Discovery of New Mpox Strain
Scientists in England have discovered a new strain of Mpox. The new variety was found in a person who had recently traveled to Asia, according to the UK Health Security Agency (UKHSA). Officials said they have identified a "new recombinant MPOX virus" – meaning it contains genetic material from different strains of the virus.
Characteristics of the New Strain
The UKHSA said genome sequencing revealed that the MPOX genome contained elements of MPOX clades Ib and IIb. This discovery is significant as it indicates the virus is evolving. Dr. Katy Sinka, head of sexually transmitted infections at UKHSA, noted that it is normal for viruses to evolve and further analysis will help understand more about how Mpox changes.
Impact and Severity
Although Mpox infection is mild for many, it can be serious. Vaccination is proven to be an effective way to protect against serious illness. The NHS is offering the MPOX vaccine to people who are thought to be at higher risk of catching the virus, such as men who have sex with other men and who have multiple partners.
Concerns and Next Steps
The identification of the new recombinant strain raises concerns about whether this could alter the transmissibility or virulence of the virus. The UKHSA said it would “continue to assess the significance of the burden”. Experts in the field have expressed concerns that the continued global spread of the virus without a decisive response could lead to more severe consequences.
Symptoms and Transmission
Symptoms of Mpox include a rash with blisters, spots, or ulcers that can appear anywhere on the body, as well as fever, headache, back pain, and muscle pain. A rash usually appears one to five days after fever, headache, and other symptoms. The virus spreads between people through direct contact with rashes, skin lesions, or scabs caused by the virus, including during sexual contact, kissing, cuddling, or other skin-to-skin contact. Additionally, contact with body fluids or contaminated items like bed linen, towels, or clothing can also spread the virus. There is a possibility of spread through close and prolonged personal contact such as talking, breathing, coughing, or sneezing.
