Yemen on Wednesday reported the first three cases of the novel coronavirus in the southern province of Lahj, one of whom has died, and another infection in the interim capital, Aden, in the south.
The emergency coronavirus committee of Yemen's legitimate government also said one COVID-19 patient diagnosed earlier in Taiz province had died.
This takes the total count in areas under control of the government to 25 infections with five deaths.
The Iran-backed Houthi militias, which control the capital Sanaa, have so far reported one infection, a Somali national who was found dead in a hotel.
The five-year war has shattered the health system and left Yemen's population weakened by widespread hunger and disease.
Aid groups fear a devastating outbreak due to inadequate testing and a shattered health system. According to WHO only 200 tests with results have been delivered nationwide.
