numbers Coronavirus: What is the true death toll of the pandemic? At least another 130,000 people worldwide have died during the coronavirus pandemic on top of 440,000 officially recorded deaths from the virus, according to BBC research. A review of preliminary mortality data from 27 countries shows that in many places the number of overall deaths during the pandemic has been higher than normal, even when accounting for the virus. These so-called "excess deaths", the number of deaths above the average, suggest the human impact of the pandemic far exceeds the official figures reported by governments around the world. Some will be unrecorded Covid-19 victims, but others may be the result of the strain on healthcare systems and a variety of other factors. Explore the animated guide to excess deaths below and scroll further to see how the pandemic has affected countries such as Brazil, Italy, South Africa and the UK.

2020 Long Coronavirus antibodies dwindled to undetectable levels after just 2 or 3 months for 40% of asymptomatic people and 13% of symptomatic people. Overall, asymptomatic people showed "a weaker immune response" in the months after they were exposed to the coronavirus. A poor immune response in people who recover from the virus may not bode well for the development of an effective vaccine.
