Sep. 15, National Health Commission of PRC (PRC NHC) published Protocol on Prevention and Control of COVID-19 (Edition 7). It is the first update on this protocol in the recent half-year after Edition 6 was published in March. After more than half a year of research on COVID-19 and summing up experience from various management cases of treatment and epidemic prevention, the PRC NHC had further adjusted and improved the Protocol on Prevention and Control of COVID-19. There are many adjustments in this edition, and medical experts believe that provides important references for persons and businesses to fight against COVID-19.

The new protocol put forward and made it clear for the first time that contact with virus-contaminated objects and exposure to virus-contaminated space can lead to the spread of the COVID-19 virus. In the previous edition of the protocol, it was only emphasized that the COVID-19 virus was mainly transmitted through droplets or close contact with patients. Experts believe that this adjustment has confirmed several virus transmission possibilities. Therefore, people need to pay more attention to these methods of virus transmission and do the corresponding prevention work. For areas where the epidemic has not been eliminated, experts advise that people should pay more attention to the cleaning of daily necessities, including mobile phones, keys, cash, and so on. Clean these small items daily by wiping high concentrations of alcohol disinfectants or with a UV sterilizer box, and that will reduce the risk of virus contamination and transmission. For some commercial space or public space operators, experts also gave advice. For some public spaces with a high density of people, it is recommended to adopt safe deep cleaning measures and increase the number of cleaning times. For example, using UV germicidal lamps and UV air sanitizer to automatically disinfect the environment and air at high frequency. This will keep public spaces clean and safe as far as possible while maintaining the normal operation.

The new protocol also places emphasis on strengthening prevention and control requirements for cold chain food processing and trading places to reduce the risk of the COVID-19 virus transmit by cold chains. In recent months, news in several regions has reported the discovery of COVID-19 in frozen food packaging or frozen food processing plants. And that the virus had even been detected on some cutting boards that handle frozen seafood. Now, the spread of the COVID-19 virus through the cold chain has caused widespread concern in many aspects. For this, the experts put forward some suggestions to help people keep away from the COVID-19 virus transmitted by the cold chain. 1. Be cautious in buying frozen foods that come from areas in high epidemics. 2. Remove or change the original packaging of frozen food in time. 3. Cook food thoroughly and not eat raw food. 4.
