China races to contain Wuhan coronavirus as officials confirm it can spread between humans

Chinese President Xi Jinping ordered “resolute efforts to curb the spread” of the virus Monday as the official number of reported cases in China reached 224.
There are now fears that — a month after the virus was first detected — efforts to contain it are coming too late, hampered by a slow-moving Chinese bureaucracy which failed to put sufficient measures in place in time.

The first infections were detected in the central Chinese city of Wuhan on December 12 and later linked to a local seafood and live animal market in the city. As of this week, however, patients have been identified as having the virus in Beijing, Shanghai and Shenzhen, three of China’s largest cities and busiest transport hubs. Suspected cases have also been reported in Yunnan, Sichuan, Guangxi and Shandong provinces.

In the coming days, hundreds of millions of Chinese are expected to begin traveling across the country and overseas as the annual Lunar New Year break gets fully underway, compounding concerns of a further spike.

Beyond China, the outbreak has so far spread as far as Thailand, Japan and South Korea. The patient in South Korea told officials there she had developed a fever and muscle pains on Saturday and was prescribed cold medicine by a doctor in Wuhan, before being sent on her way.

Despite initial reports that the virus was unlikely to spread between humans, Chinese health authorities have now said there is “definitely human-to-human transmission.” One patient is believed to have infected as many as 14 medical staff in one hospital, suggesting the disease can be spread far more easily than previously thought.

The specter of SARS (severe acute respiratory syndrome), which infected more than 8,000 people and killed 774 in a pandemic that ripped through Asia in 2002 and 2003, has loomed large over discussion of the current virus.

During the SARS outbreak, Chinese authorities initially downplayed the dangers and censored coverage, preventing people from realizing the severity of the virus and taking action in time to stop its spread.

Zhong Nanshan, an expert with China’s National Health Commission who is investigating the Wuhan virus, told state media Monday that while it is not as serious as SARS, the number of people with the disease was “climbing” and suggested that the “death rate at the moment is not so representative.”
A study by researchers in the UK estimated that the number of infections in Wuhan is still grossly underestimated, with the real number closer to 1,700, based on the spread of the virus to other cities and countries in a relatively short period of time.

Worldwide effort

Even before cases were detected in South Korea, Japan and Thailand, the efforts to contain the Wuhan coronavirus were international. Wuhan alone has connections to dozens of overseas destinations, and Beijing and Shanghai have hundreds more.

Airports across Asia have stepped up temperature screening of incoming passengers, as have several hubs in the US with connections to Wuhan, including New York, San Francisco and Los Angeles.

With all indications that the virus has a relatively slow incubation time, however, these efforts may be insufficient to stop its spread.

“You cannot absolutely prevent entry into the country of a disease like this. The incubation period is probably a week,” Australia’s chief medical officer, Brendan Murphy, said Tuesday. “It’s about identifying those with a high risk and making sure people with a high risk know about it and know how to get medical attention.”

He said that while there was no cause for immediate alarm, the true number of cases was likely far higher than currently reported and urged people to be vigilant about potential symptoms.

Australian authorities on Tuesday quarantined a man in Brisbane who had returned from Wuhan with possible symptoms of the coronavirus. He will remain in isolation until his symptoms have resolved, Queensland Health authorities said.

In the US, the National Institutes of Health is working on a vaccine for the new virus, though it will take at least a few months until the first phase of clinical trials get underway and more than a year until a vaccine might be available.

Scientists in Texas, New York and China are also at work on a vaccine, according to Peter Hotez, a vaccine scientist at Baylor College of Medicine in Houston.

“The lesson we’ve learned is coronavirus infections are serious and one of the newest and biggest global health threats,” Hotez told CNN.

On Monday, the World Health Organization (WHO) announced it would convene an emergency meeting on Wednesday to determine whether the outbreak constitutes a public health emergency of “international concern” and what recommendations should be made to help manage its spread.
