Brazil hosts the first Olympic Games in South America on August 5-21 in Rio de Janeiro.
Rousseff said she believed in "great awareness from sports authorities, with respect to the fact that this situation does not threaten the Olympics. We think we can have considerable success in mosquito extermination before the Olympics," as quoted by A Tarde daily.
The current Zika outbreak originated in Brazil in the spring of 2015, spread across Latin America and gained widespread media attention as confirmations of first cases emerged in Europe and the United States in recent weeks.
The World Health Organization (WHO) declared the outbreak a public health emergency last week after the virus spread across dozens of countries and first cases of Zika’s sexual transmission emerged.
