With some 100 million Americans fully vaccinated, the U.S. is relying on a patchwork network of vaccine monitoring systems that lack the breadth and depth of large, population-based programs, experts said.
Nearly 60 organ transplants have been performed after the coronavirus “basically destroyed” patients’ hearts and lungs.
The once-promising therapy that infuses blood plasma from recovered covid-19 patients into newly infected people, theoretically to boost immunity, has suffered setbacks. But some proponents say it’s too early to abandon the treatment.
As experts race to get an approved test for covid variants, officials are severely restricted from sharing information about the cases. That makes it harder to protect others.
The first confirmed U.S. case of SARS-CoV-2 being transmitted through an organ transplant has prompted calls for updated transplant protocols and additional testing of samples from deep within donor lungs.
El incidente parece ser aislado, el único caso confirmado entre casi 40,000 trasplantes realizados en 2020. Pero ha generado el pedido de que se hagan pruebas más exhaustivas a los donantes.
Hundreds of Americans suspect they contracted covid early in the pandemic and recovered, only to get infected again months later. But because the U.S. does so little genetic sequencing of covid samples, we don’t know much about reinfection rates.
Aunque se definen como “raras”, habría muchas reinfecciones por covid. El problema es que Estados Unidos no tiene la capacidad para hacer el análisis genético necesario para detectarlas.
Months after President Donald Trump credited monoclonal antibody therapy for his quick recovery from covid-19, only a trickle of the product has found its way into regular people. While hundreds of thousands of vials sit unused, sick patients who might benefit from early treatment have been left on their own to vie for access.
More than two dozen people who have received the new covid vaccines in U.S. hospitals and health centers suffered anaphylaxis, a potentially fatal allergic reaction. While such severe reactions are rare, experts warn that the drugstores and drive-thru clinics considered integral to the vaccine rollout must be prepared.
