water is decisive to virulence of viruses.
    In hot climates/tropics the flood-related influenza is typical after extreme weather and natural after floods. Virulence of 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 water temperature for infection may be higher as in temperate climates.

    Epidemiological Analysis:

  3. Very interesting information. I am a bit sceptical in terms of transmission of H5N1 as it’s origins are still unknown. There is theory that this was created by humans in a lab in China, if that is the case, there is a lot of potential for divation from standard strains of influenza.
    Do you have links to the information you posted in English, I hate running stuff like that through translation programs as they tend to be inaccurate as they are literal translations…
