Pediatric patients with prior COVID-19 or MIS-C are not protected against Omicron

Researchers calculate the impact of consuming ultra-processed foods on obesity risk

Research building on the national Overcoming COVID-19 Study, led by Boston Children’s Hospital, and the hospital’s own Taking On COVID-19 Together group, provides evidence that children who have already had COVID -19 (or the inflammatory disease MIS-C) are not protected against the new Omicron variant. Vaccination, however, provides protection, according to the study. The findings, … Read more

SARS-CoV-2 genome analysis could boost disease surveillance

Disasters can disrupt access to medications for opioid use disorder in vulnerable communities

Continuous monitoring of the evolution of the virus that causes COVID-19 as the pandemic progresses could strengthen disease surveillance systems and help prepare for new variants, a study has found. Last year, the World Health Organization (WHO) indicated that identifying the genetic makeup of the virus that causes COVID-19 called SARS-CoV-2 could play a vital … Read more
