California Health Officials Urge Mpox Vaccination Amid Detection of Severe Strain in San Francisco
California health officials are urging residents at high risk to get vaccinated against mpox following the detection of a potentially more severe strain, Clade I, in San Francisco. This strain was identified in an unvaccinated adult who had close contact with an international traveler. The case marks the seventh Clade I mpox case in California, with the individual requiring hospitalization. Clade I infections are considered more concerning than the more common Clade II due to their potential for causing severe illness and easier spread through close personal contact. Despite the rarity of Clade I cases, Clade II cases are reportedly on the rise in California. Health officials emphasize the importance of vaccination, particularly for those with weakened immune systems, to prevent severe illness.
