While the remarkably transmissible Omicron variant of COVID-19 is ripping via the United States at record premiums, some homes have been afflicted inconsistently, with some folks testing good for COVID-19 although others in the exact same house do not.

Coronavirus vaccines and boosters are really helpful at protecting against serious health issues, hospitalization and loss of life from COVID-19, but breakthrough bacterial infections can occur, normally with milder indications. In accordance to the Facilities for Sickness Command and Avoidance, “Anyone with Omicron an infection can distribute the virus to other people, even if they are vaccinated or never have signs.” So at this stage, if a home has a COVID-optimistic person, need to the relaxation of the family count on to get it no matter of vaccination standing?

Not essentially, states Dr. Lucy McBride, a doctor in Washington, D.C., who is also a Yahoo News healthcare contributor. She describes that folks and the virus relate to one one more in various techniques dependent on several aspects.

Some responses have been edited for clarity.

Yahoo Information: Why do some people today who are in the same residence get COVID-19, and other individuals never? Can it be in contrast to the flu?

Dr. Lucy McBride: It can be handy at this moment of the pandemic to commence to believe about comparing the flu and coronavirus. Not that they are equivalent at all, but you could have a scenario of flu in the loved ones, in the residence, and some folks could get infected and many others might not. Likewise, you could have a COVID scenario in your family, and some people in the spouse and children might get COVID and some could not. And regardless of whether or not a one man or woman will get infected and/or ill soon after an exposure in the house hinges straight on the quantity of virus that is set out by the COVID-constructive individual, and the disorders in that room, and the immune program and vaccination position of the man or woman who is becoming uncovered.

You can have inhaled a smaller viral load from the contaminated man or woman you can have inhaled a large viral load. In other text, you may perhaps have inhaled a diverse amount of virus. You also have a exceptional response to the virus based on your underlying health problems, your immune program and the other components at engage in. For example, if in the property you are exposed in a big room where the home windows were open, that is likely to be most likely a distinctive degree of publicity than another person who is sleeping in the similar space as the COVID-good man or woman. You might, for illustration, have had three shots and you are a youthful, healthier particular person, and you may well not get as unwell as a end result. We know that vaccinated folks get ordinarily a lot less unwell than men and women who are unvaccinated or have underlying health and fitness disorders.

Story carries on

So don’t forget that it is really not automatic that somebody will get contaminated in the household. Nevertheless residence transmission is the most typical problem. And the rationale we see widespread transmission of a specially contagious variant [is] due to the fact within just the same house, people generally aren’t masked and they are in near quarters.

When is a individual most contagious with the Omicron variant?

We are seeing with Omicron — this highly transmissible, though a lot less intrinsically critical, variant of coronavirus — that folks are ready to transmit the virus to other folks from as quickly as a day immediately after they are contaminated to up to 10 times soon after they are infected. But the much more widespread window is involving 24 hrs prior to building indications and 5 days immediately after producing signs or symptoms. But, of training course, these ranges are variable depending on the man or woman.

What is the tests timeline if you have had a COVID-19 publicity?

I’m recommending to my clients [that] they adhere to the CDC guidelines and isolate for five times and mask for day 6 to 10 and training caution during that time. I’m also recommending to my clients that if they can pay for it and they can accessibility it, to choose a quick antigen test at day five in buy to go away isolation. If that swift antigen check is unfavorable on day 5, you might be pretty guaranteed you’re not contagious to other people. If it is positive, you would check once more on day six. And if you’re damaging on working day 6, then you can leave isolation. A detrimental antigen check tells you with rather very good self-assurance that you’re no longer carrying contagious amounts of virus in your nose.
