People travel from one place to another everyday, and viruses and bacterias travel with them. I have seen on the news that a new virus has apperared, the virus of Zika. This illness is transmitted by a mosquito, it is not very serious, because it´s as a cold, you can have temperature and muscular pain. It affects especially pregnant women, whose children can have several problems in the future.
In Spain, there are some people that have that illness, but they are recovered now. In South America, it is an epidemic, and they are trying to kill the mosquito. So, what can we do? As there is no treatment, the only option is to reduce the risk of being bitten,use insect repellents, cover up with long-sleeved clothes, and keep windows and doors closed.
I hope that scientists can find a cure or a vaccine for that illness, specially for pregnant women.
