Bird Flu strain. . . World Organisation for Animal Health advises Zim on Avian Flu

June 12, 2017 Business
...
Said the organisation?s head of the communication unit Dr Catherine Bertrand-Ferrandis:

?Since HPAI H5N8 subtypes of the virus cause high mortality in domestic poultry, the organisation recommend that Veterinary Services in risk countries such as Zimbabwe and neighbouring countries increase prevention efforts through bio-security to minimise contact between wild birds and poultry and enhance surveillance and preparedness.
...
?Because of the stability of the virus in the environment and highly contagious nature, strict biosecurity measures and good hygiene are essential in protecting against disease outbreaks,? she said.
...
?To date no human influenza cases have been reported to be linked with the H5N8 strain. As a precaution, people working with, or in contact with, poultry that are infected with (or suspected of being infected with) AI viruses are recommended to wear protective clothing, including face masks, goggles, gloves and boots.
