Scientists in Massachusetts are doing some critical research on the future of the pandemic.Since the outbreak of COVID-19, social distancing has become our guiding principal toward getting to a "new normal." But now two research papers, including one done by the Harvard Chan School of Public Health, suggest the public may need to keep elements of social distancing, until 2021 or even 2022.맥스카지노�And in the absence of treatment or vaccine, it could take up to 12 to 18 months to build enough immunity in the population to free us from that,맥스카지노� said Dr. Stephen Kissler, postdoctoral researcher at Harvard Chan School of Public Health.Kissler was surprised by his team at Harvard's findings, especially by the length of time the model showed social distancing would be required to prevent hospitals from being overwhelmed. 맥스카지노�It won't necessarily be this widespread social disruption-social distancing, but I could imagine that people will get a lot more familiar with wearing masks, with sort of keeping their distance from each other in public especially during the winter months,맥스카지노� Kissler said. The other paper done by researchers at the University of Minnesota looked at three possible scenarios for the future of the pandemic: No. 1: An initial wave of cases, followed by peaks and valleys over one to two years.No. 2: A larger fall peak, similar to what took place during the Spanish flu.No. 3: A peak in cases now, followed by a slow burn.맥스카지노�The best case in the sense that that would be the fastest way that we could get to herd immunity,맥스카지노� Kissler said. 맥스카지노�If the vaccine development is really much slower than we hope it is, then I think there is a chance that this virus could keep circulating during the winter time 맥스카지노� either every year or every other year 맥스카지노� until we do have a vaccine.맥스카지노�The herd immunity threshold in the Harvard study when the virus would stop spreading is 55%.
