China's Foreign Ministry says its embassy in Singapore has been informed by the island state's health ministry that 21 Chinese nationals in the country are confirmed to have been infected with Zika.
In a statement sent to Reuters, the foreign ministry added that the health situation was not serious and that some of them had recovered.
Meanwhile, Malaysia has confirmed the first cases of Zika in the Southeast Asian country in a woman who recently travelled to Singapore for three days on August 19.
Malaysia's health minister said the woman tested positive for Zika in her urine after she experienced a rash and fever for a week after her return from Singapore.
Health Minister Subramaniam Sathasivam said her child, who is in Singapore, also tested positive for Zika.
Singapore announced the first locally contracted case of Zika late on Saturday, and the number of diagnosed infections has grown steadily this week.
