Coronavirus infection can also occur after vaccination – delta is a distinct symptom

The main symptoms of the original coronavirus were fever, annoying cough and loss of taste rather than smell, and the delta variety is mainly associated with headache, sore throat, runny nose and fever, he writes. news.com.au.

Researchers in the UK have analyzed the delta strain and found that its symptoms have not changed much since the initial outbreak, and that the delta strain coronavirus reminds young people of a ‘simple cold’.

The Zoe Covid Symptom Study, based on patients’ own testimonials, found that olfactory strain was less likely to cause olfactory loss and shortness of breath.

Changes in symptoms have been linked to an increase in the number of delta infections, which currently account for 90% in the UK. cases.

Tim Spector, who led the study, says that more and more people are at risk of mixing the coronavirus with a simple cold as symptoms change.

“Since the beginning of May, we have been analyzing the main symptoms mentioned by the users of the application, and they are no longer the case. The delta option seems to work a little differently. People may think they are caught up in a simple seasonal cold, so they continue to walk around at parties where one patient can infect up to six people. We think this will cause us a lot of problems, “says T. Spectoras.

Urge young people not to shake hands about cold symptoms and stay home to get tested.

Lara Herrero, an infectious disease expert at Griffith University, writes in The Conversation that the causes of changes in symptoms are determined by several factors.

“There are even a few reasons why symptoms change the way they do. This may be because the data first came to us from patients who were treated in the hospital, meaning they were sicker. Since a significant proportion of the older generation are vaccinated, most cases are now younger patients and experience milder symptoms. This may be due both to the evolution of the virus and to the distinctive characteristics of the delta strain. We still cannot answer this question of why exactly the symptoms are changing, ”says L. Herrero.

Researchers in the UK have also found that the symptoms of the virus experienced by patients and those who have not received the vaccine are also different.

“Basically, the COVID-19 symptoms reported by people on the app don’t differ too much regardless of whether people are vaccinated or not. However, those who were vaccinated experienced fewer symptoms, got sick more easily, and got up faster. ”Say the experts.

The main symptoms identified in the vaccinated and the patients were runny nose, headache, sneezing and sore throat. Interestingly, sneezing is more commonly reported as a symptom by those vaccinated against the coronavirus.

The symptoms that patients experience after a single dose of the vaccine are even different, with the most common being headaches, runny nose, sore throat, sneezing, and coughing.

“For those who have received a single dose of the vaccine, one of the five most common symptoms is a bothersome cough, but it still reduces sneezing and a runny nose. In the past, the two symptoms were not associated with the coronavirus, “experts said.

Herrero says that while new strains of the virus can reduce the effectiveness of vaccines. Currently, the AstraZeneca and Pfizer vaccines provide good protection against the virus.

“Importantly, both vaccines account for more than 90 percent protection against a serious form of the disease that should be treated in a hospital. In some cases, it is possible to become infected after vaccines, but still the course of the disease will be easier ”, says L. Herrero.

The delta variety, which was first found in India, now accounts for 90 percent. in all cases detected in the United Kingdom.

“It seems that the principle of operation of this variety is a little different. People think they have suffered from some kind of seasonal cold, so they keep going to parties. Such a patient can infect at least six more. I think this makes it very difficult to solve the problem. The message we send is simple: If you are young, your symptoms are likely to be milder in any case. The feeling can be like a bad cold or just feeling weird. It’s important to stay home and get tested, ”advises Professor Tim Spector, who leads the Zoe COVID-19 Symptom Study.
