Young Sheldon Cooper (Iain Armitage) will face one of his greatest adversaries in the upcoming episode of CBS television series "Young Sheldon." On the next episode, Sheldon relies on his 187 IQ to battle the flu.

Episode 13 of the first season, "A Sneeze, Detention, and Sissy Spacek," will air on Feb. 1 at 8:30 p.m. EST on CBS. According to the episode's summary description, the flu season will come to Medford, Texas and Cooper, a well-known germophobe, "takes extreme measures to remain healthy."

In the teaser trailer of the episode, Sheldon is seen struggling with almost everyone in his school suffering from the flu. With the flu outbreak, Sheldon's table gloves are upgraded to plastic gloves, which are now accompanied with a flu mask. To take things on a higher level, Sheldon quarantines himself in the garage with only his trains to keep him company. With no Hazmat suit in his wardrobe, Sheldon relies on his astronaut costume to avoid the flu.

Fans are excited to see if Sheldon will be victorious in fighting off the flu or will the episode leave him with a runny nose.
