Meanwhile, loss of smell, which was originally a common symptom, is now ranked ninth.
And the media has reported, according to UK health data, that there are several reasons why we are seeing symptoms develop this way. Perhaps the reason is that the data came mainly from patients who arrive at the hospital and are likely to be sicker. “
“Due to higher vaccination rates in older groups, young people now represent a greater proportion of Covid cases, and they show milder symptoms,” she added.
The source attributed the reason for the change in symptoms to the evolution of the virus and the different characteristics (viral factors) of the Delta strain.
“This data is important because it shows us that what we might think is just a runny nose and a sore throat, could be a case of COVID-19,” he added.
But he noted that “host factors” such as age, sex, other diseases, drugs, etc. were not taken into account, as in a rigorous clinical trial.
Likewise with all the self-reported data, some of these symptoms may not be definitive.
Although new viral strains may reduce the effectiveness of vaccines, two doses of the Pfizer and AstraZeneca vaccines still provide good protection against the symptoms of COVID-19.
