80% of Indonesian Citizens Infected with Delta Variant

Jakarta, CNBC Indonesia – The Delta variant of Covid-19 is a frightening specter around the world today. But at the same time, the transmission of this virus is even under control in Indonesia. What’s the reason?

According to UGM Epidemiologist, Citra Indriani, it is very likely or around 80 percent of the Indonesian population has been infected by the Delta variant so that the number of positive cases of Covid-19 has decreased drastically due to the natural formation of group immunity where the body has antibodies specific to certain virus strains.

“More than 50% of covid infections are asymptomatic, maybe 80% of our population has been infected with Delta (variant). However, if you have been infected so much, do you already have group immunity and there is no threat of a third wave? Most natural infections form antibodies that are specific to virus or viral strain that infects, not for other strains. So that the natural immunity that is formed at this time may not be relied on if we get a new strain, “said Citra, as quoted from UGM page, Monday (21/11/2021) .

Another factor is the acceleration of the government’s intensive vaccination program, which is expected to minimize the severity if re-infected. The current vaccination program has reached 208 million who have been vaccinated and 88 million of them have received the complete vaccine dose.

“I think vaccination has a big role to play in preventing severe forms of illness because even though they have been vaccinated, they still have the potential to be infected and become sick. Looking at some of the recorded data that were infected in the January wave, also then re-infected the delta in June-July, and the cases died had history of not getting vaccinated,” explained Citra.

“The hope is of course that the acceleration of vaccination, and regional combing for vaccination, especially the elderly can play a role in mitigating the severe form of SARS-CoV 2 infection. Even if wave 3 occurs, our health system will no longer face thousands of severe cases every day.”

Although the average number of new positive cases every day is less than 400 cases, the policy of restricting mobility with the implementation of PPKM level 3 before Christmas and New Years according to him is the right thing to do. However, according to him, the increase in the number of people’s mobility today is unavoidable.

“The increase in mobility is something that cannot be avoided. If we look at 1.5 years of the pandemic, the wave of increase always begins with an increase in mobility, during Christmas-New Year and after Eid,” he said.

According to him, restrictions on mobility through the implementation of PPKM level 3 ahead of Christmas and New Year are part of a form of control so that massive transmission does not occur.

“Even though we limit mobility, mobility still occurs, but not as massively as if no restrictions were imposed. Restrictions on crowds and mobility are in accordance with previous learning that our wave begins in the Christmas-New Year and Eid period, especially in neighboring countries currently experiencing a wave of delta variant AY.4.2,” he explained.

According to him, restrictions on mobility and the application of health protocols in community activities will continue to be carried out until the entire world population is completely safe from Covid-19 infection and vaccinations have reached targets in all countries.

“We will still face Covid-19 cases as long as the world vaccination rate has not reached the target. So what is needed now is to change our mindset and accept that we will live side by side with this mobility restriction, we must go up and down the PPKM level, and adapt to the situation.” This is because there is no certainty to answer until when,” he concluded.
