Have you been infected with omicron or do you think so? Here you can find out everything you need to know about the corona variant, including symptoms and the incubation period.

Hanover – Many people are currently infected with Corona. Or more precisely, with omicron. According to the Robert Koch Institute (RKI), the omicron variant is currently the predominant variant in Germany at 99 percent. The proportion of sub-line BA.2 is currently almost 90 percent.

But how do the omicron sublineages differ from each other? What symptoms indicate a corona infection with the corona variant? How long is the incubation period? How long are you contagious? What medications relieve the symptoms? And when can you test yourself free? In this article you will find answers to all important questions.

Omicron: Symptoms, incubation period, course – everything about the corona variant

There are now five different sublines of the corona variant from Omikron, all of which are similar in terms of incubation period, symptoms and course:

Corona: How do different omicron variants differ from each other?

Study data published as a preprint by researchers from Japan indicate that the sub-form BA.2, which is prevalent in Germany, has a significantly higher transmissibility than BA.1, which dominated the infection process at the end of 2021. People infected with BA.2 infect around 40 percent more people.

The Robert Koch Institute (RKI) announced in February 2022 that there was no difference in the severity of the disease with omicron for those who had been vaccinated and those who had recovered – regardless of whether it was a disease with the omicron variant BA.1 or BA.2 . Not much is known about the new Omikron XE subline, but the corona variant Omikron XE seems to have a higher risk of infection. Also about Omikron BA.4 and BA.5, which the World Health Organization (WHO) has now included in the list of “Variants of Concern”.

Infected with omicron: what are the typical symptoms of the corona variant?

According to the current state of research, the symptoms differ only slightly in the different omicron sublines Corona variant.

With all omicron variants, omicron symptoms often resemble those of a cold. Typical omicron symptoms are:

  • Sore throat
  • headache
  • body aches
  • Sniffles

A pale, gray or bluish discoloration of the skin, lips or nail beds can also be symptoms of a corona infection on Omikron – both with Omikron BA.1, Omikron BA.2 or Omikron XE. Omicron can also trigger heart problems. If you have breathing problems or heart palpitations, you should see a doctor.

Infected with omicron: how long do the symptoms of the corona variant last, how long do you feel ill?

According to a recent study, the time of omicron symptoms decreases by many days when boosted. British researchers from Kings College London used data from 63,000 people for the large-scale “Zoe Covid Symptom Study”. For the Corona study, the scientists evaluated data from participants who had entered their symptoms themselves in the Zoe Covid app. They also reported how long their symptoms lasted on omicron or delta. This is reported by

The surprising result: After the third vaccination, the duration of the illness with symptoms was reduced by almost 4 days for those infected. Instead of 8.3 days after the second vaccination, the infected people only had symptoms of the disease for 4.4 days after the booster as a result of the corona infection with the corona variant. This shows how much the booster brings.

Infected with omicron: how long is the incubation period for the corona variant?

The incubation period is the time between infection with the pathogen and actual onset of the disease. According to the Robert Koch Institute (RKI), the corona virus has an incubation period of five to six and a half days. In the case of variants, however, the time at which corona symptoms appear or the disease breaks out can differ. Various studies have shown that the incubation period is shorter for the omicron variant and thus also for the omicron sublines BA.2 or XE and BA.4. According to the current status, the incubation period at Omikron should be three days. Omicron is also reflected in children with symptoms. A new omicron symptom in particular is causing a stir among researchers.

Corona infection with omicron: how long are you contagious with the corona variant?

Important: The incubation period should not be equated with the time in which you are contagious after being infected with the corona variant. “It is considered certain that the contagiousness is greatest in the period shortly before and after the onset of symptoms and that a significant proportion of transmissions take place before the first clinical symptoms appear,” says the RKI website.

Infected with omicron: which drugs relieve the symptoms of the corona variant?

With omicron, many people have symptoms similar to those of a cold. Many infected people have a sore throat or cough. Lozenges or gargling solutions from the pharmacy can help here. Inhaling sage can also help with coughs and colds. If the nose is running, infected people can use decongestant nose drops. Painkillers such as paracetamol and ibuprofen help against headaches.

Omicron symptoms: How long do I have to be in quarantine after being infected with the corona variant?

Only contact persons have to be quarantined. Anyone infected with omicron must be isolated. And of course the question arises: When can I test myself for Omikron?

The answer: Every person with a confirmed corona infection must go into isolation for 10 days. This applies from the onset of symptoms. The prerequisite for the end of isolation is that you have not had any symptoms for at least 48 hours at this point.

You can reduce home isolation to seven days. Provided they can present a negative result of a rapid antigen test. This must be carried out and officially certified by a doctor or in a test center or pharmacy. In a special case, you can leave the corona quarantine earlier with Omikron and a positive PCR test.

In Bavaria there is an exception. Since April 13, people infected with corona have only had to be in isolation for five days after a positive test result if they have had no symptoms for at least 48 hours. Another test is not necessary. If symptoms still occur on day five, you have to be in isolation for longer. But no longer than 10 days. Quarantine in Bavaria is recommended for contact persons, but no longer ordered.

Corona in Lower Saxony and Germany: That is the situation

The nationwide seven-day incidence has continued to fall (as of April 18). According to the RKI, there were 808.8 new infections per 100,000 inhabitants (a week ago the value was 1080). The health authorities in Germany reported 20,482 new corona infections to the RKI within one day (a week ago: 30,789).

However, it can be assumed that fewer cases were reported because of the Easter holidays. Lower Saxony, Baden-Württemberg and Brandenburg have already stated that they did not provide complete figures. On April 15, Lower Saxony reported 1,327 new infections to the RKI (data from April 18, 2022). (Jennifer Koellen)
