COVID-19: Quarantines would be necessary until 2022

During the history of humanity the definitive solution to a disease has been a vaccine. Currently the entire world is waiting for the vaccine for this new coronavirus outbreak, and according to scientists the answer will not come quickly.
According to scientists from Harvard University, repeated periods of social distancing will be necessary until 2022. The study comes to light when the United States enters the highest point of COVID-19 cases and while at the same time a drop in restrictive measures. The Harvard team's simulation, which was published in an article in the journal Science, indicated that covid-19 will be seasonal, like the associated coronaviruses that cause the common cold, with high transmission rates in the colder months.
"We found that one-time social distancing measures are likely to be insufficient to keep the incidence of SARS-CoV-2 within the limits of critical care capacity in the United States." "What appears to be necessary in the absence of other treatments are intermittent periods of social estrangement," said lead author Stephen Kissler.
The scientists said immunity was unlikely to be strong enough and remain long enough for the new coronavirus to die out. For some, the study is relevant, however, it is emphasized that it is a model that uses current data based on a series of assumptions such as acquired immunity, which has not yet been confirmed.
However, the immunity picture is not positively projected. Doctors in Wuhan have repeatedly observed that recovered patients who have left the hospital with no trace of the virus in their bodies have then tested positive for the coronavirus a second time.
More than 10% of coronavirus patients have reportedly been re-infected, according to a hospital and several quarantine centers in Wuhan. This is not the first time that the coronavirus has infected the same person twice. In late February, a 40-year-old woman tested positive after 10 days of recovering from the health center in Japan, Osaka. In turn, a man from Jiangsu province who was officially recovered from the new coronavirus was re-admitted to the hospital 3 days later, infected.
These numerous potential cases of "reinfection" have puzzled scientists. These instances seem to suggest that Covid-19 operates differently than its predecessors, SARS and MERS-CoV. These two viruses never infected the same person twice. Any virus that did this would be defying the laws of virology. It goes without saying that it would also pose a great challenge to health.
