THE H1N1 flu pandemic remains moderate and its effects are probably closer to those of 1957 and 1968 than the far more deadly 1918 version, the World Health Organization said yesterday.
Margaret Chan, WHO director-general, said the H1N1 pandemic appeared to be easing in the northern hemisphere but could still cause infections until winter ends in April. It was too soon to say what would happen once the southern hemisphere enters winter and the virus becomes more infectious.
"An event similar to the 1918 pandemic was feared, when what happened was probably closer to the 1957 or 1968 pandemics," Chan said in a speech opening a week-long meeting of the WHO's executive board.
The 1918 pandemic, known as the Spanish flu, swept around the world at the end of World War I, killing some 40 million to 50 million people.
Governments have taken appropriate steps this time to protect their populations and will ultimately earn "the highest marks," said Chan, a former health director of Hong Kong. "Though the burden on emergency rooms and intensive care units has been heavy, nearly all health systems have coped well."
Populations should continue to be vaccinated, she added, reiterating that the vaccine was safe and effective.
In public health crises, it was better to "err on the side of caution," Chan said. "I believe we would all rather see a moderate pandemic with ample supplies of vaccine than a severe pandemic with inadequate vaccine."
Nearly 14,000 official deaths have been reported by more than 200 countries since the virus emerged in North America last April, but it will take at least one to two years after the pandemic ends to establish the true toll, she said.
WHO experts say the actual death rate could be much higher than the number of laboratory-confirmed cases so far.
Data on Africa was scarce, she warned.
"We are concerned that some countries in the western part of the continent remain susceptible to intense waves of transmission," Chan said.
