Schools Close as Spike in Swine Flu Cases Hits Japan


Schools Close as Spike in Swine Flu Cases Hits Japan

In a sudden surge that took Asian health officials by surprise, the Japanese health ministry confirmed on Monday at least 125 new cases of the A virus — or swine flu — in the country’s western prefectures of Osaka and Hyogo. Officials have shut down around 1,000 schools since many of the
infected were high-school students. Japan, along with the United Kingdom and Spain, is now one of the few countries outside of North America where the World Health Organization fears sustained human-to-human transmission of the virus could lead to the onset of a full-blown pandemic. “We must respond calmly and appropriately,” warned Japanese Prime Minister Taro Aso at a press conference Monday morning.

Panic over the threat of a global pandemic has subsided since early May, as governments across the world stepped up preventive measures that seem to be keeping the virus under control. But Japan’s weekend cases are not alone: By Sunday, the UK confirmed 14 more cases, while Turkey and India both announced their first, bringing the number of countries affected to 39. In Hong Kong, a 23-year-old student returning from North America became the territory’s third swine flu case, and the 63 passengers who sat closest to him on his flight are being tracked by government officials to be quarantined for a week in a remote holiday camp in the region. In Beijing, another student recently returned from the U.S. video-chatted with Chinese Premier Wen Jiabao from her hospital bed after being confirmed as the mainland’s third swine flu patient.

Authorities in East Asia — which has suffered heavily in recent years from outbreaks of various infectious diseases — have clamped down early and quickly on suspected cases of swine flu. Just over a week ago, Hong Kong released some 300 people stuck at a business hotel after cooping them up in a week-long quarantine when one guest was found to be carrying the virus. The city, one of Asia’s busiest business and travel hubs, was ravaged by the 2003 SARS epidemic, as well as subsequent scares over avian flu. As a consequence, its counter-pandemic procedures are among the most draconian in the world, while its epidemiology laboratories are among the most advanced.

But the spike in Japan’s cases shows that swine flu can infiltrate safety nets there and elsewhere, lingering beneath the radar of health monitors. Government officials are still unsure of how the virus reached Osaka and Hyogo, or how long it has been circulating in the region’s highly populated urban centers of Osaka and Kobe. In addition to schools, movie theaters in the outbreak-hit prefectures were also advised to close today and Tokyo has now blocked its own educational institutions from visiting the area on field trips. “We must be prepared for a further expansion [of the virus],” says Toru Hashimoto, Osaka’s governor.

Japan’s four earlier suspected swine flu cases came from travelers
inbound from North America, but this new bout appears to be wholly domestic.
Most of the cases involve teenagers — the first confirmed infected on
Saturday were high-school students on a volleyball team — but those sick
with the new strain of flu now range from as young as 5 years old to 60. “It
circulated silently without anybody thinking of it,” says Peter Cordingley,
spokesman for the WHO in Manila. “The virus is highly transmittable and signs of it
breaking out of a contained area into the greater community must be watched
and taken very seriously.”

Swine flu’s known symptoms vary little from winter flu, which is one of the
main reasons why it is difficult to track. Those with underlying health
problems, such as diabetes or heart disease, seem especially vulnerable —a particular concern for a nation like Japan with a high elderly population. None of the infected are in critical condition, but, as
deadly influenza pandemics have proved IN the past, the current strain of
A may mutate and become far more virulent — and lethal — by the next flu
season.

Seto Wing-hong, a leading microbiologist and a member of the Hong Kong
government’s Influenza Research and Response Group, is cautiously optimistic
about the world’s ability to reckon with this new disease. “There is every chance
that it will spread,” he says. “But these things have long incubation
periods and we, like never before, have the luxury of time and high-speed
technology to track strains of viruses again and again, and to fine tune our
actions in response.” Seto believes a useable vaccine can be made and
distributed by September or October.

Still, with the world economy so tightly integrated and millions on the move
every day, the threat of an epidemic haunts the health officialdom of all
governments. Kiyoshi Kurokawa, a public health policy expert and adviser to
the Japanese prime minister, urges continuous communication between
governments, hospitals dealing with outbreaks and international agencies.
“Keeping the process transparent is key,” he says. As Japan comes to grips
with the virus in its midst, the enemy it — and the world — knows is
far better than the one it does not.
