Authors’ response to the letter to the editor entitled: Co-circulation of dengue, chikungunya, and Zika viruses and cross-protection
To the editor:
Dengue, zika, and chikungunya outbreaks in Central and South America countries have presented significant challenges related to their prevention and control. From the virologic point of view, the possibility has been raised that the co-circulation of the three viruses could generate cross-protection between the three alphaviruses.
