Symptoms of infection with the Delta variant may differ slightly from those seen with earlier strains. The most common ones, however, are very “classic”. More importantly, we can draw conclusions from them that will allow us to recognize a possible Delta infection in the next wave, writes the Australian virologist.
- Doctors from India and European countries report many unprecedented symptoms of infection with the Delta variant
- However, in most cases, the symptoms are similar to those reported with the original COVID-19 variant as well as the Alpha strain
- Losing the sense of smell or taste is much less common now, while a runny nose has jumped to the high position in the «popularity» ranking

Delta variant – what are the most common symptoms?
Data on patients infected with the Coronavirus Delta variant show that the symptoms may differ slightly from those reported with the earlier variants. However, when analyzing the information collected by the British ZOE COVID-19 application, it can be seen that these deviations are not so significant, and the most common symptoms are quite classic – notes virologist Dr. Lara Herrero on the website «The Conversation».
- How to avoid the Delta variant? Seven important rules
Dr. Herrero writes that how a virus causes disease depends on two key elements. The first are viral factors, i.e. replication rate and pathogen transmission methods. They change as the virus evolves. The second are factors related to the body of the infected person and his immune system. These include age, gender, health, medications, lifestyle, physical activity and stress levels. Older people may have different symptoms than younger people, and data collected in a large hospital may differ from that collected from patients in a small surgery.
Data from the UK shows that the most commonly reported symptoms today may be different from those previously reported.
However, reports do not say what variant an infected patient is, and since the Delta variant is now dominant in this country, it can be assumed that these symptoms largely apply to this strain.
The five most common symptoms of COVID-19 today
The most common symptoms (also for the Delta variant) reported via the ZOE COVID-19 app in the UK Britain until June 23:
- Headache
- Sore throat
- Qatar
- Fever
- A persistent cough
Fever and cough are symptoms that have been reported very frequently since the beginning of the pandemic, and they affected most variants of COVID-19. A sore throat and headache are also somewhat “traditional” signals, while a runny nose was much less frequent in earlier reports. Loss of smell, once a very common symptom, is now in ninth place.
- WHO warns: COVID-19 cases are on the rise in Europe
Symptoms change as the virus mutates and its factors evolve. However, it is not known why this is so. However, as Dr. Herrero points out, the current information on the most common symptoms of SARS-CoV-2 infection today shows that what we might take for typical symptoms of infection, runny nose and sore throat, may actually be symptoms of COVID-19 infection. Especially since infection with the Delta variant is possible even after vaccination. And many experts believe that in late summer and early fall, this strain will account for 90% of the disease. infections in Europe.
The virologist emphasizes that although the Delta variant is slightly more resistant to vaccines, more than 90% of all currently used preparations are. protect against a serious course of COVID-19 that requires hospital treatment.
Delta variant – what to do?
Dr. Lara Herrero recalls that Delta is more infectious than the original coronavirus strain, as well as all subsequent COVID-19 variants. At the same time, society has become accustomed to the reality of the pandemic and people may be less vigilant.
- Delta variant mutates. This is very disturbing
– The war with the coronavirus is not over yet – warns the virologist. So we have to react accordingly. – Get tested if you have any suspicious symptoms, even if you just sniffle. Get vaccinated as soon as possible and follow the doctor’s instructions Writes Herrero.
