President santos we, in a way, increase. Ting a rapid something similar happened with the chikungunya, which we had at the beginning of last year. We expect this to grow, plateau, then come down. The problem with the zika virus is that nobody really knows a lot about what it is. There are some concerns about the consequences of the zika virus. In, for example, women who are expecting a baby.
