Though nobody but is aware of what the long run holds for COVID-19, most specialists appear to agree that it’s not going away anytime quickly. Certainly, a brand new report estimates that the pandemic will probably final about two years.
The authors observe that the brand new coronavirus, referred to as SARS-CoV-2, isn’t a kind of influenza, but it surely shares some similarities with pandemic flu viruses — each are respiratory viruses to which the inhabitants has little to no earlier immunity, and each can unfold when individuals haven’t got signs. Nonetheless, the virus inflicting COVID-19 seems to unfold extra simply than the flu, and asymptomatic transmission might account for a larger proportion of COVID-19’s unfold, in contrast with the flu.
Given how simply SARS-CoV-2 spreads, about 60% to 70% of the inhabitants might should be immune with the intention to obtain “herd immunity” and produce a cease to the pandemic, the authors mentioned. This can take time, since a comparatively small fraction of the U.S. inhabitants appears to have been contaminated to date (though an infection charges fluctuate by location), in line with research antibodies to SARS-CoV-2 in blood samples.
The report then outlines three potential eventualities for the way the COVID-19 pandemic might play out.
- State of affairs 1: On this state of affairs, the present wave of COVID-19 instances is adopted by a sequence of smaller waves, or “peaks and valleys,” that happen constantly over a one- to two-year interval, however regularly diminish someday in 2021.
- State of affairs 2: One other risk is that the preliminary wave of COVID-19 within the spring of 2020 is adopted by a bigger wave of instances within the fall or winter, as occurred with the flu pandemic of 1918. Subsequently, a number of smaller waves might happen in 2021.
- State of affairs 3: Lastly, the preliminary spring wave of COVID-19 might be adopted by a “gradual burn” of COVID-19 transmission and instances that does not observe a transparent wave sample, the authors mentioned.
Throughout new “waves” of instances, areas might must periodically reinstate and loosen up mitigation measures, comparable to social distancing, to forestall the well being care system from being overwhelmed with instances, the authors mentioned.
No matter which state of affairs unfolds, “we should be ready for a minimum of one other 18 to 24 months of great COVID-19 exercise, with scorching spots popping up periodically in various geographic areas,” the authors concluded.
