The virus that causes fetal brain atrophy is at risk of spreading throughout the Americas

Zika, a virus that causes brain damage in children, is still in the womb, which can spread throughout the United States while humans have not found effective vaccines to prevent.

According to the World Health Organization (WHO), Zika virus is transmitted from human to human through an intermediary that is a mosquito. They can spread in nearly all Americas, except Canada and Chile. Meanwhile, the Brazilian Ministry of Health said Zika caused deformity of the fetus called microcephaly. Mothers with this virus will produce babies with a smaller brain than normal, Reuters reported.

Brazil has reported 3,893 suspected cases of small headaches, 30 times more than the number of cases each year since 2010. This is equivalent to 1 to 2% of children born in the state of Pernambuco. , the region most heavily affected in Brazil, WHO announced.

Zika is unlikely to erupt like the Ebola epidemic in West Africa in 2014 but it is still a testament to the dangers of diseases that little humans know. Trudie Lang, a professor at the University of Oxford, said: "We don't have a drug yet and there is no vaccine to prevent Zika. This is exactly what we encountered with the Ebola pandemic. Finding the vaccine Please be an urgent request ".

Zika virus was first found on a monkey in Zika forest, near Lake Victoria, Uganda in 1947. Cases of illness have appeared in Africa, Southeast Asia and Pacific islands. However, scientists have not been able to determine why this virus appears in Brazil.

In August this year, Brazil will host the Olympics in Rio de Janeiro. Pregnant women are forced to stay away from the area if they do not want to be afraid of mosquito bites. WHO also recommends that pregnant women plan to go to places where epidemics are needed to take good care of their health.

Clinical symptoms of small head disease are usually mild and similar to dengue, which is transmitted by the mosquito. Many people fear Zika will spread around the world like the prevalence of dengue. More than one-third of the world lives in areas that are at risk of dengue infection, suggesting that a similar number of people are within Zika's scope of infection.
