La infección por SARS-CoV-2 proporciona inmunidad equivalente a la vacunación
La inmunidad proporcionada por una infección por SARS-CoV-2 protege a una persona contra una enfermedad grave al igual que 2 dosis de la vacuna de ácido ribonucleico mensajero (ARNm), según un nuevo estudio. Las personas que se infectaron con SARS-CoV-2 redujeron sus posibilidades de hospitalización y muerte en 88% durante 10 […]
Large Cohort Study Finds Possible Association Between Postural Orthostatic Tachycardia Syndrome and COVID-19 Vaccination but Far Stronger Link With SARS-CoV-2 Infection
Shortly after COVID-19 vaccines first became available, Tae Chung, MD, noticed something unusual at the Johns Hopkins Postural Orthostatic Tachycardia Syndrome (POTS) program, which he directs. Seven patients newly diagnosed with POTS were either medical students or physicians. They had no recent history of SARS-CoV-2 infection, which, research has suggested, […]
SARS-CoV-2 viral load and shedding kinetics
Abstract SARS-CoV-2 viral load and detection of infectious virus in the respiratory tract are the two key parameters for estimating infectiousness. As shedding of infectious virus is required for onward transmission, understanding shedding characteristics is relevant for public health interventions. Viral shedding is influenced by biological characteristics of the virus, […]
Preparing for uncertainty: endemic paediatric viral illnesses after COVID-19 pandemic disruption
Non-pharmaceutical interventions (NPIs) and societal behavioural changes during the COVID-19 pandemic altered not only the spread of SARS-CoV-2, but also the predictable seasonal circulation patterns of many endemic viral illnesses in children. Before 2020, respiratory syncytial virus (RSV) and non-pandemic influenza viruses peaked in the winter in northern and southern […]
“Tripledemia”, el ataque múltiple de virus respiratorios que satura los hospitales de niños en EE.UU. y algunos países de Sudamérica
Cuando todo hacía suponer que finalmente podíamos respirar aliviados y dejar atrás la crisis sanitaria que generó la covid, una nueva ola de virus respiratorios está volviendo a colmar las unidades pediátricas de hospitales en algunos países. Se trata -aclaran los expertos- de un fenómeno muchísimo menos grave que el […]
U.S. Could Face Tripledemic of RSV, COVID, and Flu This Year
Late fall heading into winter is known as respiratory virus season, but this year things are a little different. Three respiratory viruses are surging—RSV, COVID-19, and the flu—in what plenty of people are now calling a “tripledemic” of infectious diseases. Here’s a breakdown of what it’s like out there right now: Flu […]
Canadian Doctors Call for Mental Health and Addiction Funding for Team-Based Care
The Ontario Medical Association (OMA) and Primary Care Collaborative have called for $37.5 million in immediate funding, as well as $75 million annually for 10 years, to help primary care providers treat patients with depression, anxiety, and addiction. The recommendation is part of a four-point plan to strengthen mental health and […]
El dolor faríngeo se convierte en un síntoma dominante de la COVID-19: informes
Presentar dolor faríngeo u odinofagia es ahora un síntoma dominante de la infección por SARS-CoV-2, mientras que la fiebre y la anosmia (pérdida del olfato) se están volviendo menos comunes, según informes recientes en el Reino Unido.[1,2] El cambio podría ser motivo de preocupación ante la llegada del otoño y la […]
