Indonesia's Two New Weapons Against TB

Jakarta (ANTARA) - Tuberculosis bacteria can survive for months in damp, poorly ventilated spaces with little exposure to sunlight. Several environmental health studies indicate that the bacteria causing TB actually weaken quickly when exposed to direct ultraviolet light for 15 to 30 minutes. However, in many cramped homes without windows and adequate air circulation, the opposite conditions prevail. Stuffy and dark rooms become ideal environments for the bacteria to survive and increase the risk of transmission. For years, TB management in Indonesia has focused primarily on treating patients. The homes where patients live have rarely been central to the strategy. Yet, many sufferers, after being declared cured, return to the same environment where they were first infected—stuffy, densely populated rooms with minimal sunlight. In this context, the government is beginning to implement a different approach. Data from the Indonesian Government Communication Agency (Bakom) records more than 241,000 TB cases detected up to early May 2026. This figure emerged after the government expanded active screening through the Free Health Check (CKG) programme, close contact tracing, and integrated reporting via the Tuberculosis Information System (SITB). Indonesia remains the second country with the highest TB cases globally after India, according to the Global Tuberculosis Report 2025. Behind this high detection rate, there are two concurrent policy changes underway. The first addresses the living conditions of TB patients. The second alters the treatment approach for drug-resistant TB, which has long been known to be lengthy and arduous. Through collaboration between the Ministry of Health and the Ministry of Housing and Settlement Areas (PKP), the government targets the renovation of 2,000 homes of TB patients throughout 2026, expanding to 10,000 units in 2027. This programme is directed at low-income groups categorised in Deciles 1 to 4 of the National Socio-Economic Single Data (DTSEN). The targeted homes are generally in densely populated areas with minimal ventilation and poor natural lighting. In many cases, one house accommodates several family members in cramped spaces without adequate windows. These conditions make infectious droplets more likely to persist in the air. Deputy Minister of Health Benjamin Paulus Octavianus stated that TB management will not be complete if treated patients return to homes that remain sources of transmission. Therefore, home renovations are viewed as part of disease control, not merely social housing assistance. The environmental health standards used are actually quite simple. Ideal home ventilation should be at least equivalent to 10 per cent of the floor area, natural lighting at least 60 lux, and occupancy density no more than two people per room sized over eight square metres. However, these standards are difficult to find in many dense urban areas such as North Jakarta, Bekasi, and Tangerang, which have long borne a high TB case load. This approach signals a change in the national TB management policy. A disease previously more often understood as a health service matter is now being treated as an environmental and housing quality issue.
