Overview

Zprávy o výskytu opakovaných infekcí virem SARS-CoV-2 narůstají. Studie se proto zaměřila na výskyt reinfekcí u potvrzených případů onemocnění covid-19 v České republice. V období od 1. 3. 2020 do 9. 11. 2020 bylo nahlášeno celkem 362 084 případů s prvními příznaky do 31. 10. 2020. Bylo nalezeno celkem 28 případů opakovaných symptomatických onemocnění covid-19, z toho 11 u mužů a 17 u žen. Věkové rozpětí osob bylo 25–80 let, medián 46 let. Interval mezi první a druhou epizodou onemocnění byl v rozmezí 101–231, medián 201,5 dní. Všechny osoby byly v obou epizodách symptomatické infekce vyšetřeny metodou RT-PCR. Celkem 26 pacientů (92,9 %) bylo v období mezi epizodami onemocnění covid-19 testováno s negativním výsledkem. Symptomatické případy reinfekcí tvoří téměř 0,2 % ze všech osob v riziku z analyzovaného souboru. Většina osob s reinfekcí v souboru měla v obou epizodách mírný průběh, pouze 3 epizody byly střední či těžké. Řada dalších reinfekcí tudíž vůbec nemusela být diagnostikována. Stručně řečeno, reinfekce covid-19 jsou možné a nejsou výjimečné.

Klíčová slova:

COVID-19 – koronavirus – virus SARS-CoV-2 – reinfekce
