Pasadena Star News The Pasadena Public Health Department on Wednesday, April 29, urged residents to take precautions against mpox and consider vaccination as cases increase in California.
Health officials said vaccination remains the best protection against severe illness, particularly for individuals at higher risk of exposure.
Mpox, a viral disease, is currently circulating in two strains, known as clade I and clade II. Clade I cases are typically linked to international travel, while clade II has been spreading at low levels in California since 2022, primarily through close physical contact.
A recent clade I case was confirmed in San Francisco involving an unvaccinated individual with travel-related exposure, while statewide data show a rise in clade II infections, officials said.
