Tuberculosis is a common disease in Khlong Toei, where about 100,000 people live in poor living conditions, squeezed in an area of around a square mile. Active case finding is vital to prevent TB from spreading amongst the most vulnerable in this area. That is why BE Health trained eight Community Health Volunteers living in Khlong Toei’s quarter 70 Rai to identify people with suspected active TB. Since September, they have been relentlessly crisscrossing the narrow alleys of their neighbourhoods and going door to door in search of suspected active TB cases. Each outing, they identify eight to ten suspected cases, who are sent to Healthcare Center 41 to undergo diagnostic tests. It will take them until the end of the year to cover every household in 70 Rai before screening the next quarter.
