The World Health Organization (WHO) warned on Monday that the mosquito-borne Zika virus is expected to spread to all countries in the Americas - with the exception of Canada and Chile.
Speaking in Geneva, Director General of the WHO Margaret Chan said she was "very concerned" by the outbreak and by the possibility that it could lead to "neurological syndromes" - although she gave no further details.
Cases in Brazil
The virus is suspected of causing brain damage to babies born in Brazil. Since October, 3,500 babies in the country have been diagnosed with microcephaly, a debilitating condition which causes the heads of newborn babies to be smaller than normal. This results in abnormalities including disruption of motor skills, speech and mobility.
Of the cases in Brazil, 49 babies died from congenital malformations. Of these five have been linked to the Zika virus.
While Brazil has seen the largest number of cases in the Americas, Zika has also been detected in Colombia, El Salvador (photo of fumigation) and Panama. The virus was detected in three people in New York last week.
Zika has been compared to a mild form of dengue fever but no medicine or vaccine exists to treat the virus which causes symptoms including rash, fever, pink eye and joint pain. The only cure known so far is rest.
The WHO advised women who plan to travel to areas where the virus has been detected to consult healthcare providers before traveling and afterwards.
Virus origins
The virus was first reported in Africa, Asia and the Pacific before moving to the Americas last year. It has spread to some 20 Latin American and Caribbean countries. Brazil has been the hardest hit.
Zika can be transmitted through blood and has been isolated in human semen.
The WHO said more evidence was needed before it was known if the virus could be sexually transmitted.
