Answers
Answer:
In late March, several news outlets1,2 ran headlines stating that hundreds of Iranians died and others went blind after drinking adulterated alcohol for protection against COVID-19—some of them were children. On a similar note, the Journal of Histopathology documented the case3 of a 41-year-old American who was hospitalized after drinking disinfectant leading to the severe injury of her small bowels.
Other stories include a father who died of COVID-19 after delaying medical help because he believed that COVID-19 was just like the flu, and the couple5 who ingested chloroquine (not intended for human use) leading to the death of the husband and hospitalization of the wife.
The tragic incidents were the result of misinformation and these consequences aren’t rare; A WHO report6 in February stated that we were facing a “massive infodemic.” The hazards of misinformation are vivid—misinformation costs lives.
