- The latest outbreak of sever acute respiratory syndrome
(SARS) in China, with eight confirmed or suspected cases so far and hundreds
quarantined, involves two researchers who were working with the virus in
a Beijing research lab, the World Health Organization (WHO) said on Monday
(April 26).
-
- "We suspect two people, a 26-year-old female postgraduate
student and a 31-year-old male postdoc, were both infected, apparently
in two separate incidents," said Bob Dietz, WHO spokesman in Beijing,
told The Scientist.
-
- The woman was admitted to hospital on April 4, but the
man apparently became infected independently 2 weeks later, being hospitalized
on April 17. Both worked at the Chinese Institute of Virology in Beijing,
part of China's Center for Disease Control.
-
- At a news conference in Manila this morning, Associated
Press reported, WHO Western Pacific Regional Director Shigeru Omi criticized
the laboratory's safeguards and said the authorities did not know yet whether
any foreigners had been carrying out medical research in the facility and
had since left the country. Laboratory safety "is a serious issue
that has to be addressed," he said. "We have to remain very vigilant."
-
- China has level three research guidelines and rules in
place for handling the SARS virus, which are "of acceptable quality"
to WHO, Dietz told The Scientist. But "it's a question of procedures
and equipment. Frankly we are going to go in now a take a very close look,"
he said.
-
- "We have a team of two or three international experts
that's arriving in a day or two. They are going to go into the labs with
Ministry of Health people and find out what happened here," Dietz
said.
-
- "We've been told we'll have full access, be able
to test all the surfaces, interview people who worked there, and look at
documentation to find out what was being done," Dietz said. "We're
not releasing the names of the experts yet, but once you see the names
you'll recognize them. They will be international experts from the relevant
disciplines."
-
- In the meantime, the lab has been closed, and the 200
staff have been put in isolation in a hotel near another lab in Cham Ping,
about 20 kilometers North of Beijing. China is rushing its own investigative
teams to check lab security, according to state media.
-
- Antoine Danchin, an epidemiologist with the Hong Kong
University-Pasteur Research Center, who studied the SARS epidemic in Hong
Kong, told The Scientist the latest incidents were probably the result
of lab accidents.
-
- "Normally, it's not possible to contaminate people
even under level two confinement, if the security rules are obeyed, with
the appropriate hoods, and so on," Danchin said. SARS work requires
level three. "So it suggests there has been some mishandling of something."
-
- "The lab might have all the right rules, but the
people may not comply! For example, notebooks are not supposed to be taken
out, a lot of things like that. A virus doesn't jump on people!" Danchin
said. However WHO Beijing is relatively sanguine about the current threat,
despite the fact that the 26-year-old infected had taken a long journey
on the country's rail network. The index cases are known, and contacts
had been traced, Dietz said. "We see no significant public health
threat at this point."
