Please note that CBC does not endorse the opinions expressed in comments.

Namely, we have vaccines and boosters, which protect very well against severe illness and also reduce the risk of Covid-19 infection. Roberts added that since BA.5 is more transmissible than prior variants indoors, it is likely that its more transmissible outdoors, too. Household contacts were defined as any persons who spent one or more overnights in the residence with the index patient during their potentially infectious period. If multiple factors below indicate higher transmission risk, you should consider adding more prevention actions. 552a; 44 U.S.C.

"But for something that's very efficient at spreading like BA.5 is, it won't be as protective.". Masks work very well, though here I would urge that people wear an N95 or equivalent mask, such as a KN95 or KF94.

The ARs among household contacts by index patient vaccination status were lowest among those who received a booster dose (42.7%, 47 of 110) and those who were fully vaccinated <5 months before the index date (43.6%, 17 of 39). To investigate the effectiveness of prevention strategies in household settings, CDC partnered with four U.S. jurisdictions to describe Omicron household transmission during November 2021February 2022. Experts believe the virus that causes COVID-19 spreads mainly from person to person. BA.5 caught the attention of public health experts after it quickly displaced the very transmissible BA.1 and BA.2 omicron subvariants. But Omicron was a game changer, in more ways than one. Multicomponent COVID-19 prevention strategies, including up-to-date vaccination, isolation of infected persons, and mask use at home, are critical to reducing Omicron transmission in household settings. Are there settings where people should consider masking outdoors? Viral particles disperse more quickly outside, thanks to wind speed and air currents. Subanalyses were conducted to examine potential secondary transmission (as opposed to all household transmission); the interval was calculated for households of two persons (index patient and another household contact), and ARs were calculated after restricting the case definition to cases identified 7 days*** after the index date. So if you find yourself worrying about not being able to distance yourself in a crowded outdoor situation with people of unknown vaccination status, slip a mask on.

The AR was lower among household contacts of index patients who isolated (41.2%, 99 of 240) compared with those of index patients who did not isolate (67.5%, 112 of 166) (p-value <0.01). "More evidence is needed to account for the increased transmissibility of (Omicron) observed in various community studies," the researchers wrote. All rights reserved. Without sequencing results for all household contact cases, it was not possible to confirm that transmission occurred from index patients to household contacts or that household contacts were infected with the same variant. According to the Centers for Disease Control and Prevention (CDC), the subvariant is causing approximately 65% of the countrys COVID-19 cases at the time of publication.

"The virus is fragile; these mutations haven't changed that.
