Thailand recovers first mpox clade Ib patient, no further cases

Thailand has successfully managed its first confirmed case of the mpox (formerly monkeypox) clade Ib variant, with the patient fully recovered, public health officials announced yesterday.

The 66 year old European male arrived in Bangkok on August 14 after travelling from Africa. The following day, he was admitted to a hospital, where laboratory tests confirmed the presence of the clade Ib variant of the mpox virus.

Dr Thongchai Keeratihatthayakorn, Director-General of the Department of Disease Control (DDC), confirmed that the patient’s lesions have completely dried, allowing for his discharge from the hospital and safe return home.

Testing was conducted on 43 individuals in close contact with the patient, and no additional infections were found.

“The first case of mpox clade Ib is now resolved, with no further transmission to others. However, we continue to closely monitor new cases, especially those from areas where the World Health Organisation has declared outbreaks.”

During a briefing, the Department of Medical Science highlighted the effectiveness of laboratory testing for the mpox virus, particularly for the highly severe clade Ib strain.

The initial detection of the clade Ib variant was achieved through lab testing using real-time PCR, with genetic analysis confirming it was indeed the clade Ib strain. This was further validated through whole genome sequencing.

To stay ahead of potential outbreaks, the department has collaborated with relevant units to continuously monitor mpox mutations and their impacts. Efforts include developing diagnostic guidelines tailored to the types and severity of virus strains detected, enhancing diagnostic standards, and strengthening coordination with other agencies to effectively control the virus’s spread.

Monitoring and preventive measures remain a priority as Thailand works to prevent any future transmission of the mpox virus, reported Bangkok Post.
