Staphylococcus aureus Colonization in Healthy Children during the First Year of the Severe Acute Respiratory Syndrome Coronavirus 2 Pandemic.

The early severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic was temporally associated with a reduction in many childhood infections, although the impact on bacterial colonization is unknown. We longitudinally assessed Staphylococcusaureus colonization prior to and through the first year of the pandemic. We observed a decline in methicillin-resistant Staphylococcus aureus colonization associated with SARS-CoV-2 prevention mandates.

Recognizing a MIS-Chievous Cause of Acute Viral Gastroenteritis.

Historically, children evaluated for vomiting and diarrhea secondary to viral enteritis have symptoms lasting 2-4 days and respond to supportive care, including oral rehydration and anti-emetics if required. Recently, within a 14-day timespan, we encountered three children with severe diarrhea who rapidly became dehydrated and went into hypotensive shock. Although SARS-CoV-2 molecular tests were negative by nasopharyngeal swab, all were later found to have MIS-C. This small case series underscores features reported in previous larger studies and emphasizes the rapid clinical evolution of this condition. We highlight the importance of early recognition of cardinal laboratory findings characteristic of MIS-C (i.e., lymphopenia, markedly elevated acute phase reactants, and hypoalbuminemia). We also show serologic evidence that the pathophysiological mechanism of SARS-CoV-2 related diarrhea may differ from other causes of dehydrating vomiting and diarrhea, with no serologic evidence of villus cell injury.

The Indirect Impact of the SARS-CoV-2 Pandemic on Invasive Group a Streptococcus, Streptococcus Pneumoniae and Staphylococcus Aureus Infections in Houston Area Children.

Masking and social distancing have been adopted to mitigate the severe acute respiratory syndrome coronavirus 2 pandemic. We evaluated the indirect impact of severe acute respiratory syndrome coronavirus 2 prevention strategies on invasive Staphylococcus aureus, Streptococcus pneumoniae (pneumococcus) and Group A Streptococcus in Houston area children. We observed a decline in invasive pneumococcal disease and invasive Group A Streptococcus temporally associated with social distancing/masking/school closures.
