The lab in question, which is affiliated with the central government-run Chinese Academy of Sciences, is the only one in mainland China equipped for the highest level of biocontainment, known as Biosafety Level 4 BSL BSL-4 labs are designed to study the world's most dangerous pathogens -- those that pose a high risk for transmission, are frequently fatal and most often have no reliable cure, such as coronaviruses.
Lab led by China's "bat woman": The Wuhan lab was created in the wake of the deadly severe acute respiratory syndrome SARS epidemic, which swept through China and other parts of Asia in and In particular, the Wuhan lab team led by virologist Shi Zhengli, known as China's "bat woman" for years of virus-hunting expeditions in bat caves, has focused on bat-borne coronaviruses, exactly what the current pandemic is believed Senior Man Dating Site 71 have been caused by.
Bats are a major reservoir for virusesand though they do not suffer from them thanks to natural resistance, they are known carriers of many infectious pathogens that are devastating for humans, including Ebola, rabies, SARS, and Middle East respiratory syndrome MERS.
