What role do children play in household transmission of COVID-19?

A new study published in the International Journal of Infectious Diseases reviews the literature systematically. It performs a meta-analysis to assess the prevalence of pediatric COVID-19 in clusters of families, estimate the household secondary attack rate of children, and compare the transmissibility of SARS-CoV-2 in different age groups.

CDC study reveals hybrid SARS-CoV-2 spike from Delta/Omicron recombination event

The US Centers for Disease Control and Prevention (CDC) has conducted national-level genomic surveillance to identify and characterize delta-omicron recombinant genomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A total of nine genomes with a hybrid delta-omicron spike protein have been identified.

Novel approach allows islet transplants to survive and control diabetes

In type 1 diabetes, an autoimmune response attacks the pancreas's insulin-producing beta cells, leading to marked fluctuations in blood sugar levels. Lifelong daily insulin treatments are standard for patients, but replacing lost beta cells through transplants of islets, a group of cells in the pancreas, represents an attractive option.
