Koroonaviiruse leviku arvestamisel lähtutakse üldjuhul riigis registreeritud positiivsete testide arvust. See ei pruugi siiski anda parimat pilti viiruse levikust. Kui vaadata Covid-19 nakatunute arvu miljoni elaniku kohta, pilt muutub. Selles mõõtkavas on kõige ohtlikumad riigid väikese elanike arvuga San Marino, Vatikan ja Fääri saared (mis teadaolevalt riik siiski pole, kuid sel pole vist siinkohal tähtsust), kus on registreeritud üle 1000 nakatumise miljoni elaniku kohta.

Järgmises kategoorias, üle 500 nakatunu ühe miljoni elaniku kohta, on neli riiki: Lichtenstein, Island, Andorra ja Itaalia. Jällegi, neist kolm ei kuulu rahvaarvult just maailma suurimate riikide hulka.

Eesti kuulub kolmandasse kategooriasse, kõrge nakatunute suhtarvuga riikide hulka, kus miljoni elaniku kohta on registreeritud 100 – 499 juhtumit.

Väikese nakatunute arvuga riikide puhul tuleb siiski arvestada, et see võib viidata pigem madalale või puuduvale testimisvõimekusele.
