Clark County confirms first mpox Clade I case as Clade II infections rise
Southern Nevada’s first confirmed Clade I mpox case was reported Tuesday in a Clark County resident with no reported travel exposure. The health district has also recorded 11 Clade II cases since August and urges people at risk to consider vaccination.
The Southern Nevada Health District confirmed Clark County’s first case of mpox Clade I on Tuesday, Oct. 20, in a resident with no reported travel exposure.
The district has also counted 11 confirmed Clade II cases since August 2026, a recent increase. Since the county’s first reported mpox case in June 2022, 365 cases have been recorded.
Mpox spreads mainly through close, sustained physical contact, including intimate contact, and can also spread through contact with contaminated bedding, clothing or towels. Symptoms may include a rash, fever, chills, swollen lymph nodes, headache, muscle aches and fatigue; they typically begin within three weeks of exposure, and illness usually lasts two to four weeks.
District Health Officer Dr. Cassius Lockett said the cases show that mpox continues to circulate locally. The district recommends vaccination for people at risk and advises anyone who may have been exposed to seek guidance promptly. People who develop a new, unexplained rash or other possible symptoms should avoid close contact and call a health care provider before visiting.
The JYNNEOS vaccine is expected to protect against both Clade I and Clade II, according to the district. Mpox vaccination is available to eligible people ages 18 and older at district immunization clinics. The series consists of two doses given four weeks apart; appointments can be made through the Southern Nevada Health District’s website.
