Impetigo is a very contagious, superficial, bacterial skin infection that easily spreads among people in close contact.
Most cases occur in children and resolve spontaneously without scarring in approximately 14 days.
Ecthyma is a deeply ulcerated form of impetigo that extends to the dermis.
It has "punched-out" ulcers with yellow crust and elevated violaceous margins.
Most cases occur in children and elderly.
It may be a de novo infection or superinfection.
While rapid antigen test is less sensitive than conventional nucleic acid amplification test (NAAT) such as RT-PCR* in detecting SARS-CoV-2 virus, “a test does not have to be perfect to be clinically useful,” said Professor Angela Caliendo during a session in IDWeek 2021 — echoing the maxim that perfect should not be the enemy of good in the pandemic era.
Invasive fungal infections, particularly those caused by Candida species, are common in hospitalized, immunocompromised, or critically ill patients and are associated with considerable morbidity and mortality.
A rapid and affordable test for diagnosing COVID-19 outside the walls of the healthcare units could improve case-finding, contact tracing, and infection control, says an expert during a pre-ECCMID 2021 session.
