Re-infection of SARS-CoV-2: A case in a young dental healthcare worker

Abstract

Reinfection with SARS-CoV-2 is a rare phenomenon. To date, there has been some cases reported from countries such as United States, Ecuador, Hong Kong, the Netherlands and Belgium. This case report presents the first case of reinfection from Saudi Arabia, and probably the first dental student to have been re-infected with COVID-19. A 24-year-old male dental student presents with reinfection after a period of three months since he was first infected with COVID-19. The signs and symptoms reported by the patient were similar in both instances, except that he developed fever only at the time of reinfection. The infection and reinfection were confirmed with a RT-PCR test reports. This report highlights how it is necessary to continue to observe all the prescriptions recently indicated in the literature in order to avoid new contagion for all health workers after healed from covid-19 or asymptomatic positive, since as seen sometimes the infection does not ensures complete immunity in 100% of cases.

Recurrence of COVID-19 infection symptoms in short time; reinfection or reactivation? Three cases of three healthcare workers and a literature review

“…The difference between prolonged shedding which leads to reactivation and real reinfection should be distinguished. One of SARS-CoV-2 features is prolonged virus shedding [ 5 ]. One of the first reported cases of recurrence of clinical manifestations was for 6 health workers from Brazil, between March 16, 2020, and April 19, 2020, when symptoms reappeared with a positive RT-PCR during 53–70 days between the two events.…”

Mild respiratory illness in SARS-CoV-2 infection after vaccination in healthcare workers

“…Disease severity changes should be considered an added value of the vaccination. Various papers published report of the findings of mild disease, the limited requirement of medical care, and easy recovery in COVID-19 in HCW after vaccination (7,8,10).…”

“…Vaccination becomes a highly effective measure for minimizing the adverse consequences of the disease. Nevertheless, post-vaccination SARS-CoV-2 infections were observed and probably related to multiple factors, including the variable vaccine efficacy and the emergence of new viral variants (7)(8)(9)(10).…”

Immunomodulatory LncRNA on antisense strand of ICAM-1 augments SARS-CoV-2 infection-associated airway mucoinflammatory phenotype

“…Vaccination efforts have significantly reduced the spread of COVID-19, although variants arising from genomic mutations pose a significant risk even among vaccinated people (Fageeh et al, 2021;Kannan et al, 2022;Vitale et al, 2021). SARS-CoV-2 gains entry via the upper respiratory mucosa, and any host factor dysregulations occurring during this interaction can result in pulmonary and/or extrapulmonary complications (Hoffmann et al, 2020;Hou et al, 2020;Olwenyi et al, 2020;Rothan and Byrareddy, 2020).…”
