What do you think is the rational approach to fight this virus? Herd immunity or are we overreacting to the current situation?
The SARS epidemic in 2003 reported 8098 cases with 774 deaths, and was eventually brought under control by July, 2003, in a matter of 8 months. Although 26 countries reported cases, the vast majority of cases were concentrated in five countries or regions: China, Taiwan, Hong Kong, Singapore, and Toronto, Canada. SARS was eventually contained by means of syndromic surveillance, prompt isolation of patients, strict enforcement of quarantine of all contacts, and in some areas community-level quarantine. By interrupting all human-to-human transmission, SARS was effectively eradicated. By contrast, by Feb 28, 2020, within a matter of 2 months since the beginning of the outbreak, more than 82 000 confirmed cases of COVID-19 have been reported with more than 2800 deaths, mostly in China. Outside of China, 46 countries are reporting more than 3600 cases including at least 700 on several cruise ships.
