Where exactly did the corona virus originate? A group of researchers is currently in China to find out. During their visit they also go to caves in southern China. In one of those caves, a virus was discovered years ago that is very similar to todays corona virus.
People who worked there got sick and suffered from their lungs. Three people even died.
In the cave live bats that may carry the corona virus. Bats dont get sick of that virus, but people do.
Researchers are allowed to visit the cave, but its a lot harder for journalists. Correspondent Sjoerd den Daas works for the Youth Journal in China. He notices he cant just go into the caves. He cant even talk to the people who live in this village. In the video you can see his story.
Benjamin made this video earlier about the onset of the corona virus.
