Omicron And Delta: Delta Or Omicron? How to find out which variant the patient is infected with when symptoms appear


Omicron has created havoc in India right now. People do not recover from the fear of a variant, that a new variant of the coronavirus emerges and is more dangerous than expected. It is believed that the new strain of Corona, Omicron, can bring a third wave in the country. The ever-increasing number of Kovid-19 cases is a strong proof of this. If seen, both Delta and Omicron are worrying.

So far experts and doctors have found that the new covid variant causes mild symptoms, which was not the case with Delta. With many testing positive for SARs-COV-2, people are increasingly curious to know whether they are infected with Omicron Delta or Delta. People are unable to differentiate between the symptoms of these two, which is making them difficult to understand which variant they are infected with. Let us tell you that unlike the delta variant, the symptoms of Omicron are mild, but it is more contagious.

New variant more contagious but less dangerous

a Japanese scientist and Kyoto University Professor of Health and Environment Hiroshi NishiuraAccording to the study, the Omicron variant has 4.2 times higher transmission efficiency than the Delta. He said – ‘Omicron variants spread rapidly and can also dodge vaccine and naturally made immunity.’

medRxiv site In another French study published on the Internet, it has been found that the Omicron variant of Kovid is 105% more contagious than Delta. It is clear from the available data so far that the new variant is more infectious and has infected a large population in a very short time.

These symptoms are not seen in people with Omicron

of Bangalore Dr. SN Aravinda, Consultant Internal Medicine, Aster RV Hospital Comparing Omicron with Delta, has said that the effect of the Kovid-19 variant may differ from person to person. Some reports suggest that people with Omicron are less likely to have a loss of sense of smell. But this symptom has been observed with other variants. Delta symptoms can be severe. Lung problem in Omicron and lack of oxygen Such symptoms are not observed.

The symptoms of Omicron are different from the symptoms of COVID-19 or Delta


Omicron Variants Scientists have been closely monitoring the new strain since its introduction. Apart from the heavy mutation in the spike protein of the variant, doctors have noticed some changes in the symptoms of both. starting Symptoms of Omicron Mild symptoms were reported, but people infected with Omicron complained of sore throat and mild fever, which almost got better on their own.

Which variant is it, which test will know?

When it comes to COVID-19, both antigen and molecular tests help identify the presence of the SARs-CoV-2 virus in the body. Then even if you are infected with any variant. Although the result of PCR test takes some time to come, but an antigen test reveals the COVID status in a very short time. Currently Rapid Antigen Test (RAT) and RT-PCR Test It is used to see whether a person is corona positive or negative.

Dr. Arvind says To test whether this is Omicron’s case, a genetic sequencing is needed, which can take 4 to 5 days. With the help of genetic material given during the test, scientists can confirm that a person infected with Delta or Omicron Yes or No.

role of testing

After a PCR test, the tests look for three genes with different parts of the virus, which is the spike (S), nucleocapsid (N2) or outer shell (E). Dr. Ankita Baidya, Infectious Disease Consultant, Manipal Hospital It says that if the S gene comes out PCR positive, then its Chances of getting Omicron infection Low and the possibility of delta infection is high. The doctor also says that if the S gene is PCR negative, it does not necessarily indicate Omicron or any other variant of Kovid.

This testing kit can detect Omicron

ICMR has approved an RT-PCR test kit named ‘Omisure’ specially developed by Tata Medical and Diagnostics to detect Omicron variants. The cost of this kit is Rs.250. But keep in mind that this kit cannot be used to detect Omicron at home.
