As Canadians are urged to obtain their COVID-19 and influenza vaccines, many surprise when the pandemic will finish.

Because the colder climate units in, COVID-19 circumstances are rising in hospitals across the nation. Nevertheless, as COVID-19 continues to splinter, a brand new variant is on the horizon that deserves acknowledgment: the BQ.1.1 variant.

An in depth take a look at the COVID-19 BQ.1.1 variant

Totally different COVID-19 variants have reigned supreme at varied factors through the pandemic. Within the early-to-mid summer time, the contagious BA.5 COVID-19 subvariant rolled over Canada and different elements of the world. Now, just some months after BA.5 subsided, epidemiologists in the UK are warning of the BQ1.1 subvariant as the following model to observe.

How is BQ.1.1 totally different from earlier variants?

Within the U.S., BQ.1.1 infections are doubling every week. To date, this charge of unfold is double the velocity of different main subvariants. For instance, the brand new BQ.1.1 spreads twice as quick as BA.2.75.2.

BQ.1.1 is a subvariant of the Omicron variant BA.5. The lately up to date booster photographs ought to assist shield towards the subvariant.

BQ.1.1 is very contagious

Some COVID-19 variants are extra contagious than others. Presently, the most contagious COVID-19 variant is the pressure named BA.5.

BQ.1.1 is spreading throughout North America together with different contagious Omicron variants. Presently, the subvariants BQ.1.1 and BQ.1 are liable for over 11 per cent of new infections within the U.S., whereas B.A.5 includes 70 per cent.

BQ.1.1 is immune to sure antibody therapies

Whereas the contagion ranges of latest subvariants give pause for concern, an much more worrisome facet is BQ.1.1’s resistance to our pure antibodies and sure antibody therapies. Specialists famous earlier within the yr that sure BA.5 subvariants might elude the antibodies folks have constructed up by way of earlier infections and vaccinations.

Experiences present that BQ.1.1 often is the first subvariant to utterly resist antibody therapies, like Evusheld and Bebtelovimab.

What’s our vaccine efficacy with BQ.1.1?

Vaccine efficacy refers to how efficient vaccines are at defending the vaccinated inhabitants. It’s nonetheless too early to definitively state vaccine efficacy towards BQ.1.1. Nevertheless, it’s incomes a status as some of the immune-evasive COVID-19 variants to come up.

With out enough antibodies and vaccine options, the battle towards COVID-19’s continuously mutating subvariants would flip grim. Fortunately, the latest “bivalent” messenger-RNA boosters are nonetheless proving efficient towards the virus.

What are the signs of BQ.1.1?

Presently, the signs to be careful for are the identical signs linked to different Omicron-related subvariants. Omicron subvariants can have a shorter incubation time and faster onset of signs than different COVID-19 variants. The worst symptom is feeling like your throat is on hearth.

The most typical signs related to BQ.1.1 and different Omicron subvariants embody:

  • Congestion

  • Coughing

  • Runny nostril

  • Fatigue

What to do when you contract BQ.1.1

If you happen to consider you could have contracted the brand new B.Q.1.1 subvariant or any number of COVID-19, take a speedy take a look at and isolate for 5 days. As we head into the colder months, seasonal allergy symptoms, influenza, and the widespread chilly can even grow to be extra widespread. Many of those share signs with subvariant BQ.1.1, and maintaining a COVID-19 house testing equipment available might help you differentiate between COVID-19 and different seasonal sickness.
