Avian flu detected in two individuals taking part in testing programme

UKHSA has detected influenza A (H5) virus in two poultry workers, following the introduction of an asymptomatic testing programme for people who have been in contact with infected birds.

The two people returning positive tests are known to have recently worked on an infected poultry farm in England. Neither has experienced any symptoms of avian influenza and both have since tested negative. Detection of avian influenza in poultry workers can follow contamination of the nose and throat from breathing in material on the affected farm or can be true infection. It can be difficult to distinguish these in people who have no symptoms.

Based on the timing of exposures and test results, one individual is likely to have had contamination of the nose and/or throat from material inhaled on the farm, while for the second individual it is more difficult to determine which is the case. Further investigation is under way but meanwhile precautionary contact tracing has been undertaken for this second individual.

The UK Health Security Agency (UKHSA) has not detected evidence of human-to-human transmission and these detections do not change the level of risk to human health, which remains very low to the general population.

Professor Susan Hopkins, Chief Medical Advisor at UKHSA, said: “Current evidence suggests that the avian influenza viruses we’re seeing circulating in birds around the world do not spread easily to people. However, we know already that the virus can spread to people following close contact with infected birds and this is why, through screening programmes like this one, we are monitoring people who have been exposed to learn more about this risk.

“Globally there is no evidence of spread of this strain from person to person, but we know that viruses evolve all the time and we remain vigilant for any evidence of changing risk to the population.”

UKHSA has contact traced close contacts where needed.
