Health officials have identified three cases of Clade I mpox in Southern California residents with no history of international travel, confirming local community spread. Clade I differs from the more common Clade II strain and can cause more severe illness, though the overall public risk remains low.
Those at higher risk include gay, bisexual, and other men who have sex with men; transgender and nonbinary people; and individuals with HIV or weakened immune systems. Symptoms include rash, fever, chills, swollen lymph nodes, and body aches.
Mpox spreads mainly through close or intimate contact, including sex, cuddling, or contact with contaminated items like bedding. Health officials encourage vaccination with the two-dose JYNNEOS vaccine and advise seeking medical care for any new or unexplained rash.
