Semarang: Health officials in Semarang are urging residents to remain calm despite recent reports about a new strain of influenza A (H3N2), often referred to as the “super flu,” that has been detected in Indonesia. However, they are also emphasizing the importance of vigilance to prevent transmission.
Dr. Abdul Hakam, head of the Semarang City Health Office, explained that this “super flu” is essentially the same as influenza type A, but belongs to a K subclade. “This is influenza type A, but the K subclade variant appears to spread more quickly. However, it doesn’t seem to be associated with a high mortality rate or a significant increase in hospitalizations,” he said, according to Antara, on Wednesday, January 7, 2026.
Symptoms of the new strain are consistent with typical influenza, including cough and a runny nose. Treatment also remains the same, focusing on adequate rest and a nutritious diet to boost the body’s immune system.
“If a fever develops, over-the-counter medication can help. If symptoms persist, please visit a community health center, clinic, or hospital if further medical attention is needed,” he added.
As of now, no cases of the “super flu” have been identified in Semarang. Despite the increasing media coverage, officials are advising the public not to panic.
“This variant has been known since August of last year. To date, none of the samples we’ve sent to national laboratories have been identified as the K subclade,” Dr. Hakam stated.
Overall fitness plays a crucial role in susceptibility to viral infections. A weakened immune system makes individuals more vulnerable to viruses, including this new influenza strain.
“Therefore, when you start to feel a sore throat or develop flu-like symptoms, it’s important to stop activity, rest at home, and prioritize self-care. Eating nourishing foods and engaging in relaxing activities – like watching a show or practicing mindfulness – can help strengthen your immune system,” he explained.
Dr. Hakam also recommends that individuals experiencing flu symptoms rest, reduce activity levels, and wear a mask when interacting with others.

Indonesia’s Minister of Health, Budi Gunadi Sadikin, previously confirmed that influenza A (H3N2) subclade K, or the so-called “super flu,” has been circulating for some time, similar to common seasonal influenza. He emphasized that the virus is not as deadly as COVID-19 or tuberculosis (TB).
“There’s no need to worry that this is like COVID-19 in terms of its fatality rate. It’s just a regular flu – influenza H3N2,” he said.
Like other seasonal flu strains, this virus can reappear with each infection. Cases typically increase during the winter months in countries with four seasons, but the rise is generally less pronounced in countries like Indonesia.
“That’s why those countries offer annual influenza vaccinations,” Budi noted.
While not as dangerous as COVID-19, residents are still encouraged to prioritize their health and immunity through adequate rest and regular exercise. This information is particularly relevant as influenza viruses continue to evolve and circulate globally.
