Dear Sir,

The present Zika virus infection outbreak in South America has become a global concern. In this year's Olympic Games held in Brazil, the fear of Zika virus is a big issue for discussion.[1],[2] Indeed, the concern about the health of visitors to Brazil during the Games is widely discussed. On the basis of the previous report by Ximenes et al.,[3] the estimated risk of another important arboviral disease, dengue, was done. Ximenes et al. found that “the expected number of symptomatic and asymptomatic dengue cases among tourists will be 23 and 206 cases, respectively.”[3] Here, the authors use the same mathematical method for estimation of the expected risk for Zika virus infection. To modify the mathematical model, simulation was based on the recent data from the Wikan et al.[4] on the concurrent infection between dengue and Zika virus infections. On the basis of the present study, the expected worst-case situation is “an incidence of 4.40 and 39.382 per 100,000 individuals for symptomatic and asymptomatic Zika virus infections.” Of interest, this derived rate is significantly lesser than that estimated by Ximenes et al.[3] for dengue. This can confirm the recent note that “Zika is not a reason for missing the Olympic Games in Rio de Janeiro.”[5]
