Bangkok - A new Zika outbreak has been reported in Thailand, with 11 confirmed new cases, the Department of Disease Control said on Tuesday.

In Thailand's northern province of Pichit, 330 kilometres away from Bangkok, 11 people were infected with the Zika virus last week.

No exact cause has been determined, but the ministry has cautioned the public of the spread of Zika during the current monsoon season, as more mosquitoes, carriers of the virus, are expected to breed.

None of the 11 people with the Zika virus is pregnant, the department confirmed.

In September, Thailand confirmed Zika-linked microcephaly in two newborns, the first cases in South-East Asia, and the second in the world after Brazil.

Pregnant women who have contracted the Zika virus can give birth to children with with microcephaly, a birth defect where a baby's head and brain are smaller than usual.

There is currently no cure for microcephaly.

Up to 81 people across Thailand have been infected with the Zika virus since January 1, many of whom have recovered, the department said.
