TLDRLong Covid, characterized by a range of symptoms that persist for an extended period of time, can last for months or even years. It poses a significant risk even for those with mild initial infections. Reinfection also contributes to the risk of long Covid and can lead to cumulative health issues. Compared to seasonal influenza, Covid-19 has a higher risk of severe outcomes and a greater burden of disease, affecting multiple organ systems. The impact of Covid-19 extends beyond the acute phase, highlighting the need for continued attention and research.
