COVID-19 patients present with various cutaneous manifestations that are habitual in other viral infections. The vesicular eruption has an appearance similar to varicella and has been described as infrequent but specific to SARS-CoV-2 infection. The differential diagnosis has also been proposed with other pathologies with a similar appearance, such as herpes simplex, herpes zoster, miliaria, impetigo, ecthyma, and coma blisters.
Parvovirus B19 can also produce vesicular exanthems that are very similar to those being reported during the COVID-19 pandemic. We present the case of a child who posed the differential diagnosis of a vesicular exanthema caused by SARS-CoV-2 due to both the symptoms and the epidemiological setting.
An 8-year-old boy presented with a papulovesicular exanthem on the trunk and extremities that had developed over a period of 3 days [Figure 1]. On the 4th day after the onset of skin symptoms, the patient developed a fever, cough, and general malaise. His mother worked as a nurse in a pneumology department and had been in contact with COVID-19 patients. His sister presented with fever and perniosis-like lesions on toes that had developed over 7 days.

Blood tests, which included biochemical, hemogram, coagulation test, and urinalysis, showed no alterations. The serologies for parvovirus B19, Epstein–Barr virus (EBV), cytomegalovirus (CMV), measles, parotitis, rubella, herpes simplex, varicella-zoster, HIV, rickettsiosis, and hepatitis B and C, as well as the polymerase chain reaction (PCR) for enterovirus (coxsackievirus, poliovirus, and echovirus), CMV, and EBV, were all negative. The reverse transcriptase-PCR of the nasopharyngeal swab and total antibody (immunoglobulin [Ig] M + IgG) SARS-CoV-2 rapid test were negative, as was the PCR for other respiratory viruses.
His sister developed a rash with slapped cheek appearance, so we decided to repeat the serologies. Fifteen days after the appearance of skin symptoms, new serologies were performed including specific SARS-CoV-2 IgA + IgM and IgG antibodies. Serologies for parvovirus B19 IgM and IgG antibodies came back positive. Due to the seroconversion of the parvovirus B19 antibodies, the papulovesicular exanthem was attributed to parvovirus B19. The serologies for the rest of the viruses were negative.
Parvovirus B19 can cause different cutaneous manifestations, such as infectious erythema with a slapped cheek appearance, maculopapular rashes, or petechial rashes such as glove and sock syndrome. However, microvesicular exanthems with a varicelliform appearance have been described in parvovirus B19 infections. This exanthem caused by parvovirus B19 suggests a differential diagnosis with the recently described exanthem similar to varicella in COVID-19 patients., Therefore, although the vesicular eruption arising during the COVID-19 pandemic is rare and specific attributed to infection by SARS-CoV-2, we nonetheless encourage the carrying out of serologies for other viruses that habitually produce cutaneous manifestations, such as parvovirus B19 [Table 1].

In conclusion, although this vesicular eruption is emerging during the COVID-19 pandemic, it is necessary to demonstrate its etiology with microbiological diagnostic techniques because other viruses may cause these exanthems.
