Jeonnam Gwangju Special City Issues 'Vacation Travel Infectious Disease' Advisory

Pre-Departure Vaccination Essential Amid Measles Outbreaks
Report Recent Travel to Healthcare Providers if Fever or Diarrhea Occurs After Return

With the arrival of the summer vacation season, overseas travel and outdoor activities are surging, requiring special attention to major infectious diseases.

According to Jeonnam Gwangju Integrated Special City on August 3, representative illnesses to watch out for during summer include measles, waterborne and foodborne infectious diseases, and mosquito-borne diseases. Measles, which is currently spreading worldwide, continues to produce cases not only in major international travel destinations such as the Philippines, Mongolia, and Japan, but also in countries like the United States and Mexico.

Measles is highly contagious and causes fever, cough, runny nose, conjunctivitis, and a widespread skin rash. In particular, people with weakened immune systems, such as infants and pregnant women, are at greater risk of developing serious complications like pneumonia or encephalitis.

To prevent measles, travelers should check that they have received both doses of the measles, mumps, and rubella (MMR) vaccine before departing. Anyone born after 1968 who has not been vaccinated must receive the vaccine at least four weeks prior to departure.

The hot and humid summer weather promotes the proliferation of bacteria and viruses, increasing the risk of waterborne and foodborne infectious diseases. These diseases, caused by consuming contaminated water or food, frequently occur at vacation spots or large-scale meal facilities. As they can cause diarrhea or vomiting that may lead to severe dehydration, strict precautions are necessary.

In Korea, following an increase in the population of Culex tritaeniorhynchus mosquitoes, which transmit Japanese encephalitis, a nationwide Japanese encephalitis alert was issued on June 17. In Vietnam, Thailand, the Philippines, Indonesia, and Malaysia, mosquito-borne diseases such as dengue fever, chikungunya fever, and Zika virus infections continue to pose risks.

These diseases commonly present symptoms such as fever, headache, muscle pain, and joint pain, with some causing rashes as well. Both in Korea and abroad, thorough personal hygiene—such as frequent handwashing and proper cough etiquette—should be observed during travel. If any suspected symptoms such as fever, rash, or diarrhea appear within two weeks after a trip, individuals should refrain from going outside, wear a mask, visit a medical facility, and make sure to inform medical staff of their recent overseas travel history.

Park Junghwan, Director of Welfare Policy, emphasized, "Since prevention and early response are especially important for infectious diseases during the summer, please ensure you are vaccinated before departure and strictly follow hygiene guidelines during travel." He added, "If you develop any suspicious symptoms after returning, immediately contact your local health center for guidance."
