Since 1960, Singapore has managed to reduce cases by 87 per cent. But mutant strains of TB germs resistant to drugs are a worry. APRIL CHONG reports
Tuberculosis (TB) was a big problem in post-war Singapore. The disease’s transmission was high and few effective testing and treatment options were available.
In the 1950s and 1960s, there were easily more than 5,000 new cases here every year, with 307 per 100,000 people coming down with the disease in 1960.
The Singapore Anti-Tuberculosis Association (Sata) was set up in 1947 by philanthropists.
In the years that followed, Sata’s vans went to various kampungs to take chest X-rays.
Dr K. Thomas Abraham, the chief executive officer of the association’s successor body, Sata CommHealth, said: “In those days, throw a stone and you’d hit someone with TB.”
In the 1970s and 1980s, treatment became more effective as TB-zapping drugs and various types of regimen were better developed. By then, health-care facilities were also shaping up.
TB treatment is now readily available, with more than half of the patients being seen at the TB Control Unit at Tan Tock Seng Hospital. Serious defaulters – those who fail to follow the daily treatment regimen
at polyclinics or the TB Control Unit – have to stay at the Communicable Disease Centre located near the hospital.
With TB figures having gone down since the 1950s and 1960s, Sata went into promoting community health, including smoking cessation, health education and health screenings. It was rebranded as Sata CommHealth last year to reflect its widened range of services.
However, its focus is still on lung health, said Dr Abraham.
In Singapore, TB figures have dwindled compared to population size – from 307 cases per 100,000 people in 1960 to 40 cases per 100,000 people in 2008. This works out to a reduction of about 87 per cent.
However, there were 1,451 new cases in 2008, the first increase in a decade. Doctors say it is too early to tell if the blip in the 2008 figure indicates a TB comeback here.
Worldwide too, awareness of the disease has increased and incidence rates have been falling slowly.
However, it is the threat of multi-drug resistant TB that now looms as current conventional drugs become increasingly unable to handle mutant strains of TB germs.
The drugs in use today were developed in the 1970s, so more research is urgently needed to find medicine that can handle the evolving disease, said Associate Professor Sonny Wang, the director of the TB Control Unit at Tan Tock Seng Hospital.
