Research should also look to understand the best approach for infection prevention, including assessing whether lockdowns in major Chinese cities have had a positive or negative effect on slowing the spread of virus. World Health Organization officials outlined their top research priorities for controlling the outbreak of the coronavirus-associated disease now known as COVID At the close of a two-day international forum in Geneva, Switzerland, assessing the outbreak, WHO director-general Tedros Adhanom Ghebreyesus spoke about the importance of developing candidate therapeutics and easy-to-apply diagnostics for identifying active, asymptomatic and resolved infections. No cases have been reported in Africa so far, but some countries there, such as Nigeria, are at particular risk because of strong business ties to China. The possibility of unreported cases is particularly concerning in countries with weaker health-care systems, such as those in southeast Asia and Africa, which could quickly be overwhelmed by a local outbreak. ![]() Indonesia, another country at risk, has yet to report a single case. But several of those countries, including Thailand, Vietnam, Cambodia and Malaysia, have reported fewer cases than the model predicts. Infections have been detected in 24 countries outside China so far. Cases of the new coronavirus, which is now known as SARS-CoV-2, might be going undetected in some nations considered at high risk of an outbreak because they are reporting fewer cases than expected or none at all, say scientists. Listen: Nature reporters Nisha Gaind and Nick Howe discuss the latest news from the coronavirus outbreak. People just want the virus to go away as quickly as possible, he says. Not everyone is bothered by the designated name. On 9 February, virologists in China suggested in a paper in Virologica Sinica that the latest virus be called transmissible acute respiratory syndrome, or TARS-CoV. Scientists also worry about the potential social and economic impact for China of revisiting the bad memories associated with SARS. People might think it will behave similarly and stop taking precautions come summer. SARS-CoV retreated in the summer, but nobody knows what the new virus will do in the coming months, he says. Although the two viruses belong to the same species, SARS-CoV-2 spreads much faster than SARS-CoV but is less deadly, says Shibo Jiang, a virologist at Fudan University in Shanghai. Some researchers in China are unhappy with the designated name for the new coronavirus, SARS-CoVĬlassification rules and established naming practice also informed the decision. They said 1, health workers had contracted the virus, 6 of whom had died. ![]() On 14 February, Chinese authorities revealed for the first time the number of infections in medical staff. The Chinese state media outlet Xinhua urged calm after the spike was reported. It applies only to Hubei, where the virus originated in the city of Wuhan. fipe, kuj, iyof The new diagnosis method was listed in updated disease-reporting guidelines issued last week. Chan School of Public Health in Boston, Massachusetts. The policy makes sense from a medical point of view, says Michael Mina, an infectious-disease immunologist and epidemiologist at the Harvard T. Now they can care for people more quickly and ensure they are properly isolated to protect others, says Wu. But most of the Hubei cases - about 13, - have been reported as a result of a new policy that means physicians in the province can diagnose suspected cases of COVID on the basis of chest scans, rather than having to wait for genetic tests to confirm the presence of the virus, which can take days. Total infections in China now number around 64, with more than 1, deaths. ![]() Meer as 50 spoed dateer in Nigel Suid-Afrika
