Background
Mpox (formerly known as monkeypox)[3] is an infectious viral disease that can occur in humans and some other animals.[4] Symptoms include a rash that forms blisters and then crusts over, fever, and swollen lymph nodes.[4] The illness is usually mild and most of those infected will recover within a few weeks without treatment.[5] The time from exposure to onset of symptoms ranges from five to twenty-one days and symptoms typically last from two to four weeks.[6] Cases may be severe, especially in children, pregnant women or people with suppressed immune systems.[7]
The disease is caused by the monkeypox virus,[lower-alpha 1] a zoonotic virus in the genus Orthopoxvirus. The variola virus, the causative agent of the disease smallpox, is also in this genus.[4] Human-to-human transmission can occur through direct contact with infected skin or body fluids, including sexual contact.[4] People remain infectious from the onset of symptoms until all the lesions have scabbed and healed.[7] It may spread from infected animals by handling infected meat or via bites or scratches.[7] Diagnosis can be confirmed by PCR testing a lesion for the virus' DNA.[4]Arrival
The Ministry of Health (MOH) detailed that the patient is a 42-year-old British man who works as a flight attendant.[1] He was reportedly in Singapore between 15 and 17 June 2022 and again on 19 June as he flew in and out of Singapore.[1] He tested positive for mpox on 20 June.[1]
On 6 July, it was confirmed that a 45-year-old Malaysian man tested positive becoming the first locally unlinked infection in the country.[8]
Situation
As of 5 August 2022, there are 10 locally transmitted cases and 5 imported cases in the country, all of whom are in stable conditions or ready to be discharged.[9]
Notes
- The World Health Organization (the authority on disease names) announced the new name "mpox" in November 2022. But virus naming is the responsibility of the International Committee on the Taxonomy of Viruses (ICTV), which is currently reviewing all orthopoxvirus species. As of March 2023, the official name of the virus remains "monkeypox virus".[3]
