A recent report examined cases of dengue fever in the United States that were linked to travel. It looked at data from 2010 through 2021. The main finding was that there were more travel-associated dengue cases in 2019 than in the years before and after it within that timeframe.
The report did not provide specific details on how many people were included, what countries they traveled to, or the exact size of the increase. It also did not report on any safety concerns or serious outcomes from these cases. This type of report is observational, meaning it tracks patterns but cannot prove what caused the rise in cases in that particular year.
Readers should understand that this information shows a pattern from past data. It does not predict future risk or give advice on travel. The report highlights that dengue, a mosquito-borne illness, can be brought back by travelers. People planning international travel can talk to their doctor or a travel clinic for current, personalized health recommendations.
