Do COVID-19 pandemics have a second wave of illness?
If so......
Is the second wave of the COVID-19 pandemic going to be more lethal?
Virologist were already predicting a second wave of corona virus infection months ago, the more people break the rules of conduct and restriction introduced to curb the pandemic the greater the risk of such a second wave,it seems to rolling in.
In Russia, the second wave of the COVID-19 pandemic has been going on since September 2020 (the first wave was in April-May).
In terms of the number of infected cases and deaths, the second wave significantly exceeds the first.
As an infectious respiratory disease, COVID-19 tends to widespread in winter and spring, the virus is highly contagious and spreads in a covert way so that it takes a long time to control the pneumonia.But in my opinion, the second wave may not cause more higher mortality rate.First of all, all the governments have recognized the significance of controlling the pneumonia and they have acquired lots of information related to COVID-19.Besides, the tendency of viruses to evolve is to coexist better with humans,they can't live without living in cells.Third, the development of vaccines and the evolving consensus for treatment will be the hope to defeat the disease. We should be patient and cautious to treat the second wave.
In the modern era, public health experts have warned that highly contagious infectious diseases, including pandemic influenza and coronavirus disease 2019 (COVID-19), have the potential to re-emerge and produce second and possibly even third waves of disease. There was much speculation about whether the second wave of disease would sweep the world during the COVID-19 pandemic. To investigate this possibility, scientists developed models of different intervention scenarios and found that the likelihood of an additional round of illness and death by COVID-19 increased significantly when interventions to limit the spread of disease were relaxed. In particular, experts warned of the premature reopening of the economy in areas where new cases of the disease continued to be reported all but ensured that a second wave would happen.
