No evidence diphtheria has spread further

download (1)MO, 11/8/2017 – There is no evidence that the contagious bacterial disease which killed a Bangladeshi construction worker last Friday has spread further, the Ministry of Health (MOH) said in a statement yesterday. All of his 48 close contacts – including those who stayed at the same dormitory in Yishun Avenue 7 and worked at Teban Gardens – have been cleared of diphtheria after screening conducted by the ministry on Tuesday.

“The two close contacts who had developed sore throats since Aug 3 and were warded in Khoo Teck Puat Hospital have been discharged. The remaining 46 contacts remain well. All 48 contacts have been given preventive medication and a booster diphtheria vaccine,” said MOH.

The death of the 21-year-old worker was the first local case of the disease in 25 years. Diphtheria causes inflammation of the mucous membranes, and can even result in fatal heart and nerve damage. Treatment involves administering diphtheria antitoxin, as well as antibiotics.

The worker had developed a fever and neck swelling on July 30, and was later isolated and hospitalised at Khoo Teck Puat Hospital, but died five days later.

MOH said cases of diphtheria are rare in Singapore. It added that the threat of spread is low because of compulsory vaccination against diphtheria as part of the National Childhood Immunisation Programme. That vaccination against diphtheria is effective in reducing infection and the severity of the disease.

According to the 2010 National Health Survey, a high proportion (92 per cent) of adult Singapore residents (citizens and permanent residents) aged 18 to 79 also have some immunity to diphtheria.
