The Zika virus has been recently identified in Europe after having spread in Brazil, where its first infection was confirmed in March 2015. Despite being relatively mild, this virus is now making headlines, as it could be responsible of a large increase of microcephaly among infants. A connection that pushed Brazil to declare Zika a public health emergency.

Institutions, public agencies and authorities can tackle different kinds of crisis by using social media. In the last few months, this has been done successfully in very diverse cases, both defending the reputation of a big oil company from a journalistic inquiry, and managing the response to a terror attack within a city. Even if the type and range of crisis is hugely different, the efficacy of a prompt and wise use of social network gives clues that could be useful when dealing with infectious threats as well.

Rhett Krawit is a Californian 7-year-old kid. He survived leukaemia after a fight lasted three-and-half years that left his immune system highly compromised. He wants to go to school and he has any right to do so, but he cannot do it safely. Rhett cannot be vaccinated because his immune system is still rebuilding and the presence of unvaccinated children exposes him to diseases like measles and chicken pox, which could be lethal for him. An actual risk, since in almost one fourth of Californian schools the herd immunity has been lost because of vaccine hesitancy and refusal.

This fall, the publishing, by the Italian Minister of Health, of the alarming data showing the drop in vaccine coverage in the country, revived the ardent debate between opponents and supporters of vaccinations, especially online. Adding fuel to the fire was the death of a one-month old child by whooping cough at Sant’Orsola hospital, in Bologna, even if it is still unclear if such a tragedy actually had a significant link with the decrease of vaccine coverage or was just a coincidence.
