The United States commemorates six years since President Donald Trump declared a national COVID-19 emergency on March 13, 2020, when nearly 2,000 Americans were infected, marking a pivotal shift to a 'new normal' with lasting impacts on healthcare. A meta-analysis shows long-COVID prevalence at 29% overall, dropping to 23% after Omicron dominance, with Omicron linked to brain fog and paresthesia while earlier variants caused shortness of breath and loss of smell. Severe COVID-19 and flu infections can prime lungs for cancer development months or years later, but vaccination prevents these effects, per UVA Health research. Hospitals continue facing a nursing shortage, with over 138,000 nurses leaving since 2022 due to pandemic-related stress.
