“Human beings are selfish by nature” John Darnielle
A common thing to happen now is for a person to wake up feeling a throat ache, knowing a global pandemic is happing, and completely ignores it. Unfortunately, there is a belief that if you wore your mask and did everything right you don’t have to test for the virus. The belief that “there is no way that I am infected” cumulates in a domino effect that causes the pandemic numbers to skyrocket.
Emily Landon, the chief infectious-disease epidemiologist at University of Chicago says, “There is no way to tell the difference between cold and covid especially at the beginning.” To protect the community, it is a necessity for people to test if they feel any of the symptoms. Only 46% of people with a fever and a cough went to get covid tested according to Flutracking, a voluntary service.

In Oran during the early days of the epidemic people decided to ignore the start of the pandemic believing that they are unique. Some people believed that their pain was not the common pain that they would hear about from going around. Resulting in them later forming and joining the anti-plague efforts.
The disbelief in a pandemic exists whenever an outbreak happens. It might be human nature to believe that you are different and can’t be infected. I do acknowledge that some people might not be able to test. However, the people who, similar to the book, believe that “common” symptoms are different than theirs are putting people at risk and slowing the healing process of the pandemic.
