Swine flu virus has not mutated: WHO chief
HONG KONG (AFP) - – The head of the World Health Organization
said Monday that the swine flu virus had apparently not yet mutated
into a more serious disease and that the development of vaccines
was proceeding on track.
The vaccines for (A)H1N1 influenza produced so far have been
very effective, WHO Director-General Margaret Chan said at the
opening ceremony for the organisation's annual Western Pacific
meeting in Hong Kong.
"The virus can mutate any time. But from April to now, we can
see from the data given to us by laboratories worldwide that the
virus is still very similar (to the previous state)," Chan told
reporters.
Ideally, three billion doses of vaccines could be produced
worldwide annually, she added, noting that China had already begun
to vaccinate people.
She also said the Hong Kong government could relax its measures
against a swine flu outbreak "step-by-step", advising them in the
long-run to focus resources on saving patients and reducing the
number of serious cases.
Chan said that only high-risk patients such as the elderly, the
obese and those with underlying illnesses would be severely
affected by the disease.
Swine flu in Hong Kong has raised fears of a repeat of the 2003
Severe Acute Respiratory Syndrome (SARS) outbreak, when almost 300
people died and concern about the mysterious disease turned the
metropolis into a virtual ghost town.
Chan managed Hong Kong's response to avian influenza and SARS
during her nine-year stint as Hong Kong's director of health.
Top of the agenda for the WHO's meeting this week will be how to
combat the swine flu pandemic in developing nations.
While the Americas still has the highest death toll from the
virus, cases are expected to increase in the region as the northern
hemisphere enters winter.
There are fears that poorer countries will not get enough
vaccines, despite a pledge last week by the United States and eight
other nations to make 10 percent of their swine flu vaccine supply
available to others in need.
Developing countries are not only unable to produce the vaccine
for the A(H1N1) flu virus but their people are more vulnerable to
infection because of poverty, crowded living conditions and lack of
healthcare, according to the WHO.
In the Western Pacific there are about a million people living
in poor conditions without access to healthcare, WHO regional
director Shin Young-soo told reporters Sunday.
