Singapore’s Communicable Diseases Agency (CDA) conducted a large-scale tuberculosis (TB) screening exercise in the Bedok Central neighborhood after tracing 13 genetically similar TB cases across three everyday public venues — a community clubhouse, a popular hawker food center, and a sports betting outlet.
A total of 3,169 people were screened between May 2 and 8, 2026. The results, released by the CDA on May 13, revealed that 14.9% of those screened — or 473 individuals — tested positive on initial blood tests and require chest X-rays to determine whether they have active TB disease or latent TB infection (LTBI). Free screening and follow-up services were available through June 5, 2026.
The three venues at the center of the cluster are Heartbeat@Bedok, Block 216 Bedok Food Centre & Market, and Singapore Pools Bedok Betting Centre — all locations with high, repeated community footfall, particularly among older residents.
How Authorities Traced the Cluster
The CDA’s National TB Programme used whole genome sequencing (WGS) — a molecular fingerprinting technique that compares the genetic code of TB bacteria from different patients — to identify that 13 TB cases diagnosed between January 2023 and February 2026 were genetically similar, indicating a shared transmission chain rather than unrelated individual cases.
Epidemiological investigation revealed that while several affected individuals were not close contacts of each other in the traditional sense, they shared overlapping activity patterns at the three Bedok Central locations over an extended period.
Singapore’s Senior Minister of State Tan Kiat How addressed public concern by clarifying that the TB cases did not involve hawkers or food stall staff, and that it remains safe to eat at Bedok Food Centre. That clarification was important given the potential economic and reputational impact on local food vendors.
Of the 13 identified cases: seven have completed TB treatment, five are currently undergoing treatment, and one has died from causes unrelated to TB. All are confirmed to no longer be infectious.

What a 14.9% Blood Test Positivity Rate Actually Means
It is important to interpret the 14.9% positivity rate correctly. A positive blood test for TB — specifically the Interferon-Gamma Release Assay (IGRA) — does not mean a person has active TB disease. The test indicates whether someone has been exposed to TB bacteria at some point. The vast majority of those who test positive are expected to have latent TB infection (LTBI): they carry the bacteria but show no symptoms, are not contagious, and will not automatically develop active disease.
The CDA stated the 14.9% positivity rate was “within expectations” given the presence of the identified transmission clusters and the high proportion of elderly residents in the Bedok area — a demographic with naturally higher latent TB prevalence. According to prior CDA data, latent TB prevalence among Singapore residents aged 70–79 is approximately 29%, compared to around 2% in the 18–29 age group.
Only individuals with an abnormal chest X-ray following a positive blood test would be further evaluated for active TB disease. Those confirmed with active TB will begin treatment promptly.
Community Risk and the Accountability Question
The three-year span of the Bedok cluster — from January 2023 to February 2026 — raises a legitimate accountability question: how long was the transmission chain active before it was detected, and could earlier identification have prevented additional exposures?
TB surveillance in Singapore relies primarily on clinician notification when active cases are diagnosed. The integration of whole genome sequencing into the National TB Programme represents a meaningful improvement in Singapore’s ability to link cases across seemingly unconnected individuals. Without WGS, the 13 cases might have been recorded as independent events, and the shared community exposure at Bedok Central might never have been identified.
That said, the multi-year timeline before the cluster was fully characterized illustrates the inherent challenge of TB detection: the disease progresses slowly, symptoms are non-specific, and people can remain contagious for months before seeking medical care. Singapore’s response — including free screening, onsite X-ray facilities, and proactive CDA outreach — appears consistent with public health best practices once the cluster was identified.
What Residents and Frequent Visitors to Bedok Should Do
While the free screening period ended June 5, 2026, individuals who frequently visited Heartbeat@Bedok, Block 216 Bedok Food Centre, or Singapore Pools Bedok Betting Centre between 2023 and early 2026, and have not yet been screened, should still contact the CDA or visit the National Tuberculosis Screening Centre for an assessment.
Residents throughout Singapore should also be aware of TB’s key warning signs: a persistent cough lasting more than two weeks, unexplained fever, night sweats, or unintentional weight loss. TB cannot be spread through food, shared utensils, or brief casual contact. Transmission requires prolonged, close exposure — typically over days to weeks — to an individual with active, untreated pulmonary TB.
TB in Singapore is fully treatable and curable with a standard course of antibiotics. Treatment typically lasts six months and is available at polyclinics under direct observed therapy (DOT) or the newer video-observed therapy (VOT), both of which are supported by Singapore’s national TB control program.
Singapore’s TB Landscape: Progress, But Ongoing Endemic Burden
In 2025, Singapore recorded 1,019 new active TB cases — the lowest annual total in at least ten years, and a reduction from 1,156 cases in 2024. The incidence rate fell to 24.2 per 100,000 population from 27.6 the year before.
Despite this progress, TB remains endemic in Singapore, particularly among older age groups and certain migrant worker communities. The CDA announced in early 2026 that it would move toward a more individualized TB care model, tailoring treatment supervision to patient needs and adherence while maintaining public health standards.
Frequently Asked Questions
Should I be worried if I visited Bedok Food Centre between 2023 and 2026?
If you are a frequent visitor and have not been screened, contact the CDA. Brief or occasional visits carry a low risk — TB requires prolonged close contact over days or weeks with an actively infectious person to transmit.
What is the difference between latent TB and active TB?
Latent TB infection (LTBI) means you carry TB bacteria but have no symptoms and are not contagious. Active TB disease means the bacteria is actively multiplying and you may be sick and infectious. Most people who test positive in the Bedok screening are expected to have LTBI.
Are the food stalls at Block 216 Bedok Food Centre safe?
Yes. Singapore’s Senior Minister of State Tan Kiat How confirmed the TB cases did not involve hawkers or food stall staff, and that it is safe to eat at Bedok Food Centre.
How does TB spread?
TB is an airborne disease transmitted through tiny respiratory droplets when an infectious person coughs, sneezes, or speaks. It requires prolonged close contact — typically days to weeks — for transmission to occur. You cannot get TB from food, shared utensils, or brief contact.
Is TB treatment available in Singapore?
Yes. TB is fully treatable and curable. Treatment is available free at Singapore polyclinics through directly observed therapy (DOT) or video-observed therapy (VOT). Early detection is key.
