Molecular Study of COVID-19 and its Relationship to Pityriasis Rosea

Abstract

Background: A new type of coronavirus family (SARS-CoV-2), that has been detected in individuals with several clinical symptoms named (COVID-19), was recognized as a pandemic on March 11, 2020. Numerous researches have been conducted on manifestations of skin disease related to COVID-19, i.e. rashes, pityriasis rosea (PR), vascular markings, and lesions as pimple-like. 

Aim: This study aims to find out if the Coronavirus can affect (PR) development which also can be considered as a trigger and symptom for other types of infections.

Material and Methods: A case series descripting the dermatological finding of COVID-19 in Thi-Qar Governorate, a collective sample taking from
inpatients, outpatients, the emergency unit of Al Hussein Teaching Hospital, and inwards of Al-Shefaa’ Isolation Hospital. The study has been done over
a four-month period (June-September, 2020.)

Results: 19 patients (10 females and 9 males), who have infected with Coronavirus and were suffering from (PR), are included in this study. The highest percentage of females 52.6% and males 47.4%. The distribution of patients according to the incidence of (PR) in typical and anomalous manners had the percentage of typical 77.9% and abnormal 21.1%. The highest percentage was in moderate Covid-19 (84.2%), while it was 15.8% in mild Covid-19. There was no significant statistical difference in mean age distribution according to gender while there were significant statistical differences according to (PR) and COVID-19 class. More studies are needed to evaluate whether or not these lesions are associated with the virus. 

Conclusion: The (PR) was one of the dermatological finding of COVID-19, that did not have a clear role in the distribution of the disease according to the background of the patients and also the severity of COVID-19. It can be triggered by COVID-19 and completely cured with the clearance of the disease. Recommendation: An accurate robust cutaneous documentation related to Covid19 is required to increase the knowledge of disease as well as its epidemiology.
