Zika Outbreak: Thousands of Brazilian Babies Born with Birth Defects

According to new figures, more Brazilian babies were born with abnormally small heads to mothers infected with the Zika virus.

There have been 3,893 cases of microcephaly since October, when the authorities first noticed a surge, up from 3,500 in last week’s report.

The Zika virus is transmitted by the bite of the Aedes aegypti mosquito, which also spreads dengue and chikungunya.

Brazil is experiencing the largest known outbreak of Zika.

The Zika virus has already killed five babies in the country, said the health ministry. Another 44 deaths are being investigated to determine if they were caused by Zika.

Last week, the Brazilian Health Minister Marcelo Castro said a new testing kit was being developed to identify quickly the presence of either of the three viruses.

Marcelo Castro also announced extra funds to speed the development of a vaccine for Zika “in record time”.

At the moment the only way to fight Zika is to clear standing water where mosquitoes breed.

There has been a sharp rise in the number of cases of Zika in several other Latin American countries.

In Colombia, more than 13,500 cases have been reported.

“We are the second country [in Latin America] after Brazil in the number of reported cases,” said Health Minister Alejandro Gaviria.

He has advised women in the country not to get pregnant for the rest of the outbreak, which he said could last until July.

In Bolivia, the authorities have reported the first case of a pregnant woman diagnosed with Zika.

“She has not travelled outside the country. This is a home-grown case,” Joaquin Monasterio, director of Health Services for the eastern department of Santa Cruz told the AFP news agency.

The US Centers for Disease Control and Prevention (CDC) issued an alert on January 15 advising pregnant women to avoid travelling to Brazil and other Latin American and Caribbean countries where outbreaks of Zika have been registered.

The travel alert applies to Brazil, Colombia, El Salvador, French Guiana, Guatemala, Haiti, Honduras, Martinique, Mexico, Panama, Paraguay, Suriname, Venezuela and Puerto Rico.
