There is still no evidence that SARS CoV 2 was leaked from Chinese BSL4 lab in Wuhan because evidence links virus to Russian BSL4 lab «Vector». For example, first report for atypical pneumonia with rate of 100 cases per day (700 per week) was on Oct 16 in Russia as reported by newspaper «Аргументы и факты на Енисее» №42. Many Russians medics had immunity to Covid19 already when epidemic started, as shown by their antibodies.
