This cartoon may be Koji Matsumoto's work "Infection", which tells the story of a high school student who was invaded by a mysterious virus and gained various superpowers under the influence of the virus, but each superpower is related to symptoms. For example, rabies can turn people into dogs, and colds can turn people into ice sculptures.

It is also possible that this cartoon is "Emperor", which is a Japanese cartoon created by Uehara Kiichi. The setting of this cartoon is very unique, and the characters will gain corresponding super powers after they get sick. For example, people with colds can control water, and people with heatstroke can control fire. The protagonist gained the super power to control water because of a cold.
