First case of swine flu ‘presumed’ in Korea

First case of swine flu ‘presumed’ in Korea

Reported April 29, 2009

Korea may see its first outbreak of swine flu after the new strain claimed more than 100 lives in Mexico and other countries around the globe over the past two weeks, said the country’s health authorities yesterday.

During the day, the Korea Centers for Disease Control and Prevention raised the status of a 51-year-old Korean woman back from a trip to Mexico from “suspected” of infection to “presumed” infected after close examination.

Patients placed under the presumed infection category test positive for type-A influenza, the cause of influenza in pigs, but negative for any of the known human variants of that virus – the H1 and H3 human subtypes.

Patients classified under “suspected infection” refer to a wider range: people showing symptoms of the respiratory disease who have traveled to regions where the outbreak has occurred or have contracted swine flu from infected humans or animals.

Confirmation of an infection can be made after more laboratory tests , so final diagnosis on the Korean woman might take up to two weeks, according to the state-run agency.

 

 

Immediately after identifying a possible infection, the center, which is under the Health Ministry, started investigating anyone who was on the same flight or has shared her living space since she returned.

The center said she went to Morelos, Mexico via Los Angeles on April 17 and returned to Korea on April 26, again via Los Angeles. She made a voluntary report on her symptoms including fever, cough and runny nose after her return. She has been placed in an isolation unit in a hospital and is showing “typical symptoms” of the swine influenza virus, according to Lee Jong-ku, director of the center.

Her travelling companion underwent an immediate medical check after she returned yesterday via Incheon International Airport, according to the disease control center.

Korean health authorities are currently tracking the passengers on the flight from Los Angeles and anyone who went to church with her in Gyeonggi. The 40 people she lives with in an unidentified institution have taken the anti-viral medicine Tamiflu, authorities said.

“We can’t rule out the possibility that more swine flu patients entered Korea from Mexico and the United States,” said Lee. “But please remember that no case of severe acute respiratory syndrome, or SARS, infection was confirmed in 2003 in Korea.”

He said the public has to take extra care with personal hygiene and report to the nearest public health centers should anyone have swine flu symptoms less than seven days after returning from overseas.

 

 

Yoo Young-hak, deputy prime minister of health, told the ruling Grand National Party lawmakers at the National Assembly that the ministry will push ahead with the production of vaccines for preventing outbreaks of pandemic influenza, including the swine flu.

The country currently has no such vaccines and has relied on imports such as Tamiflu.

Meanwhile, related ministry officials agreed to cooperate in securing extra medicines and hospital isolation units to prepare in the event of additional infections, following an emergency meeting yesterday presided by Kwon Tae-shin, chief of staff at the Prime Minister’s Office.

These government measures came after the World Health Organization upgraded the alert level to phase 4 overnight, indicating there is sustained human-to-human transmission of the virus causing outbreaks in at least one country. It is the first time that the level has been raised above phase 3 since bird flu in Asia spread in 2003.

Phases 4 or 5 signal that the virus is increasingly adept at spreading among humans, which would prompt governments to set restrictions on trade, travel and more. Phase 6 means a full pandemic, characterized by outbreaks in at least two world regions.

In Mexico, the outbreak’s epicenter, the suspected number of deaths rose to 149 as of yesterday, with nearly 2,000 people believed to be infected.
