The fight against the epidemic of Zika, stretching in Latin America, will be “a long way” warned Tuesday the director general of the World Health Organization (WHO), Margaret Chan, traveling in Brazil, the country most affected.
Brazil, the most affected country, already has over a million and a half cases of Zika virus since 2015, and WHO is expected to spread “explosive” in the Americas, with 3 to 4 million cases this year.
the epidemic causes even more concern than the Olympic games to be held in August in Rio de Janeiro.
Start February, the Organization had estimated that a possible link between Zika and explosion cases of microcephaly, severe congenital malformation, should be studied and therefore constituted “a public health emergency of international concern”.
Experts will know in a few weeks if the Zika virus is a cause of microcephaly and Guillain-Barré syndrome (neurological disease that can cause irreversible paralysis or death), but large-scale clinical trials vaccines should not start until at least 18 months, recently warned the WHO.
Almost 70 years after the discovery of Zika in a monkey in Uganda, there is no vaccine or treatment specific or rapid diagnostic test.
