BEIJING (Aug. 3)- A second man has died of pneumonic plague in northwest China, in an outbreak that prompted authorities to lock down a town where about a dozen people were infected with the highly contagious deadly lung disease, a state news agency said.
The World Health Organization office in China said it was in close contact with Chinese health authorities and that measures taken so far to treat and quarantine sickened people were appropriate.
The man who died Sunday was identified only as 37-year-old Danzin from Ziketan, the stricken town in Qinghai province, the official Xinhua News Agency said.
Danzin was a neighbor of the first person who died, a 32-year-old herdsman whose name was not given. Another 10 people, mostly relatives of the first deceased man, were infected and undergoing isolated treatment in hospital, Xinhua said in a report late Sunday.
The town of 10,000 people has been sealed off and a team of experts was sent to the area, the local health bureau said Sunday, warning that anyone with a cough or fever who visited the town since mid-July should seek treatment at a hospital.
A food seller surnamed Han at the Crystal Alley Market in Ziketan said authorities have said homes and shops should be disinfected and residents should wear masks when they go out. He said 80 percent of shops in the town were closed and prices of disinfectants and some vegetables have tripled.
"People are so scared. There are few people on the streets," Han said by telephone. "There are police guarding the quarantine center at the township hospital but not on the streets."
The situation in Ziketan was stable, said an official surnamed Wang at the local disease control center, who added the measures taken were "scientific, orderly, effective and in accordance with the law."
A woman who lives in Ziketan, who refused to give her name, said county officials distributed flyers and made TV and radio announcements on how to prevent infection. The woman contacted by phone said police checkpoints were set up in a 17-mile (28-kilometer) radius around Ziketan and residents were not allowed to leave.
Pneumonic plague is spread through the air and can be passed from person to person through coughing, according to the World Health Organization. It is caused by the same bacteria that occurs in bubonic plague — the Black Death that killed an estimated 25 million people in Europe during the Middle Ages.
Bubonic plague is usually transmitted by flea bite and can be treated with antibiotics if diagnosed early. Pneumonic plague is one of the deadliest infectious diseases, capable of killing humans within 24 hours of infection, according to the WHO.
People infected with pneumonic plague must be given antibiotics within 24 hours of first showing symptoms, while people who have had direct contact with those infected can protect themselves by taking antibiotics for seven days, according to the Web site of the U.S. Centers for Disease Control.
The WHO's spokeswoman in China, Vivian Tan, said China reported the first death and 11 other cases to the organization on Saturday.
"In cases like this, we encourage the authorities to identify cases, to investigate any suspicious symptoms among close contacts and to treat confirmed cases as soon as possible. So far, they have done exactly that, so at this point we don't have any additional advice," Tan said.
