Bolivia is battling a growing outbreak of chikungunya fever, with health authorities reporting three deaths and nearly 3,000 confirmed cases as of Wednesday, February 18, 2026. The eastern department of Santa Cruz is the epicenter of the outbreak, prompting a red alert issued on February 9th as the virus spreads rapidly. This outbreak underscores the ongoing global threat posed by mosquito-borne diseases and the importance of preventative measures.
The fatalities include two men, aged 83 and 56, and one woman, aged 78, all residents of Santa Cruz, according to Carlos Hurtado, head of Epidemiology at the Santa Cruz Departmental Health Service. Hurtado warned that the epidemic curve has not yet reached its peak, urging continued vigilance among the population. Currently, 32 patients are hospitalized, with seven listed in serious condition. The situation highlights the vulnerability of older adults to severe complications from chikungunya.
Chikungunya Cases Surge in Santa Cruz
The majority – 55 percent – of the 2,913 confirmed cases are concentrated in Santa Cruz de la Sierra, the department’s capital city. The positivity rate, indicating the proportion of tests returning positive results, currently stands at 65 percent, the highest recorded since the outbreak began. This high positivity rate suggests widespread transmission and a significant burden on the local healthcare system. The red alert triggered intensified mosquito control efforts, including fumigation and increased surveillance, across 27 affected municipalities within the department.
Chikungunya fever is a viral disease transmitted to humans through the bite of infected mosquitoes, primarily Aedes aegypti and Aedes albopictus. Symptoms typically appear three to seven days after a bite and include sudden high fever, severe joint and muscle pain, headache, and fatigue. While most people recover within a week, some individuals experience debilitating joint pain for months or even years. The Centers for Disease Control and Prevention (CDC) has issued a level 2 travel warning for Bolivia due to the outbreak.
Understanding the Threat and Prevention
While death from chikungunya is rare, the severe joint pain can significantly impact quality of life. The CDC recommends travelers to affected areas take precautions to prevent mosquito bites, including using insect repellent, wearing long-sleeved shirts and pants, and staying in accommodations with air conditioning or screens on windows, and doors. Fox News reports that a similar travel advisory was recently issued for the Seychelles, a group of islands in the Indian Ocean, as well experiencing a chikungunya outbreak.
The outbreak in Bolivia comes as public health officials worldwide remain vigilant against mosquito-borne diseases. Newsweek recently highlighted the growing concern over these viruses, particularly as travel increases.
Health authorities in Bolivia are continuing to monitor the situation closely and implement control measures to limit the spread of the virus. The focus remains on reducing mosquito populations and providing care for those infected. The public is urged to report any suspected cases to local health officials and to take proactive steps to protect themselves from mosquito bites.
The next official update from the Santa Cruz Departmental Health Service is expected on February 25th, where officials will provide further details on the progression of the outbreak and the effectiveness of the implemented control measures. Staying informed and taking preventative action are crucial in mitigating the impact of this ongoing health challenge.
