The Korea Disease Control and Prevention Agency recently announced on the 4th that a case of Zika virus has occurred in the country. This is the first case of Zika virus in two years. The Zika virus is usually transmitted by forest mosquitoes, and infection causes the skin to turn red. Symptoms include rash, fever, conjunctival injection, and muscle aches.
According to the Korea Disease Control and Prevention Agency, a man in his 40s, referred to as Mr. A, who visited Bali, Indonesia, recently tested positive for the Zika virus. It is presumed that Mr. A was infected after being bitten by mosquitoes locally. His condition is said to be improving.
The Zika virus is transmitted by forest mosquitoes and can also be spread through blood transfusions and sexual contact. The incubation period is 3 to 14 days. The mortality rate is low, and recovery occurs with sufficient rest. Rarely, neurological complications may arise. If infected during pregnancy, it can lead to preterm birth or stillbirth, or the child may be born with microcephaly. Microcephaly is a condition where the brain is underdeveloped and small.
Globally, there were 56,601 reported cases of Zika virus in 2023, compared to 44,597 cases last year and 12,660 cases up to May this year. Countries with reported cases from 2023 to May of this year include Brazil (108,897 cases), Bolivia (1,496 cases), Argentina (1,252 cases), Thailand (1,106 cases), India (151 cases), and Singapore (47 cases).
In Korea, there have been 40 reported cases of the Zika virus since 2016. Among these, 39 cases were imported from overseas, including the Philippines, Thailand, Vietnam, Maldives, and Indonesia. One case was infected in a laboratory. The last infected case was recorded in 2023 with two individuals. The Korea Disease Control and Prevention Agency noted, "The Zika virus incidence is high in Southeast Asia, a region preferred by our citizens, so caution is necessary."
Since there are no vaccines or treatments for the Zika virus, avoiding mosquito bites is the top priority. The Korea Disease Control and Prevention Agency urges travelers to countries where the Zika virus is present to follow prevention guidelines. They should prepare mosquito repellents and mosquito coils, and stay in accommodations with mosquito nets or screens. While traveling, it is advised to avoid jungles and mountains, and wear long sleeves and long pants.
After returning from Zika virus outbreak countries, individuals should watch for symptoms for two weeks. If symptoms appear, they should visit a medical institution immediately and inform them of recent travel abroad. It is advisable to avoid donating blood and sexual contact for four weeks after returning.
