#CoronaVirusUpdate from #Italy for March 27 2020. Bittersweet news. Contagion rate is declining, even though death count is rising. Resist panic. Total +#covid19 cases = 86,498, of which 66,414 infected (+4,401 = +7.2%) 10,950 recovered and 9.134 deaths (+969). /1
Death rate reflects 15-20 days ago, while new #coronavirus contagion rate = current cases. That's why infection rate is (for me) is more reliable indicator than death rate. Infection rate reflects slowdown due to lockdown. Deaths still coming in from pre-lockdown contagion. /2
