[Atypical clinical presentation of flavivirus. Case report].

The first report of chikungunya virus (CHIKV) in Mexico was in may 2014, in Jalisco, and has disseminated along the country in such a way that now is considered a relevant emergent vector-transmitted infection. It is clinically diagnosed by abrupt onset fever, asthenia, arthralgias, myalgias, headache and rash. In the clinical case, we described a women from Guerrero that had pulmonary symptomatology associated to CHIKV, which is an atypical clinical presentation that has been reported only in a hundred cases worldwide. In the epidemiological context the only known tool that we have to prevent the disease is the eradication of vectors because we lack population immunity, thus the importance of avoiding water accumulation and using protective gear. In Mexico we are acting through media advertisements in order to avoid, in first place the acute infection, which in severe cases can cause death, and in second place the chronic complications.
