The Department of Disease Control (DDC) says mpox remains under control in Thailand, with infections occurring sporadically and no evidence of widespread community transmission to date, despite a rise in cases since mid-2026.
DDC director-general Dr Montien Kanasawat said on Monday that Clade Ib had replaced Clade IIb as the dominant strain detected in the country.
Most patients are men aged 18-49, with sexual contact, exposure to infected household members and attending parties with infected people identified as risk factors.
Deputy DDC director-general Niti Hetanurak said the virus spreads mainly through close physical or sexual contact, contaminated clothing and towels, and prolonged exposure to respiratory droplets.
People with suspected infections should isolate, avoid sexual contact and seek medical attention, according to health authorities.
Confirmed patients may isolate at home if approved by doctors, but must remain isolated until all lesions have healed.
