The U.S. Centers for Disease Control and Prevention (CDC) have reported an increase in chikungunya cases in Nicaragua, with most cases concentrated in Managua.
Mosquitoes are the vector responsible for transmitting the virus, and preventive recommendations include the use of insect repellent, protective clothing, and staying in air-conditioned environments or places with mosquito screens. Vaccination is recommended for travelers to affected areas, and pregnant women are warned about the risks of traveling to these areas, especially close to delivery, due to the possibility of transmitting the virus to the newborn and the risk of severe disease.
Vaccination should be postponed until after delivery, except in situations where there is a high risk of infection, in which case a healthcare professional should be consulted. Medical attention should be sought if symptoms such as fever, joint pain, headache, muscle pain, or skin rash develop.
Nicaragua is experiencing an increase in chikungunya transmission during 2026. In the week ending July 25, 195 cases were diagnosed, compared with 101 two weeks earlier and 12 at the end of May. In 2025, 20 cases had been confirmed, after no cases were reported in 2024. Available sources do not yet provide a national cumulative total for 2026 or information on deaths.
