Although the data are not available, it seems that the risk to the fetus of asymptomatic reinfection is small,3" and certainly it is far less than that of primary rubella. In the rare cases of symptomatic reinfection viraemia may be presumed to have occurred, putting the fetus at appreciable risk.9 An antibody response may be confidently ascribed to reinfection if two or more previous positive ...

COVID-19 reinfection is an emerging concept in the evolution of this pandemic. Protection conferred from active disease and vaccinations are not fully known. Other patient related factors need to be identified investigated. The current study describes patients’ profile identifies possible risk that significantly contribute likelihood outcomes. This a single center retrospective on reinfected pa...

Recent evidences show that individuals who recovered from COVID-19 can be reinfected. However, this phenomenon has rarely been studied using mathematical models. In paper, we propose an SEIRE epidemic model to describe the spread of with reinfection. We obtain important thresholds [Formula: see text] (the basic reproduction number) and (a threshold less than one). Our investigations when text],...

In recent years, the utility of serum-based diagnostic testing for Lyme disease has improved substantially; however, recovery by culture of the bacterium from skin biopsies of suspected patients is still the only definitive laboratory test. Reinfection of patients has been assumed to occur but as yet has not been documented by serial isolates from the same person. We present a case of culture-c...

To study the natural history of rotavirus infection and to determine the protection it confers against reinfection and diarrhea, 200 newborns in Guinea-Bissau were prospectively followed for up to 2 years. Rotavirus was detected in stool specimens collected weekly. By age 2 years, the incidence of primary rotavirus infection was 74%. In the first 3 months of life, 17% of the infections were dia...
