There may be a link between the recent hot and dry winter and spring in Brazil and the outbreak of the Zika virus, preliminary research suggests.
"The extreme temperature and drought are due to a combination of the El Nino phenomenon and the climate changes of recent years," researcher Shlomit Paz, from the department of geography and environmental studies at the University of Haifa in Israel, said in a university news release.
