Governments around the globe have moved swiftly and aggressively against the fast-spreading A/H1N1 flu virus. But should it evolve into an especially deadly strain, the consequences will likely overwhelm even the most advanced health systems in the U.S. and other Western countries.

By one important measure -- stockpiles of antiviral drugs such as Tamiflu -- the U.K. is among the countries best prepared to cope with the emerging pandemic. It has enough of the medicine on hand to treat 33 million people, or 54% of its population. France is also a leader, with drugs also to treat 54% of its people, as well as one billion surgical masks in its stockpile. Austria, with antivirals for 40%, and Japan, at 28%, are close behind.

India, which announced plans Thursday to purchase enough Tamiflu to treat nine million people, adding to its current stock of doses to treat one million, lags behind other nations. In Africa, which hasn't reported any confirmed cases of the new virus, the World Health Organization's regional office has about one million doses available to countries in need, according to Phillip Muthoka, who works in Kenya's health ministry. He has just 400 doses of Tamiflu now.

With scarce resources, a poorly organized health system, and a population battling other diseases, African nations would be especially vulnerable should a deadly strain of the virus take hold on that continent, officials say. 'We are very concerned,' Dr. Muthoka said. 'Our people are traveling all over.'

For its part, the U.S. has enough antiviral medication in reserve to treat 50 million people, or about 16% of the population. It has also poured some $7 billion into strengthening its public-health infrastructure since the Sept. 11, 2001, attacks and the SARS and avian flu epidemics prompted concern about the ability of communities to respond to such events. Improved surveillance and detection efforts and better-trained local public-health agencies are among the payoffs.

Another critical weapon, flu-vaccine development, remains hampered by 1950s production technology. It can take several months to develop a vaccine for a new virus, and much longer to produce and deliver it to enough people to have an impact.

Meanwhile, governments and public-health officials on high alert around the world are using lessons learned from past outbreaks to mitigate the impact of the new virus. Singapore, in one of the stricter moves by a government to stop potential infection from travelers abroad, announced Thursday that people who have recently traveled to Mexico will be quarantined for seven days when they enter Singapore and undergo phone surveillance for symptoms of swine flu.

Japan has posted military doctors and nurses at Narita airport near Tokyo, using thermal-imaging cameras to screen passengers coming in on flights from Mexico, Canada and the U.S. If a case of the flu is reported, the government plans to open several hundred 'fever clinics' across Japan.

To raise awareness of the flu's dangers, the French government has posted billboards in major airports warning passengers traveling to Mexico to avoid large crowds and to wash their hands regularly. The country also urged the European Union to suspend outward flights to Mexico, but the EU ruled out the idea on Thursday.

In Southern Africa, health ministers from countries who belong to the Southern African Development Community, a regional regulatory body that deals with trade, politics and other issues, put their countries' surveillance system on 'high alert' and agreed on a travel advisory against visiting affected countries.

So far, the new flu strain appears mild. Adewale Troutman, director of the Metro Louisville Department of Health and Wellness in Kentucky, says it resembles the pattern of regular flu with 'multiple cases and not that many hospitalizations.'

'The whole public-health system is much better prepared now than it was five to 10 years ago,' said Jeffrey Koplan, director of the Global Health Institute at Emory University in Atlanta, and a former director of the CDC. Still, he said, 'preparedness is a relative thing. Any system has constraints in capacity.'

Eric  - How is swine flu treated?     |Registered |2009-05-04 23:31:12
The new swine flu virus is sensitive to the antiviral drugs Tamiflu and
Relenza. The CDC recommends those drugs to prevent or treat swine flu; the drugs
are most effective when taken within 48 hours of the start of flu symptoms. But
not everyone needs those drugs; many of the first people in the U.S. with
lab-confirmed swine flu recovered without treatment. The Department of Homeland
Security has released 25% of its stockpile of Tamiflu and Relenza to states.
Health officials have asked people not to hoard Tamiflu or Relenza.
Eric  - How does swine flu spread? Is it airborne?     |Registered |2009-05-04 23:32:53
The new swine flu virus apparently spreads just like regular flu. You could
pick up germs directly from an infected person, or by touching an
object they recently touched, and then touching your eyes, mouth, or
nose, delivering their germs for your own infection. That's why you should
make washing your hands a habit, even when you're not ill. Infected
people can start spreading flu germs up to a day before symptoms start, and
for up to seven days after getting sick, according to the CDC.

The
swine flu virus can become airborne if you cough or sneeze without covering
your nose and mouth, sending germs into the air.

The U.S. residents
infected with swine flu virus had no direct contact with pigs. The CDC says
it's likely that the infections represent widely separated cycles of
human-to-human infections.
