Amid record-breaking dengue cases globally, US health officials have issued a warning to doctors to stay vigilant for the mosquito-borne virus. Although there is no current outbreak in the US, the number of cases has tripled compared to last year, mainly from travelers returning from abroad. The Centers for Disease Control and Prevention (CDC) highlight the risk in tropical and sub-tropical regions, affecting nearly half the world’s population. Recent spikes led to the World Health Organization declaring an emergency, and Puerto Rico labeling it an epidemic. Doctors are advised to be aware of symptoms, patient travel history, and to consider dengue testing. |
What is dengue fever, and how is it transmitted?
Dengue fever, often called “break-bone fever” due to its painful symptoms, is transmitted through the bite of an infected mosquito.
Why have US health officials issued a warning about dengue?
The warning follows a significant increase in dengue cases globally and in the US, particularly among travelers returning from affected regions.
What regions in the US are at risk for dengue transmission?
The Gulf Coast, Florida, Texas, and parts of southern California are at risk due to favorable climates for mosquitoes.
What are the symptoms of dengue fever?
Symptoms include fever, nausea, vomiting, rash, aches, and pains, with severe cases leading to shock, internal bleeding, and death.
How can travelers protect themselves from dengue?
Travelers should stay in air-conditioned or screened areas, use insect repellents with DEET or picaridin, and avoid places with standing water and high mosquito concentrations.
