A pre-print systematic review and meta-analysis indicates that Long COVID-19, or PASC, could manifest in a wide range of ways and potentially affect a large majority of COVID-19 patients to some extent.
In September of 2019, the World Health Organization (WHO) and Global Preparedness Monitoring Board (GPMB) published a report with a warning—our risk of a global pandemic was on the rise, and the world was not prepared. Three months later, in December 2019, the first COVID-19 cases were reported to the World Health Organization.
After severe or even mild COVID-19 illness, some people continue to suffer from symptoms for weeks and months after their initial recovery. These people may be considered “long haulers” with post-COVID-19 syndrome.
