• On February 13, 2023, Equatorial Guinea declared an outbreak of Marburg virus disease. Confirmed cases have been reported in multiple provinces (see map). Avoid non-essential travel to the provinces where the outbreak is occurring.
• The World Health Organization (WHO) is working with local health authorities to identify cases and conduct case investigations, strengthen surveillance, identify sources of transmission, and educate communities about the risks and dangers of Marburg.
• If you travel to Equatorial Guinea, you should:
  • Avoid contact with sick people who have symptoms such as fever, muscle pain, and rash.
  • Avoid contact with blood and other body fluids.
  • Avoid contact with dead bodies or items that have been in contact with dead bodies, participating in funeral or burial rituals, or attending a funeral or burial.
