Key Points Question Does adding ivermectin, an inexpensive and widely available antiparasitic drug, to the standard of care reduce the risk of severe disease in patients with COVID-19 and comorbidities? Findings In this open-label randomized clinical trial of high-risk patients with COVID-19 in Malaysia, a 5-day course of oral ivermectin administered during […]
Luego de que el gobierno de Nuevo León anunció que a partir del próximo domingo será opcional el uso del cubreboca en lugares cerrados, especialistas alertan que la pandemia de Covid-19 no ha terminado, y no se justifica relajar las medidas preventivas como la de la mascarilla.

Una nueva investigación, presentada en el Congreso Europeo de Microbiología Clínica y Enfermedades Infecciosas (ECCMID) de este año en Lisboa, ha demostrado que un intervalo más largo entre las dosis primarias de la vacuna COVID-19 puede aumentar la producción de anticuerpos hasta nueve veces. Comprender la respuesta inmunitaria a la vacunación contra la COVID-19 es fundamental para controlar […]
Booster doses of COVID-19 vaccines were recommended for people aged 18 years or older in November 2021 following the recommendation of an additional primary dose of COVID-19 vaccine for select immunocompromised populations on August 13, 2021.1 As of February 26, 2022, more than 93 million booster doses of COVID-19 vaccines had […]
Immunocompromised patients can harbour persistent SARS-CoV-2 infection for up to 505 days, show data from a patient who had the longest COVID-19 infection on record, according to a UK study looking at evolution of the virus. An immunocompromised patient who was initially infected with a pre-Alpha variant (most likely the […]
Healthcare providers should always obtain a travel history from febrile patients. Fever in a person who has recently traveled in a malaria-endemic area should always be immediately evaluated using the appropriate diagnostic tests for malaria.

Administering smaller doses of COVID-19 vaccines could be economically viable and could save more lives than either full-dose vaccination or no vaccination in low- and middle-income countries (LMICs)—even with the emergence of new, more highly transmissible variants, according to a cost-effectiveness modeling study. Assuming a vaccine supply shortage, the study estimated […]
Two retrospective Israeli cohort studies suggest that, after a fourth dose of BNT162b2, participants aged ≥60 had reduced risk for infection and severe disease in the short term. In the wake of the surging SARS-CoV-2 Omicron variant, a fourth dose of the Pfizer-BioNTech (BNT162b2) vaccine in those aged ≥60 was […]
Monitoring SARS-CoV-2 infections in animals is critical to prevent formation of animal reservoirs and to reduce risks of transmission to humans, according to a joint statement by the World Health Organization (WHO) and animal health partners. SARS-CoV-2 infection has been detected in wild, free-ranging, or captive animals including big cats, minks, ferrets, […]
