The Ministry of Foreign Affairs (MOFA) on Tuesday issued a gray travel alert for Singapore, in light of a recent spike in Zika infections there.
The ministry advised Taiwanese nationals, especially pregnant women and those planning to get pregnant, to pay attention to environmental cleanliness and avoid going to mosquito-infested locations such as construction sites and open areas, if they must visit Singapore.
As of Aug. 28, 41 cases of locally transmitted Zika virus infection had been confirmed in Singapore, the country's Ministry of Health and National Environment Agency said Sunday.
It said all the patients were residents or workers in the Aljunied Crescent/Sims Drive area, 34 of whom had recovered, while seven were still hospitalized.
Under the MOFA's four-color coded system, the highest level is red, followed by orange, yellow and gray.
A gray alert advises people to pay extra attention to safety issues.
According to health authorities, adults infected with the Zika virus show only mild symptoms, but infected pregnant women could give birth to babies with microcephaly -- a condition in which a child is born with a smaller-than-normal head and impaired brain development.
The symptoms of a Zika infection include fever, mild headache, skin rash, joint pain and conjunctivitis.
