"Omicron", colds and flu – how to distinguish them by symptoms

In cold weather, a runny nose or cough is not uncommon. However, against the backdrop of the rapid spread of coronavirus, the first thought when symptoms appear is what if it’s an omicron. Are there any characteristic signs that make it possible to determine the diagnosis?

British edition Express, referring to Dr.Amir Khan, tells how to determine the presence of omicron and not to confuse its manifestations with a cold or flu. Although, as the doctor himself admits, “it’s really difficult.”

Yet the Omicron variant has unique features. For example, according to the doctor, the number of reports from those infected with the new strain of “sore throat and muscle pain” is increasing. Symptoms are not among the three classic signs of previous covid variants – loss of smell, cough, and fever. At the same time, the doctor says:

“Only 50% of cases report initial symptoms.”

The doctor recommends that if symptoms similar to a cold appear – a runny nose or headache – to do a PCR test for coronavirus and wait for the results, self-isolating:

Treat it as if you are “guilty until proven innocent.”

The recommendation to assume that cold symptoms are the result of omicron infection followed the first analyzes of data from a study of confirmed infections in the British capital. The analysis found no clear differences in early symptoms between Delta and Omicron. The overwhelming majority of the symptoms reported in the study were colds:

runny nose; headache; fatigue; sneezing; sore throat.

Now, based on the latest medical research, let’s compare the possible symptoms to better understand whether they indicate the flu / cold or omicron:

high fever: there is with “Omicron”, as with the flu, rarely with a cold; fatigue: sometimes with “Omicron” and a cold, with the flu; cough: for Omicron and flu (usually dry), for colds (mild); sneezing: no with Omicron and flu, with a cold; pains: sometimes with “Omicron”, with colds and flu; runny or stuffy nose: rarely with Omicron, there is a cold, sometimes the flu; sore throat: sometimes with “Omicron” and flu, there is a cold; diarrhea: rarely with Omicron, not with colds, sometimes with flu (in children); headache: sometimes with “Omicron”, rarely with a cold, there is with the flu; shortness of breath: sometimes with “Omicron”, not with colds and flu. …
