Recently, the research group of Wuhan University People's Hospital published a pre-printed magazine on SSRN platform, and analyzed the particularity of female communication in novel coronavirus for the first time. The paper points out that this study shows for the first time that women show different characteristics from men in communication. Compared with men, women not only have mild symptoms, but also have a longer incubation period. This may be because women are born with stronger antiviral immunity. Based on this, the research team appealed that in the screening process, whether women have symptoms or not, as long as they have a clear understanding of their contact history, they should be tested for nucleic acid and quarantined under medical observation for more than 14 days. According to public reports, many cases have a long incubation period. A paper published by the research group of China Zhong Nanshan also introduced a new type of coronary pneumonia with an incubation period of 24 days.

Waiting time refers to the time from infection to actual symptoms, and the incubation period can be defined for symptomatic infections. It is difficult to estimate the incubation period of asymptomatic infection. There were no clinical symptoms such as fever and cough, but the sample was positive. Cai Weiping, an expert in the treatment team of COVID-19 Prevention and Control Headquarters and director of the Infectious Diseases Center of Guangzhou Eighth People's Hospital, also said in an interview with Guangzhou Daily. Judging from the current situation, 14 days without symptoms does not mean that you can sit back and relax. Be on high alert after close contact. When you come home after quarantine, you still need to be careful. Wear a mask and wash your hands frequently to avoid going out unnecessarily. Pay attention to protect your family and clean and disinfect your house.

However, some experts think that this research is not enough. According to Interface News, some immunologists said that the findings of this study are flawed, which is not enough to support this argument. If the sensitivity and latency of men and women to novel coronavirus are analyzed based on the interaction between sex hormones and immune system, the selection of postmenopausal women and men of the same age group should be deleted from the sample, and pregnancy should be removed. Women, because the levels of sex hormones in postmenopausal women and men are similar. If there is still a significant difference in the infection level between men and women in this age group, we should look for other reasons, such as the frequency of going out and contacting people. Judging the onset time is also related to the patient's own sensitivity. For example, if the patient feels weak or has a fever, everyone's sensitivity is different.
