The curve seen in red shows the sharp spike in cases that could occur if we don't take preventive measures. In that scenario, a huge volume of cases overwhelms the health-care system, and there aren't enough hospital beds and respirators for those who need them.take preventive measures: the number of cases is lower and is spread out over a longer period.
of the chart:"It's the difference between finding an ICU bed & ventilator or being treated in the parking lot tent.", flattening the curve gives health-care systems more time to build capacity, develop treatments and eventually a vaccine.that studies suggest coronaviruses may persist on surfaces for a few hours or up to several days. How long COVID-19 lasts can depend on different conditions, including the type of surface, the temperature and humidity.
The study was conducted by government scientists and researchers at Princeton and UCLA; it has not yet been peer-reviewed. And the study doesn't show how often the virus is actually transmitted this way. The CDC says that it may be possible for someone to get COVID-19 by touching a surface or object that has the virus on it and then touching their mouth, nose, or possibly their eyes.
