The World Health Organization confirms the emergence and the rapid spread of AH3N2 flu strain

The new variant, called A/H3N2 K, which was first identified in Australia and New Zealand in August, has now been detected in over 30 countries.

Medical experts recommend flu shots to reduce the symptoms of A/H3N2 K.

“Current epidemiological data do not indicate a major increase in disease severity, although this genetic shift marks a notable evolution in the virus,” said Dr Wenqing Zhang of the Department of Epidemic and Pandemic Threats Management of the World Health Organization. “Any time there is a significant genetic change to influenza strains there is the danger of other mutations,” he says.

He added that label of “super flu” attached to A/H3N2 K by the media is “unfortunate” since it suggests a high level of danger.

The evolution of the influenza viruses makes it imperative to constantly update the vaccine composition. As per the WHO, there are around one billion cases of seasonal influenza annually, including up to five million cases of severe respiratory illness. Up to 650,000 deaths each year are owing to seasonal influenza-related respiratory disease.

Based on current WHO updates, the new virus strain ended up being predominant in the United Kingdom and Japan. It has been reported that nearly 90 per cent of the flu samples in these countries are now A/H3N2 K. A similar trend has also been observed in the United States and Canada.

“Vaccination remains our most effective defense, including against this flu, particularly for high-risk populations and those taking care of them,” Dr Zhang insisted. “At the moment, influenza vaccines to not specifically address the A/H3N2 K variant but they remain very effective in reducing the effects of symptoms.”

Experts say early evidence suggests that current seasonal vaccines continue to offer protection against severe diseases and reduce the risk of hospitalization.

Preventive measures:
Simple preventive measures like regular handwashing, wearing masks in crowded spaces, covering nose and mouth while coughing and sneezing, staying home when unwell and drinking plenty of fluids can help in preventing the spread of the disease.
