On September 10, 2016 the French pharmaceutical company that produces the dengue vaccine, the only one of its kind in the world at the moment, sold 1 million vaccines in Mexico alone. However, the vaccine is only present in the private sector. That is, the vaccine is only available via doctors and clinics, and not yet available to public health institutions.
In December 2015, the World Health Organization (WHO) and the Pan American Health Organization issued an alert warning of the zika virus infection. The virus is a mosquito-borne disease that causes a fever, headaches, conjunctivitis, etc. Its clinical manifestation is similar to the dengue fever, which is also a mosquito-borne illness.
