A number of countries, including Indonesia, are now hit by a surge in COVID-19 cases. This time, impact the Omicron BA.4 and BA.5 subvariants. So in this wave, what symptoms appear the most?
The ZOE COVID study app reported that headache was the most reported symptom. Remember, this application in the UK is used by volunteers who report health conditions and symptoms of COVID-19, as well as positive or negative COVID-19 test results within some time since being infected.
The data provided was then analyzed by researchers at King’s College London who track infections across the UK. Then, the researchers identified the groups of residents who were most at risk and the areas that had the highest risk of being affected by Corona virus infection.
The study found that more than two-thirds of COVID-19 patients experienced headaches before testing and tested positive for COVID-19. Some patients have a headache before experiencing difficulty breathing.
Reinfection Risk
Furthermore, this study reveals the potential for a person to be exposed to Omicron BA.4 and BA.5 subvariants after having been infected with Omicron BA.1 or BA.2. However, in general, cases of reinfection do not occur in less than three months after the first infection.
“There must have been a lot of people who got COVID earlier in the year who got it again, including some with BA4 or BA.5 who had previously been infected with BA.1 or BA.2 (within) just four months, who would have thought they would have been protected ,” said ZOE Health Study application leader Prof Tim Spector, quoted from Mirror News UK, Monday (4/7/2022).
