About Oropouche Fever

  • Oropouche fever is a viral disease caused by the Oropouche virus.
  • The virus is transmitted primarily through the bites of infected midges, specifically the Culicoides paraensis, and mosquitos.
  • The World Health Organization (WHO) reported the first-ever outbreak in Cuba on June 11, 2024.

Symptoms:

  • Symptoms are similar to those of dengue fever and typically begin between four to eight days after the bite.
  • Common symptoms include:
    • Sudden onset of fever
    • Headaches
    • Body aches
    • Chills
    • Joint stiffness
    • Nausea and vomiting (occasionally)
  • Most patients recover within seven days, and severe cases are rare.
  • There is no evidence of human-to-human transmission.

Treatment and Prevention

  • There is no specific vaccine or antiviral treatment for Oropouche fever.
  • Treatment is usually symptomatic, focusing on relieving fever and pain.
  • Preventative measures include avoiding bites from midges and mosquitos by using repellents, wearing protective clothing, and using insect nets.
