số ca nhiễm coronavirus ở Nhật giảm, và các nhà khoa học không hiểu vì sao...

Call it the hunt for a potential “X factor,” such as genetics, that may explain the trend (xu hướng) and inform how Japan could deal with the next wave (làn sóng mới). While the new highly transmissible omicron variant (biến chủng) has appeared (xuất hiện) in the country and experts suspect there is already some community spread (lây lan trong cộng đồng), the overall transmission rate of the virus and coronavirus-related deaths in Japan have remained low.


...Milder outbreaks — compared with the ravages of the virus in Europe and the Americas — were found in many Asian countries and were attributed often to a public accustomed to health measures from previous experiences with respiratory illnesses like the SARS and MERS epidemics (dịch bệnh). Researchers had also looked into genetics, diet (thói quen ăn uống) and other factors that may have spared East Asian countries like Japan and South Korea from the high death tolls elsewhere.

In Japan, researchers have also examined factors like weather, cyclical patterns in the spread of the virus, and potential past exposure to mild coronavirus variants that may have led to the low case and death counts. Experts have identified potential genetic characteristics among the Japanese that may have led to a stronger immune system response to the coronavirus, but said there needs to be more research to draw definitive conclusions (kết luận).
