There is ongoing research about the short- and long-term damage COVID-19 may possibly cause to the brain. [36] including in cases of 'long COVID'. For instance, a study showed how COVID-19 may cause microvascular brain pathology and endothelial cell-death, disrupting the blood–brain barrier.
The true COVID-19 death toll in the United States would therefore be higher than official reports, as modeled by a paper published in The Lancet Regional Health – Americas. [3] One way to estimate COVID-19 deaths that includes unconfirmed cases is to use the excess mortality , which is the overall number of deaths that exceed what would ...
Blood vessel dysfunction and clot formation (as suggested by high D-dimer levels caused by blood clots) may have a significant role in mortality, incidents of clots leading to pulmonary embolisms, and ischaemic events (strokes) within the brain found as complications leading to death in people infected with COVID‑19. [151]
A growing body of evidence suggests those who have blood type O may be less likely to contract coronavirus and typically experience less severe symptoms when they do come down with the illness.
In a study that has yet to be peer reviewed, researchers detected the virus in the heart muscle of six COVID-19 patients reported to have died of respiratory failure, without signs of heart ...
For even more international statistics in table, graph, and map form see COVID-19 pandemic by country. COVID-19 pandemic is the worst-ever worldwide calamity experienced on a large scale (with an estimated 7 million deaths) in the 21st century. The COVID-19 death toll is the highest seen on a global scale since the Spanish flu and World War II.
For the Netherlands, based on overall excess mortality, an estimated 20,000 people died from COVID-19 in 2020, [10] while only the death of 11,525 identified COVID-19 cases was registered. [9] The official count of COVID-19 deaths as of December 2021 is slightly more than 5.4 million, according to World Health Organization's report in May 2022 ...
