After Decades, Mosquito carrying Zika virus found in Chile

The mosquito that transmits the Zika virus has been found in the South American country for the first time in six decades, Chile’s health ministry said.

The presence of the Aedes Aegypti mosquito in Chilean continental areas was reported on Monday (April 18).

U.S. health officials recently said there’s no longer any doubt Zika can cause babies to be born with abnormally small heads and other severe brain defects.

Earlier, Chilean officials had declared that they had registered the first locally acquired case of the Zika virus, which was sexually transmitted within Chile.

Aedes Aegypti has also been detected in the Easter Island territory in the Pacific more than 3,500 kilometres from Chile’s mainland.

Chile was, with Canada, one of just two states in the Americas said to be free of the Aedes aegypti mosquito, which carries the Zika virus.

But health minister Carmen Castillo said yesterday scientists had identified a specimen of the mosquito in mainland Chile for the first time since the 1960s.

“It is an Aedes aegypti, which means that we have to take more precautions,” she said.

The Chilean mainland is largely protected from mosquitoes by mountains and deserts.

The specimen was found in the northern city of Arica, Castillo said.
