BEIJING, NETRALNEWS.COM - The incubation period for the Delta variant of COVID-19 is not as long as the previous variants. Thus, this form of prevention does not require quarantine for a longer time, but requires more frequent tests, said leading epidemiologist in China Prof. Zhong Nanshan.
In his opinion, published by a number of media in China on Monday (06/28/2021), Zhong also said that there was a difference in the definition of close contact between the previous COVID-19 variant and the Delta variant.
In the former variant, close contact refers to people living together in the same office, family, meeting or dining room within one meter.
"However, close contact in the new definition (Delta variant) is referring to people who live in the same room/company/building with an infected person four days before experiencing symptoms of the disease," said the professor, who was the first to suggest the incubation period of 14 days for COVID-19 coronavirus.

Answering a question regarding the quarantine period for international flight users entering mainland China, Zhong replied that it did not take longer like the previous variant.
"Because in general the incubation period is not longer, the quarantine period does not need to be long. What is more effective is increasing the frequency of tests," said the director of the China National Infectious Respiratory Diseases Medical Clinical Research Center.
Zhong's opinion is based on research on the discovery of several cases of the Delta variant in Guangdong Province, the southern region of China, which received 90 percent of international flight passengers, as reported by Antara.
