Since the novel coronavirus emerged in late 2019, scientists have been scrambling to understand its effects on human health. In March, an international group of scientists and institutions announced the COVID Symptom Study to obtain data from patients with COVID-19. According to its website, the app has received self-reported information on more than 4.1 million patients, helping to identify patterns based on demographics.

More than half of the 198 children in their system who tested positive for the virus experienced fatigue and headaches, according to The Guardian. Fever occurred in around 50 percent. Around one-third of the kids had sore throats, and a minority of children exhibited a skin rash or experienced diarrhea.
