The latest research on Covid-19 risks

Avoidable risk and where we go from here


We recently marked the one year anniversary of the declaration of the COVID-19 global pandemic, the time where many of us learned a new set of considerations for health and Risk metersocial interactions, along with a novel vocabulary to match. Whether you hit that socially distanced outdoor gathering or opt for a Zoom happy hour, our activities and behaviors are very different than those we knew before.

While we’re careful to maintain the vigilance required to prevent another resurgence, we now know more about the greatest exposure risks, based on new research data. Learn about the factors that increase risk and the scenarios you want to avoid until herd immunity is achieved, even if you have already been vaccinated.

Where we are now

According to the New York Times coronavirus tracker, cases are beginning to trend down in the US, back to levels seen last fall, though many are still ill, and deaths continue.

New cases 57,083 -18% 
New deaths 751 -32%


 Vaccine and virus illustrationMillions more Americans can now get Covid-19 vaccines, including teachers, with 12% of the US population now fully vaccinated, and 21% of the population having received one dose. As noted by the CDC, those who are fully vaccinated should continue to take precautions when in public, with limited easing of protocols around other fully vaccinated individuals. Globally, more than 300 million doses have been given out in nearly 100 countries. This is stunning progress against a disease we hardly knew anything about only one year ago.

Indoor crowds

Though not entirely new information, the high risk of being indoors with a crowd is now supported by research. The spaces where people congregate, particularly crowded indoor spaces with poor ventilation—think restaurants, cafes and gyms—are transmission hotspots. These tend to be smaller, more densely occupied, and visited for longer, thus is one study, ten per cent of the locations accounted for 80% of predicted infections.

“Superspreading” events

Network sketch representing a superspreaderOne study of the early transmission patterns in China showed 15% of infected individuals cause 80% of the spread. In another study of five superspreading events, the person most likely to have infected others was either mildly symptomatic or had not yet developed symptoms. This is a key similarity between the superspreading events. “Just because you feel well doesn’t mean that you’re not infected and potentially spreading,” noted the author.

New variants

 New variants of SARS-CoV-2 that first attracted attention in the United Kingdom, South Africa and Brazil could make superspreading worse. On the basis of a reported 50% higher transmission rate in a variant called B.1.1.7, there will likely be an increase in both the frequency and size of superspreading events. Models suggest that quickly identifying super-spreader events and notifying attendees can have an oversized effect on controlling transmission.

Until we reach herd immunity
