ReviewA Review of the Epidemiology of Invasive Meningococcal Disease and Vaccination Strategies in North Africa.
This narrative review considers the epidemiology of invasive meningococcal disease (IMD) in North Africa and the adequacy of current preventive measures to provide guidance for future vaccination strategies. ⋯ Improving IMD diagnosis and surveillance would provide a reliable estimate of IMD burden, leading to better vaccination strategies.

The characteristics of 527 discharged COVID-19 patients undergoing long-term follow-up in China.
Almost a year after the outbreak of coronavirus disease 2019 (COVID-19), many hospitalized COVID-19 patients have recovered. However, little is known about the long-term follow-up (> 2 months) of discharged patients. ⋯ A total of 6.1% of 527 discharged patients showed RP status, which may be easier to be identified from stool samples than from other samples. Given the dropping rate of SARS-CoV-2 antibodies, reinfection may happen, especially in juvenile patients (aged<18 years). These findings have implications for the long-term management of recovered COVID-19 patients.

SARS-CoV-2 seroconversion among 4040 Egyptian healthcare workers in 12 resource-limited healthcare facilities: A prospective cohort study.
We examined Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) seroconversion incidence and risk factors 21 days after baseline screening among healthcare workers (HCWs) in a resource-limited setting. ⋯ Most seroconversions were asymptomatic, emphasizing need for regular universal testing. Seropositivity was three-fold that observed at baseline. Cumulative infections increased nationally by a similar rate, suggesting HCW infections reflect community not nosocomial transmission.
