Everything you wanted to know about the symptoms, severity, and contagiousness of these two strains, but were too lazy to ask your doctor.
The delta strain of coronavirus no longer dominates the world. Now there is a new strain — Omicron. This strain is less likely to cause severe symptoms, but it spreads much faster, even among vaccinated people.
In a new article, we decided to collect all the facts about these two strains of coronavirus and compare them.
Symptoms of strains Omicron and Delta
Attention! No matter what we say about different strains, it is still a coronavirus. So some symptoms may be more pronounced, but they are still symptoms of the coronavirus.
Doctors say that people with coronavirus show a wide range of symptoms, both mild and severe. And although this is not an exhaustive list, there are symptoms that are common with coronavirus:
- fever and chills;
- shortness of breath, difficulty breathing;
- muscle and body pain;
- loss of taste, smell;
- sore throat;
- nausea, vomiting, diarrhea;
- stuffy nose, runny nose.
There is no official information about what symptoms are common with Omicron and Delta strains. But there is some general information:
- For example, studies say that Delta causes headache and runny nose more often, and fever, cough and loss of smell are rare.
- Micron However, according to research, it is very similar to the common cold. Its five main symptoms are headache, runny nose, fatigue, sneezing, and sore throat.
- Both Delta and Omicronalmost no fever, cough, loss of smell and taste.
Infectivity of Omicron and Delta strains
When Delta just emerged, scientists thought it was more than twice as contagious as other variants of the coronavirus. Unvaccinated people are still at risk, and they are not only more likely to get infected, but also to infect others. Fully vaccinated people can still get the Delta strain, but the symptoms will be poorer. The vaccine still protects against severe symptoms and death.
As for the strain Micron, to date, there is no complete data on its contagiousness. Preliminary studies show that the Omicron strain spreads faster than the Delta strain. Scientists have found that in the same place, Omicron spreads faster than Delta in vaccinated and revaccinated people. In unvaccinated people, the rates of contagiousness are the same. The preliminary conclusion is that such infectiousness of Omicron is due to its ability to avoid the effects of immunity.
As of the end of December 2021, the Omicron strain is replacing the Delta strain.
The severity of Omicron and Delta strains
Although Omicron is more contagious than Delta, its symptoms are much milder, according to research. About this also wrote on her twitter Rochelle Walensky, MD, director of the US Centers for Disease Control and Prevention.
“A new study on the severity of Omicron versus Delta. 53% less risk of symptomatic hospitalization. 74% lower risk of being admitted to an intensive care unit. 91% less risk of death.”
What does it all mean?
First, despite the fact that Omicron and Delta differ in symptoms, severity and contagiousness, it is still a coronavirus. The basic prevention measures are still the same: you need to get a vaccine, wear a mask, maintain social distance and stay away from others if you are sick.
Secondly, with regard to the Omicron strain, you need to get a vaccine and also get a booster dose of the vaccine if your family doctor allows it.
As new information becomes available, we will update the article. But you will be able to get new and up-to-date information faster from your doctor.
And, of course, do not panic. Despite the fact that the coronavirus is dangerous, do not wind yourself up!
