Covid variants, in the race to fight them Italy is behind

He who seeks, finds. A proverb that is also valid in times of pandemics and in particular for the identification of viral variants of Sars-Cov-2. Without bothering the ‘Denmark case’, where 15% of positive swabs are analyzed entirely to understand which virus we are facing, for Italy the minimum target of 5% set by the World Health Organization is a distant mirage.
