A new strain of H1N1 emerging?

The H1N1 swine flu virus might be mutating. A new form of the virus has started to predominate in Australia, New Zealand and Singapore according to a new report in Eurosurveillance.

The World Health Organization (WHO) says more study will tell whether the new strain is deadly and whether the current vaccine will protect against it.

A vaccine update may be required sooner than might have been expected. It is possible it is both more deadly and also able to infect people who have been vaccinated, the WHO says.

Flu viruses are always mutating. The H1N1 swine flu virus has been consistent with almost no mutation.

The report states, "The virus has changed little since it emerged in 2009, however, in this report we describe several genetically distinct changes in the pandemic H1N1 influenza virus."

Researchers say the changes are not significant now. But there are some cases of vaccinated people who got sick and some deaths. However, there’s not enough data to determine if there were other things making the patients more susceptible.
