India has reported its first three cases of the Zika virus. Those affected include two pregnant women who delivered healthy babies.
"There is no need to panic," Dr. Soumya Swaminathan, a top Health Ministry official, told reporters.
The Wolrd Health Organization (WHO) released a statement saying that the three cases, which were reported to the agency on May 15, were detected through routine blood tests in a hospital in Ahmedabad, Gujarat.
Swaminathan added that none of the patients had traveled overseas and, therefore, contracted the infection locally. The Zika virus is transmitted by the Aedes aegypti and Aedes albopictus mosquitoes.
The majority of people infected by the Zika virus never actually get sick. Although the virus only causes mild symptoms in most people, it has caused defects in babies born to Zika-infected mothers. Complications include microcephaly and Guillain-Barre syndrome.
The WHO's report described the first three Zika cases and provided evidence on the circulation of the virus in India.
"These findings suggest low level transmission of Zika virus and new cases may occur in the future," the WHO said in a statement. "Efforts to strengthen surveillance should be maintained in order to better characterize the intensity of the viral circulation and geographical spread."
The WHO recommended that governments continue working to control mosquitos.
