Pregnant women urged not to travel to Florida after Zika cases detected

Pregnant women have been advised not to make unnecessary trips to Florida after the first cases of the Zika viruses appeared in the US state.

So far, four cases have been detected in Florida - home to perennially popular tourist attractions like Disney World, Universal Studios and SeaWorld - and are believed to be the first cases of the disease actually being transmitted from within the US. Until now, the infection - which is carried by mosquitos - has been mostly spread by travel to Latin America and the Caribbean, where the disease is most prevalent, or by sexual transmission. Contracting Zika results in only a slight illness in most people, but the virus is believed to cause profound brain defects in newborns (the most common condition being microcephaly) - hence the danger to pregnant women.

In the last four months, authorities have recorded close to 4,000 cases in Brazil in which the mosquito-borne Zika virus may have led to microcephaly in infants. Microcephaly results in newborns with abnormally small heads and is associated with various disorders including decreased brain development. According to the World Health Organization (WHO), the Zika virus outbreak is likely to further spread in South, Central and North America. At least twelve cases of Zika in the United States have now been confirmed by the CDC. (Photo by Mario Tama/Getty Images)

There is no treatment or preventive vaccine for Zika, and, with the Rio Olympics due to start next weekend in the midst of a continental Zika crisis, the UK authorities recently advised pregnant women to avoid travelling to the Games. Now, Public Health England has updated its travel advice about Florida, saying:

"The risk in Florida is considered moderate based on the number and spread of cases and their demonstrated ability to implement effective control measures for similar diseases such as dengue - a virus transmitted by the same mosquito. "Pregnant women should consider postponing non-essential travel to affected areas until after the pregnancy. At present, only a zone of about one square mile in Miami-Dade County is considered at risk of active transmission."

Microcephaly is a birth defect linked to the mosquito-borne Zika virus where infants are born with abnormally small heads. The Brazilian city of Recife and surrounding Pernambuco state remain the epicenter of the Zika virus outbreak, which has now spread to many countries in the Americas. A group of health experts recently called for the Rio 2016 Olympic Games to be postponed or cancelled due to the Zika threat but the WHO (World Health Organization) rejected the proposal.

"There is no specific treatment for Zika and it usually wears off naturally after two to seven days. "After a diagnosis patients are cared for by their GPs if needed. There is extremely low risk of contracting Zika virus in the UK as the mosquito that transmits the infection is not present in the UK, however it can be spread by sexual transmission."

It can all be pretty confusing, so the HSE has a designated section of its website devoted to advice about Zika and travel, while the Irish Department of Foreign Affairs has more advice for pregnant women and those trying to become pregnant.
