The Delta variant of the Corona virus is characterized by new symptoms.. the most important of which is a runny nose

It has now been more than 18 months since the world is in the grip of the deadly coronavirus that has infected millions of people around the world, and as the vaccination campaign is taking time, there is a new type of coronavirus that has become a major cause of concern among people.


Earlier this month, according to a report by the "Healtlsite" website, the World Health Organization announced the rapid spread of the delta variant that was also a possible cause of the second coronavirus wave in India. This strain, which was first identified in India, has now mutated to form another highly transmissible variant. Delta Plus.

At the beginning of the epidemic, some common symptoms such as fever, headache, and loss of smell were identified as warning symptoms of MERS infection, but with the development of the virus, the more common symptoms also seem to have changed.

New COVID-19 symptoms associated with the delta variant


As the coronavirus has mutated, experts have warned that the most common symptoms of COVID-19 may have changed from those traditionally associated with infection with the virus. While fever and cough have always been common symptoms of COVID-19, headaches and sore throats have traditionally appeared for some people, but they are rare. Runny nose has been reported in previous data, meanwhile anosmia, which was originally common, now ranks ninth.

There are several reasons why we see symptoms developing in this way, it may be that the data was mainly coming from patients who presented to the hospital who are likely to be sicker, and given the higher rates of vaccination coverage in the older age groups, young people represent Now a larger percentage of COVID cases, and they tend to have milder symptoms.


The reason why youngsters have milder symptoms of MERS infection may be the evolution of the virus, and the different characteristics (viral factors) of the delta variant, but the reason for the change in symptoms is still uncertain.


While we still have more to learn about the delta variant, this emerging data is important because it shows us that what we might think of as just a mild winter cold, runny nose and sore throat could be a case of COVID-19.

Does the COVID-19 vaccination affect symptoms?


Although new variants of Corona can harm the effectiveness of vaccines, Delta vaccines such as Pfizer and AstraZeneca still offer good protection against symptoms of COVID-19 after two doses, and according to reports, both vaccines have been shown to provide greater than 90% protection from Serious illness requiring hospital treatment.
