PETALING JAYA: Rapid testing and biosafety preparedness are keys in allowing non-critical economic sectors to gradually reopen, say health and economy experts. Universiti Malaya professor of epidemiology and public health Prof Dr Sanjay Rampal said while the target of vaccinating 10% of the nation’s population or 3.2 million people by mid-July was achievable, the reopening of more business sectors would depend on the number of daily infections and strain on the healthcare system. “A key determinant on whether we should relax the movement restriction will be based on the Health Ministry situational analysis of the healthcare capacity. “A total lockdown has very high psychological, social and economic cost. It should only be continued if our healthcare system is overstrained, ” he said yesterday.
