Just days after the Korea Centers for Disease Control and Prevention (KCDC) reported on the fourth travel-associated Zika virus case in a traveler to Vietnam, health officials report on an additional case in a business traveler to the Philippines.

According to media reports, the 39-year-old man visited Batangas, Philippines on the island of Luzon returned home with a rash, and joint and muscle pains. He was later diagnosed with Zika.

He visited the Philippines in late April and returned home on May 4.

In early March it was reported that  a US resident who traveled to the Philippines in January contracted the virus.

Many people infected with Zika virus do not get sick. Among those who do develop symptoms, sickness is usually mild, with symptoms that last for several days to a week. Guillain-Barré syndrome (GBS), a rare disorder that can cause muscle weakness and paralysis for a few weeks to several months, is very likely triggered by Zika in a small proportion of infections, much as it is after a variety of other infections. Most people fully recover from GBS, but some have permanent damage.

Sexual transmission of Zika virus from a male partner is also possible.

Last month, the US Centers for Disease Control and Prevention concluded that Zika virus is a cause of microcephaly and other severe fetal brain defects.
