Cases of COVID-19 in a number of countries, including Indonesia, are now ‘gassing’ again. Called the cause is the Omicron BA.4 and BA.5 subvariants, both subvariants believed to be highly infectious compared to the original strain. Even the spokesman for the Indonesian Ministry of Health, Mohammad Syahril, said that 87 percent of the BA.5 subvariant had dominated COVID-19 cases.
“And for your information, 87 percent of BA.5 has dominated this COVID. So it has shifted to the BA.5 subvariant,” he said during a live broadcast on the Indonesian Ministry of Health Radio, Monday (4/7/2022).
The symptoms most reported in this wave of COVID-19 are not fever and cough, but headaches. This is reported from the COVID-19 ZOE study, an application in the UK used by volunteers who report health conditions and symptoms of COVID-19, as well as positive or negative COVID-19 test results in the time since infection.

The data provided was then analyzed by researchers at King’s College London who track infections across the UK. Then, researchers identify groups of residents and areas that have a high risk of being infected or transmitting the Corona virus.
The study revealed that more than two-thirds of COVID-19 patients experienced headaches before undergoing the test and got a positive COVID-19 result. Some patients develop headaches before experiencing difficulty breathing.
Omicron ‘Alumni’ Can Reinfection?
Furthermore, this study also reveals the potential for a person to be exposed to these two Omicron subvariants after having been infected with Omicron BA.1 and BA.2. Usually cases of reinfection does 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, Saturday (9/7/2022).
