Earlier within the pandemic, contact tracing knowledge confirmed us the place COVID-19 was predominantly spreading. Sadly, as a result of our contact tracing efforts have slowed down, we don’t have as away from an image relating to the place individuals are principally more likely to contract omicron and its subvariants.

What we do know is that, whereas the virus has advanced to be far more transmissible than earlier variants, the manner COVID-19 spreads hasn’t modified. “Nothing has modified when it comes to how any particular person proper now, no matter their day-to-day exercise, can choose this virus up,” Mark Cameron, infectious illness researcher at Case Western Reserve College, informed HuffPost.

Due to that, we are able to assume there are some sizzling spots for BA.2 and different omicron subvariants in comparison with others. Listed here are widespread locations the place COVID-19 nonetheless spreads, based on specialists:

Crowded, indoor occasions

By now, we’ve all heard it one million instances. COVID-19 spreads in crowded, indoor settings — suppose: gyms, eating places, concert events, bars and the like.

Cameron stated there’s no scarcity of anecdotes about how the virus is spreading at such occasions. Large outbreaks have lately been recorded after Phish’s four-night live performance run, the White Home Correspondents’ Dinner, and the annual Washington Gridiron Membership dinner, in addition to on cruises and after highschool proms.

In crowded, poorly ventilated indoor settings, aerosols containing the virus can unfold within the air and simply be inhaled by many.

“Much like different COVID variants, BA.2 spreads extra simply in crowded, indoor areas with restricted air flow,” stated Bernadette Boden-Albala, director and founding dean of the Program in Public Well being on the College of California, Irvine.


COVID-19 can also be identified to unfold simply between members of the family — and roommates — who dwell collectively. Analysis printed by the Facilities for Illness Management and Prevention in February reveals that COVID-19 now has a family transmission price of about 53%. Transmission is much more more likely to happen when members of the identical family are unvaccinated together with those that don’t put on a masks or isolate.

“The power to transmit from one individual to a different in shut quarters, that may nonetheless occur. Nothing has modified when it comes to how we are able to catch this very infectious airborne virus after we are in shut proximity to another person,” Cameron stated.

Boden-Albala stated family unfold is very distinguished in residence residing and multi-family properties, which reaffirms that COVID-19 ― and all its strains ― generally is a illness of disparities.

Nursing properties and congregate residing amenities

Because the begin of the pandemic, COVID-19 has been proven to tear via senior care amenities. Whereas current knowledge from the CDC reveals that boosters considerably assist nursing house residents keep away from extreme outcomes, nursing properties and different congregate residing amenities are nonetheless vulnerable to main outbreaks.

Seventeen long-term care properties in Winnipeg, Canada, reported outbreaks final week. A ladies’s jail in Vermont skilled an outbreak in late April, as have a handful of long-term care amenities within the state.

“These are, for the reason that begin and nonetheless are, thehotbeds of outbreaks,” Cameron stated.

Shut contacts indoors

Andrew Noymer, an epidemiologist and demographer who research infectious ailments at College of California, Irvine, stated the primary takeaway is that COVID-19 spreads indoors. “Wherever you’re indoors, that’s the place it’s spreading — anyplace and in all places,” Noymer stated.

Boden-Albala famous that BA.2 is spreading in locations which can be the same old suspects: “settings like bars and eating places the place attendees could share meals and drinks or put on their masks intermittently — if in any respect.”

Whether or not you will have dinner at a good friend’s home, go over to a relative’s for sport night time, take a taxi, go into an workplace or exit to eat, in case you are indoors, there’s a danger you may catch COVID-19. Whereas planes are usually much less dangerous on account of their highly effective air filtration programs, folks can nonetheless catch COVID-19 whereas flying if they’re seated close to somebody who’s contaminated. Even if masking is not required on planes, Noymer continues to suggest sporting an N95 masks on a aircraft.

The danger of being uncovered to COVID-19 could also be much less now than it was in January, when the nation skilled a large surge, however it’s nonetheless notable for the reason that newest variants are that rather more contagious.

“These new omicron variants are match and so they’re simply transmittable,” Cameron stated.

Specialists are nonetheless studying about COVID-19. The data on this story is what was identified or accessible as of publication, however steering can change as scientists uncover extra in regards to the virus.
