Professor warns of virus taking hold in autumn
THE DAILY TELEGRAPH
LONDON — An Influenza A (H1N1) pandemic is likely to strike the United Kingdom in September or October, gathering strength as it spreads, a leading expert said yesterday.
Professor John Oxford, an expert in virology at the University of London's Queen Mary School of Medicine, said that even though only 229 cases of H1N1 flu have been confirmed in the UK so far, he was certain a flu pandemic would take hold as autumn begins.
Students going back to school and people returning to work after the summer break would give the flu the "opportunity" it needs, he said.
He warned that a pandemic is likely to affect the UK before a vaccine becomes available, adding that the vaccine — which is expected to be ready in October or November — would only cover about15 per cent of the population.
Prof Oxford praised campaigns urging people to observe good hygiene — such as using tissues and not coming into contact with infected people — but said that would not halt the virus altogether.
"Problems at the moment are fairly low, with schoolchildren and the odd sporadic case in the community. But when children go back to school in September, the virus has an opportunity and normally it takes it. That's the scenario we should prepare for."
He said children were usually involved in an outbreak because they like to be in close contact. "Children are very social, they play together and put their arms around each other, they kiss each other. Also, their hygiene levels are not very high."
He added: "I view tackling flu like a medieval castle, with several layers of defence: You've got the outer layer which is hygiene and social distancing, then the virus breaks through that and then we have antivirals like Tamiflu and then the final layer is the vaccine. You chuck all of this at the virus. You can't stop it, but you can slow it down."
Prof Oxford said there has already been sporadic cases which were not linked with anyone coming into the UK from the United States or Mexico.
"That does suggest that the virus is silently spreading around," he said.
He said the current estimate that 50 per cent of the population may get infected was on the "low side".
He added: "The virus will be like a bushfire."
In order to avoid the flu, people should keep their distance from others, wash their hands regularly and cough into the crook of your arm.
The World Health Organisation's current threat level of a flu pandemic is at level five. Declaration of a pandemic would move it to level six.
A spokesman for the Department of Health said: "Our strategy to slow the spread of the disease appears to have been effective, and the UK's arrangements continue to ensure that we are well-placed to deal with this new infection. But we must not be complacent — it is right to prepare for the possibility of a global pandemic."
