Coronavirus, Ilaria Capua on La7: “Old and dirty trains in Lombardy have contributed to the infection. Virus weakened by the heat? No, it evolves”


We in the present are experiencing the result of what we did 15 days ago. The behaviors that we have put in place work and we must continue to use these virtuous behaviors until the virus returns to circulate under trace without bothering anyone, or because herd immunity will develop or because there will be a vaccine“. They are the words of Ilaria Capua, director of the University of Florida’s One Health Center of Excellence, during the broadcast “Dimartedì”, on La7.

On the possibility of a second wave, the virologist explains: “It is the virus that peeps through the meshes of the defenses that we have opposed to the circulation of the virus itself. Then, it is we who, through our behavior, can facilitate the return of the virus. But I guarantee you that, if we continue to be careful and observe certain behaviorslike hand washing and the safe distance then there may not even be a second wave“.

And he points out: “The virus does not weaken in the heat. There are two factors that have nothing to do with each other. The virus is weakened if its engine starts running differently. We see this with the genetic sequences of the virus, because when the virus gets worse or less bad it carries a tattoo. That the virus can circulate with greater difficulty outdoors is with higher temperatures it is possible, but in reality in these conditions the virus can lose its infectious load. Unfortunately the virus will not go away. Now it has found a new species, which is us “.

Capua adds: “I believe covid is manifesting itself as a conditioned disease. Just look at some big cities, where the situation is much more complicated than in others. I think, for example, of the transport network: one of the best public health operations that can be done is to set up the train network that goes around Lombardy, Because I am old, dirty trains, which most likely contributed to spreading the infection. This catastrophe highlighted some weaknesses that need to be resolved for a new intelligent restart. We also know – he says – that this disease is much more serious in the most polluted cities, so there is a component of the pollution. So, we need to understand what pollution is giving us the most problems, break down information, try to make proposals and make investments that also support public health. ”
