Kompas.com reports that the Indonesian Ministry of Health (Kemenkes RI) has recorded 23 cases of Hantavirus in Indonesia from 2024 to 2026.
The Head of the Ministry of Health’s Communication and Public Information Bureau, Aji Muhawarman, said that of the total 23 cases, three patients have died. The resulting case fatality rate (CFR) for Hantavirus is 13 percent.
Based on Ministry of Health data, of the 251 suspected cases examined, 23 were declared positive. Of these, 20 patients were declared cured, while three others died. The 23 cases confirmed in Indonesia between 2024 and 2025 were spread across 9 provinces.
A closer examination of the Hantavirus case progression in Indonesia reveals a significant increase in 2025, when 17 cases were confirmed. In 2024, one case was recorded; to date, in 2026, five cases have been discovered.
The Indonesian House of Representatives is calling on the government to be more vigilant in detecting new cases of Hantavirus across all regions of Indonesia. Although the total number of Hantavirus cases is not large, the 13 percent fatality rate is a genuine concern.
Hantavirus is a zoonotic disease closely linked to environmental sanitation and exposure to infected rodents.
Densely populated environmental conditions, poor waste management, and suboptimal sanitation can increase the risk of disease spread.
Indonesian legislators are calling for heightened supervision at airports and seaports to prevent the spread of Hantavirus. The government is also asked to prepare standard operating procedures (SOPs) for handling Hantavirus at all Indonesian health facilities.
Indonesia’s Minister of Health. Budi Gunadi Sadikin is coordinating with the World Health Organization (WHO) after learning about the spread of Hantavirus on a cruise ship sailing in Argentina. The Ministry of Health is seeking guidance from the WHO on the handling and early detection of the virus.
Acknowledging that Hantavirus poses a serious public health threat, Indonesia is preparing for general screening, either by undertaking rapid testing as was done during the COVID-19 pandemic or by using PCR (polymerase chain reaction) reagents.
HANTAVIRUS IN BALI
While no case of Hantavirus has been confirmed in Bali as of 09 May 2026, the Bali Provincial Health Agency (Dinkes) is on the lookout for any suspected case of the disease appearing at any of the Island’s seaports or the Ngurah Rai International Airport.
Quoted by Balipost.com, the Head of Disease Prevention and Control of Bali, I Gusti Ayi Raka Susanti, confirmed that the Island is in an “alert” status despite having recorded no confirmed cases of the virus.
Susanti said health screening and surveillance are being conducted by public health workers at all ports and in every regency, including Denpasar. Diskes is coordinating controls at all ports in Bali with the Quarantine Officials of BBKK and KKP.
In discussing Hantavirus, Susanti said the disease is known to be spread by rodents, primarily via rat-contaminated urine, fecal droppings, and saliva. Symptoms of Hantavirus include fever, aching muscles, and respiratory difficulties.
The public is therefore reminded to pay attention to environmental hygiene and to avoid contact with rodents.
