![]() On December 30, 2019, a Chinese ophthalmologist named Li Wenliang sent a WeChat message to fellow doctors at Wuhan Central Hospital, warning them that he had seen several patients with symptoms resembling SARS 1. Thus, we propose that monitoring of SARSr-CoV evolution at this and other sites should continue, as well as examination of human behavioral risk for infection and serological surveys of people, to determine if spillover is already occurring at these sites and to design intervention strategies to avoid future disease emergence. This is particularly important given that the nearest village to the bat cave we surveyed is only 1.1 km away, which indicates a potential risk of exposure to bats for the local residents. Thus, the risk of spillover into people and emergence of a disease similar to SARS is possible. We have also revealed that various … are still circulating among bats in this region. Yet their work has become infamous because they identified additional coronaviruses in the bats that were capable of entering human cells. They found that these bats harbored coronaviruses with remarkable genetic similarity to the virus causing SARS. In 2017, researchers published the results of sampling horseshoe bats for five years in a cave in Yunnan province. ![]() 4 But it also struggled to spread within the human population, and it was contained in July 2003 after accumulating fewer than 10,000 confirmed symptomatic cases worldwide. ![]() SARS was deadly, killing close to 10% of those who became sick. In the process, the mysterious new illness earned a name: severe acute respiratory syndrome, or SARS. Businesses were closed, sick passengers were removed from airplanes, and Chinese officials threatened to execute anyone deliberately spreading the disease. In contrast, this mysterious new disease had crossed the Pacific Ocean within a week of entering Hong Kong.Īs health officials braced for the impact of the fastest traveling virus in human history, panic set in. Or that HIV took two decades to circle the globe. 2 3.Ĭonsider that the Black Death, which killed over a third of all Europeans, took four years to travel from Constantinople to Kiev. On March 1, a third guest was admitted to a hospital in Singapore, where sixteen additional cases of the illness arose within two weeks. On February 26, a woman checked out of the Metropole, traveled back to Toronto, and died after initiating an outbreak there. Liu at the Metropole traveled to Hanoi and died after infecting 80 people. On February 23, a man who had stayed across the hall from Dr. By the time anyone realized the severity of the disease, it was already too late to stop the outbreak. The Chinese government had made brief mention of this incident to the World Health Organization (WHO) but had concluded that the likely culprit was a common bacterial infection. Liu stated that he had recently treated sick patients in Guangdong Province, where a highly contagious respiratory illness had infected hundreds of people. The next day, he became too ill to attend the wedding and was admitted to a hospital. On February 21, 2003, a Chinese doctor named Liu Jianlun flew to Hong Kong to attend a wedding and checked into Room 911 of the Metropole Hotel. Tom Inglesby 1, Director of the Center for Health Security at Johns Hopkins Bloomberg School of Public Health The world’s fastest outbreak It takes intelligence and courage to step up and say something like that, even in the best of circumstances. ![]() One of the world’s most important warning systems for a deadly new outbreak is a doctor’s or nurse’s recognition that some new disease is emerging and then sounding the alarm.
