To provide correct information about dengue fever and Zika virus infection to Japanese overseas travelers, we analyzed the knowledge that people have regarding dengue fever and Zika virus infection. For this purpose, we asked Japanese people (n: 500) who were planning to travel to a developing country in the next 6 months to complete a questionnaire on the internet.

From the results of the survey, we found that more than 80% of subjects had heard about dengue fever and Zika virus infection. Of these subjects, those who knew that the diseases were 'transmitted by mosquitos' were 82.8% for dengue fever, and 59.2% for Zika virus infection.

On the other hand, the fact that 'The mosquitos bite during the daytime' was known by only 20% of subjects regarding dengue fever, and 14% regarding Zika virus infection, which were very low percentages.

In addition, subjects who knew that 'Zika virus can be sexually transmitted' comprised 13.2% of the total, and 'Zika virus may affect the fetus' comprised 23.8%. These were also very low percentages.

The information that mosquitos that mediate dengue fever and Zika virus infection bite during the daytime will be important for overseas travelers, to implement preventive measures. In the future, it is necessary to provide the correct information to Japanese travelers, including information on the sexual transmission of Zika virus and its effects on the fetus.
