JAKARTA - The DKI Jakarta Health Office stated that until now no cases of super flu have been found in the capital city. However, vigilance is still needed considering the high mobility of residents after the Christmas and New Year holidays and the arrival of the rainy season.
The Head of the DKI Jakarta Health Office, Ani Ruspitawati, explained that the super flu is an Acute Respiratory Tract Infection (ISPA) disease caused by the Influenza Type A H3N2 Subclade K virus. This disease is called super flu because of its relatively faster spread rate.
"This virus has started to increase its transmission activity since August 2025 worldwide. However, the latest epidemiological data released by WHO does not indicate an increase in the severity of the disease," Ani told reporters, Monday, January 5.
Based on the results of whole genome sequencing (WGS) released by the Ministry of Health on January 1, 2026, SuperFlu is known to have circulated in Indonesia since August 2025.
Currently, SuperFlu has been detected in eight provinces, namely East Java, South Kalimantan, West Java, South Sumatra, North Sumatra, Central Java, North Sulawesi, and the Special Region of Yogyakarta.
"Based on this information, there is currently no case of super flu in the DKI Jakarta Province," said Ani.
Although there have been no cases, the potential for transmission is still considered to exist. The Health Office reminds the public not to be complacent about the risk of ISPA.
"Jakarta residents must always be alert to the potential for transmission of ISPA disease, considering the quite high population mobility after the Christmas and New Year holidays and the start of the rainy season," said Ani.
For anticipation steps, the DKI Jakarta Provincial Government is said to continue to carry out early monitoring through a surveillance system at health facilities in 5 health centers in each city and 1 hospital to detect early indications of the spread of ISPA cases in DKI Jakarta.
In addition, all health facilities in Jakarta have been informed about vigilance against the super flu, including the identification of symptoms and strengthening of promotional and preventive measures.
The public is advised to wash their hands often with soap, wear a mask if they are sick, apply cough etiquette, avoid touching their faces, consume a balanced nutritional intake, get enough rest, exercise regularly, and immediately go to a health facility if they experience continued complaints.
"Be aware of the signs of pneumonia and severe pneumonia such as rapid breathing, pulling the chest wall inward, oxygen saturation less than 92 percent PP," said Ani.
The Ministry of Health of the Republic of Indonesia previously confirmed the detection of dozens of cases of influenza A (H3N2) subclade K in the country. However, the government ensures that the spread of the virus is still within the limits that can be controlled and does not cause a higher level of severity than other types of influenza that have been circulating.
The Director of Communicable Diseases at the Ministry of Health, Prima Yosephine, revealed that the trend of increasing influenza A (H3) globally began to be seen in the United States since the 40th week of 2025, coinciding with the start of winter. Meanwhile, the subclade K was first recognized by the Centers for Disease Control and Prevention (CDC) in the United States in August 2025 and has now been recorded to spread to more than 80 countries in the world.
"Based on the WHO assessment and available epidemiological data, influenza A(H3N2) subclade K does not show an increase in severity. The symptoms that appear are generally similar to seasonal flu, such as fever, cough, runny nose, headache, and sore throat," said dr. Prima, quoted from the official statement of the Ministry of Health on Thursday, January 1, 2026.
In the Asian region, the presence of subclade K has been reported in a number of countries such as China, South Korea, Japan, Singapore, and Thailand since mid-2025. Although the influenza A(H3) virus is the most commonly found variant, the number of cases in these countries actually shows a downward trend in the last two months.
Similar conditions also occur in Indonesia. National surveillance data notes that influenza A (H3) is still the most dominant variant, but the overall number of cases has decreased. As a protection effort, the public is urged to consistently implement clean and healthy living behaviors, maintain physical condition to stay in good condition, and consider annual influenza vaccination.
