2 cases of mpox confirmed in S'pore, risk to general public is low: CDA

The Communicable Diseases Agency (CDA) confirmed two cases of mpox clade lb infection in Singapore.

According to a press release on Apr. 2, CDA said the two cases are "likely infected through sexual acitivies".

"As mpox is predominantly transmitted through intimate or prolonged physical contact, including sexual contact, the risk to the general public is currently low," CDA stated.

Cases

The first case is a 30-year-old male with no recent travel history, but reported having sexual contact recently.

CDA said that the individual developed symptoms on Mar. 25 and was admitted to the hospital on Mar. 30.

The laboratory testing confirmed on Mar. 31 that he was infected with mpox clade lb.

The individual's condition is stable and has since been discharged. He has been placed on home isolation until Apr. 20, pending further clinical review.

The second case is a 34-year-old male who reported recent travel history and sexual contact.

He had recently had prolonged physical contact with the first individual.

The second individual developed symptoms on Mar. 26 2026, and sought medical care on Mar. 31.

Laboratory testing confirmed infection with mpox clade lb on Apr. 1.

The individual's condition is stable and has been placed on home isolation until Apr. 21, pending further clinical review.

Investigations and contact tracing are ongoing for both cases.

Close contacts advised to monitor their health

Their close contacts have also been advised to monitor their health and seek medical care if they are unwell.

CDA explained that mpox is predominantly transmitted through intimate or prolonged physical contact, including sexual contact.

As such, population-wide vaccination is not recommended.

For groups at high risk, the mpox vaccine is available on a self-paid basis at the selected clinics and at the National Centre for Infectious Diseases from May 2026 onwards.

"The public should remain vigilant and protect themselves from mpox by avoiding high-risk sexual activities, such as engaging in casual sex or having multiple sexual partners.

In addition, travellers to countries affected by mpox should practise good hand hygiene, reduce physical contact with persons who are unwell and avoid consumption of bushmeat."
