Thailand is confronting a growing public health challenge as outbreaks of dengue, chikungunya, and Zika affect communities and the nation’s thriving tourism sector. New research shows these viruses, common in tropical climates, are becoming more entrenched, stressing healthcare systems and prompting urgent discussions on protecting residents and visitors during peak travel season. These findings from reputable infectious disease journals fuel the debate on how Thailand can safeguard people and sustain tourism.

Colombia has declared a nationwide health emergency after a sudden yellow fever outbreak. Officials report at least 34 deaths and 74 confirmed cases in 2025, signaling a sharp resurgence of a mosquito-borne illness in a region that had seen few cases in recent years. The response from the Colombian government underscores growing alarm and offers a cautionary lesson for Thailand, where Aedes-borne diseases are a constant concern.

Yellow fever is caused by a virus transmitted mainly by Aedes and Haemagogus mosquitoes. Early symptoms often resemble those of dengue or Zika, including fever, muscle pain, and headaches. In severe cases, the disease can cause jaundice, bleeding, and organ failure. Mortality can be high in the most serious phase, a reminder of why vaccination and vector control are critical. Health authorities have noted that vaccination is required for travelers to high-risk areas during Easter, as uptake becomes a focal point of the national campaign.

Colombia has declared a nationwide health emergency following a sudden and deadly outbreak of yellow fever, with at least 34 deaths and 74 confirmed cases reported so far in 2025, according to official Colombian health authorities (BBC; Reuters). The government’s urgent response underscores growing alarm about the re-emergence of this mosquito-borne virus in a region that had seen virtually no cases in recent years—a trend that should serve as a wake-up call for countries like Thailand, also home to mosquito-borne diseases.
