The share of the population of KSA that has been infected by Covid19 starts to be relevant to provide some sort of background immunity from people that have been infected and have recovered, at ~41,250 per million. Despite the subject is controversial, most of these studies [2] , [3] show that people who have recovered from infection have Thus, associated with a much more widespread outbreak, over the last two months the percentage of deaths between closed cases has increased in KSA, from 0.83% [1] to the latest 1.24%, which is still in between the world's smallest. The total number of closed cases is not available for the UK in any of the databases. We noticed [1] that the above data of fatality only refer to Covid19 medium-to-severe cases that required medical attention. There is an overwhelming percentage of Covid19 infections that do not require medical attention, either asymptomatic or very mild cases. If 80% of infections were mild or asymptomatic (www.who.int), by taking 20% of the 1.24% fatality rate in closed cases between the medium-to-severe Covid19 cases, the fatality rate of KSA is therefore 0.248%. As a reference, the death rate for influenza and pneumonia for KSA [1] is 49.64 per 100,000 or 0.050%. Thus, Covid19 is much more serious than the seasonal flu, but despite the spreading to large sectors of the population, KSA has been able to keep the fatality rate in between the world smallest. Covid19 infectivity and fatality are less than what was initially thought in March [4] . While the way-out from this outbreak is still uncertain, long-lasting measures must be sustainable. The path to move forward in Covid19 infection is not to limit infection through harsh restrictions enforced forever, that are everything but sustainable, and put at risk of second waves [5] , but to protect the vulnerable and offer effective hospital case for those in need of urgent help.
