165:. In 2016, Viboud demonstrated that a person's first case of influenza influenced their later likelihood to become infected. For example, if people were exposed to a particular strain of influenza as a child, they would be to 75% less likely to contract it in the future. Viboud has also studied how urbanisation impacts the intensity of influenza epidemics. She showed that more diffuse epidemics occur in large cities, which were less sensitive to changes in climate. In these cities people live so close together that the virus can spread easily from person to person. In an effort to better predict influenza-like illness activity, Viboud has examined whether they can be forecast using heart rate information from

that a crowd-sourced, collaborative, physician-oriented social network helped to compile early SARS-CoV-2 data, as well as helping to track the progression of the outbreak. These efforts helped to disseminate up-to-date and correct information when limited data was available. She has also investigated why there are so few cases of COVID-19 in younger populations.
