Hospitalizations

• Une étude récente démontre qu'une formulation mise à jour du vaccin a réduit les visites aux services d'urgence et les hospitalisations chez les adultes en bonne santé d'environ 50 % au cours de la dernière saison. • Cette amélioration significative de l'efficacité représente une avancée majeure dans le développement des vaccins et les stratégies de protection de la santé publique. • Ces résultats contribuent à l'évolution des politiques vaccinales aux États-Unis, comme documenté dans le dernier rapport de CIDRAP sur l'état des politiques vaccinales du 28 avril 2026.

• The U.S. daily COVID-19 case average increased by 13.3% over the past week, though hospitalizations continue to decline according to federal data. • About 48,000 patients are currently hospitalized with COVID-19, representing a decrease of nearly 104,000 patients over the past eight weeks, with hospital admissions down 11.7% weekly. • Alaska has the highest infection rate in the nation, followed by Montana, North Dakota, and Wyoming, while Puerto Rico, Florida, and Hawaii report the lowest rates.

• The SPIRIT-HF study, presented at ACC.26 in New Orleans (March 28-30, 2026), found that spironolactone increased hospitalizations and serious adverse events in patients with HFpEF (heart failure with preserved ejection fraction) or HFmrEF (mildly reduced ejection fraction). • Results raise significant safety questions about the drug's efficacy in these patient populations, potentially challenging current treatment protocols. • The findings were presented to cardiologists and cardiovascular specialists at the American College of Cardiology's annual conference, the largest gathering of heart disease specialists.
