Acute Respiratory Infections (ARI) caused by the Influenza A H3N2 Subclade K virus, commonly known as Superflu, have shown increased transmission activity globally since August 2025.
"Jakarta residents should remain alert to the potential spread of ARI,"
The illness is referred to as “Superflu” due to its relatively faster spread compared to other seasonal influenza strains.
Despite the rise in transmission, the latest epidemiological data released by the World Health Organization (WHO) does not indicate an increase in disease severity. Still, increased awareness is needed, particularly across Jakarta.
Jakarta Govt Urged to Bolster Preemptive Measures Against Superflu"Jakarta residents should remain alert to the potential spread of ARI and are advised to maintain their health, especially considering the high population mobility following the Christmas and New Year holidays, as well as the start of the rainy season," said Sri Puji Wahyuni, Head of Disease Prevention and Control at the Jakarta Health Agency, on Tuesday (1/6).
Based on Whole Genome Sequencing (WGS) results from influenza patient samples across Indonesia, released by the Ministry of Health on January 1, 2026, Superflu has been circulating in the country since August 2025.
The virus has so far been detected in eight provinces: East Java, South Kalimantan, West Java, South Sumatra, North Sumatra, Central Java, North Sulawesi, and Yogyakarta.
"As of now, no Superflu cases have been detected in Jakarta," she added.
Sri noted that based on end-of-2025 data, total ARI and pneumonia cases in Jakarta have continued to decline since the peak in October 2025.
In October, there were 309,532 cases reported, which dropped to 216,312 cases in December. Meanwhile, Influenza A cases also fell from 80 in October to just 3 in December.
She explained that the Jakarta Provincial Government continues to carry out sentinel surveillance for Influenza-Like Illness (ILI) and Severe Acute Respiratory Infection (SARI) at five health centers (Puskesmas) in each municipality and at one hospital, as an early detection measure for potential respiratory infection outbreaks in Jakarta.
"In addition, all healthcare facilities in Jakarta have been informed about the need for vigilance regarding the spread of Superflu, including recognizing its symptoms and signs, and strengthening both preventive and promotive measures, especially for respiratory infections and pneumonia," she shared.
Preventive measures being promoted to the public include frequent handwashing with soap, wearing a mask when ill, practicing proper cough etiquette, avoiding touching the face, maintaining a balanced diet, drinking at least two liters of water per day, getting adequate rest, and exercising regularly.
Jakarta Health Agency also reminds the public to be alert to signs of pneumonia or severe pneumonia, such as rapid breathing, chest wall indrawing, and oxygen saturation below 92 percent.
"The public is also advised to visit a healthcare facility immediately if symptoms persist," she asserted.
