Omicron variant: Coughing was reported in 89% of those infected with the strain – CDC

The NHS is preparing for a spate of COVID-19 infections after recent data revealed cases are rising faster than previous waves. Omicron’s rapid spread has been attributed in part to an unprecedented ability to infect again. However, its mutations result in a much milder disease, with no reports of deaths with respect to the breed recorded so far. Now, the CDC recently released a report highlighting symptoms that prevail over others.

Efforts to understand the Omicron variant escalated after the World Health Organization in November classified it as a “variable of concern”.

The strain, known as B.1.1.529, harbors multiple mutations with the ability to spread rapidly and confer resistance to current immune defences.

In fact, the strain’s ability to infect those with immunity is attributed to more than 30 mutations seen in its spiky protein.

Fortunately, few hospitalizations have been reported in connection with the variant, and the symptoms are believed to be milder than those provoked by Delta.

In the Weekly Morbidity and Mortality Report, researchers at the CDC provided a preliminary profile of symptoms for the Omicron variant, drawing on the data available to date.

The report states that coughing is the most common symptom, affecting 89 percent of people with Omicron.

Anecdotal accounts by South African researchers described the cough as dry, often accompanied by an “itchy throat,” according to Reuters.

“Many of the first reported cases of omicron variant infection appear to be mild, although as with all variants there is a difference between infection and more severe outcomes,” the CDC report authors explained.

do not miss:

“Symptoms are expected to be milder in vaccinated people with previous SARS-CoV-2 infection than in unvaccinated people.

“The characteristics of the cases described in this report may also not be generalizable because the outcome of the case may be related to individual characteristics.”

The details of the report are based on 43 cases of infection attributed to the Omicron strains.

Only seven percent of people had “asymptomatic” or “unknown” infections, with 93 percent of cases considered asymptomatic.

“Even if most infections are mild, a highly transmissible variant could produce enough cases to confuse health systems,” the report’s authors wrote elsewhere.

The report lists coughing (89 percent), fatigue (65 percent) and congestion and a runny nose (59 percent) as the three most common symptoms.

Shortness of breath (16 percent), diarrhea (11 percent), and loss of taste or smell (eight percent) all appear at the bottom of the CDC’s list.

So far, there is no evidence that the Omicron variant can evade vaccine protection, but scientists have expressed concerns about heavy mutations in the variant, suggesting that it may warrant a reformulation of the vaccine.
