It is not a simple flu. I was wrong, but in one thing I was right: leap years are ill fated. When I wrote the previous article about Covid-19 diffusion in Italy, that was the situation: 378 people had been infected, 12 had died and all of them suffered from serious pathologies. Nothing that serious, I believed; but things have worsened soon. At the time being this is the updated bulletin: 5883 infected, 1247 new cases since yesterday, 589 have recovered so far and 233 have died. In only 10 days. It is not a simple flu.
Let’s explain why. 1) A normal flu is seasonal, it mutates, therefore, it is always slightly different from the virus of the year before, that is why we are not completely immune, even if we have been infected. Being a variant of the flu virus of the year before, we are only partially immune. Each of us has a different immunity rate, which depends on age, health conditions etc. . We are not immune to Covid-19 and it is very contagious.2) We know how the seasonal flu virus works and we produce new vaccines every year, because, as we have just said, the flu virus mutates. We have no vaccine for Covid-19. 3) We have medicines to cure or relieve flu symptoms, while there is no cure for Covid-19. Not yet. 4) A normal flu may sometimes degenerate into a bacterial pneumonia, which, however, may be treated with antibiotics, for example. If Covid-19 reaches the lower parts of the respiratory system, it may cause a viral pneumonia, for which there is no treatment. In the case the virus develops to that stage (10% of the patients), hospitalization is required and the most serious cases need ICU. And this is the problem, because the average stay in ICU is usually 2/3 weeks. Too long.
Beds in hospitals are not infinite, they are at the limit of total saturation and we may get to the point when there will be none left, hence, we won’t be able to treat patients properly from the complications of the infection. So what can be done? Well, only following the health protocol, staying at home to avoid feeding the spread of the virus from person to person and hope that it will stop sooner or later. We must make the virus less contagious so that to decrease the number of infected people and give everybody the opportunity of being cured.
In the meantime our life has changed. The country is reacting mostly paralyzing any activity and this has and will have serious consequences on our economy. Schools have been closed till (at least ) March 15th. It is today’s news that those living in Lombardy and other 14 provinces won’t be allowed to leave their sites till April 3rd. It is as if we were caught in a limbo and we can do nothing but give up any social life and wait. Things are going so fast that I bet this article will be old by the time I post it, that is: now.
