The UK Health Security Agency (UKHSA) has reported the detection of bird flu in two poultry workers in England.
However, there have been no signs of human-to-human transmission, according to the UKHSA.
Both cases showed no symptoms of avian influenza and have tested negative for the virus.
Low Risk to Human Health
Health officials have stated that the detections do not change the level of risk to human health, which remains very low for the general population.
They reassured the public that the likelihood of contracting avian flu is minimal.
Challenges in Detecting Infection
Avian flu infection can occur through the contamination of the nose and throat from inhaling material present on affected farms.
However, distinguishing true infection from contamination in individuals without symptoms can be challenging.
Background on Bird Flu and Surveillance Program
Bird flu, also known as H5N1, has been circulating among poultry and wild birds for 25 years, according to the World Health Organization (WHO).
Although rare cases of transmission to humans have occurred, sustained human-to-human transmission has been uncommon.
The UKHSA’s asymptomatic surveillance program detected the cases in poultry workers by testing their nasal and throat swabs for the presence of the influenza virus.
Monitoring and Precautions
The UKHSA emphasizes the need to monitor individuals who have been in contact with confirmed cases of avian influenza.
Professor Susan Hopkins, Chief Medical Advisor at UKHSA, stresses that the current evidence suggests that avian influenza viruses do not easily spread to humans.
However, close contact with infected birds can lead to transmission. It is crucial to avoid touching sick or dead birds and follow the appropriate reporting protocols.
Testing and Antiviral Measures
Individuals with the highest risk of exposure to avian flu may be offered testing and antiviral medication to protect against infection and reduce the risk of spreading the virus, as stated by the UKHSA.
Modeling and Policies for Bird Flu Pandemic
The UKHSA has formed a group of experts, including Professor Neil Ferguson from Imperial College, to develop modeling for a potential bird flu pandemic.
The group is examining policies such as the introduction of lateral flow tests for the disease.
