An unnamed San Francisco resident tested positive for the Zika virus in February, health officials announced earlier this week. The California Department of Public Health apparently confirmed the infection on February 4, however the information was only made public after a separate infection in Napa County was detected.

Health officials have hastened to note, reports the Chronicle, that the unnamed resident contracted the virus while traveling in Central America and has since fully recovered. It is unknown whether the person is male or female, but officials have stated that unlike in the case of the Napa County patient, the San Francisco resident was not pregnant.

The Zika virus, as you surely recall, has been linked to cases of the birth defect microcephaly — although scientists can't say conclusively that it is the cause. A healthy person infected with the virus has little to worry about, as the symptoms frequently pass within a week. The virus is mainly transmitted via mosquito, however there have also been confirmed incidents of transmission via sexual contact.

On February 1, the World Health Organization declared the spread of the Zika virus to be an international public health emergency. At present, there are no known cases of a person contracting the disease from a mosquito within the United States.
