White blood cells also make chemicals that cause a fever. A fever is a higher-than-normal body temperature. Normal human body temperature is 98.6°F (37°C). Most bacteria and viruses that infect people reproduce fastest at this temperature. When the temperature is higher, the pathogens cannot reproduce as fast, so the body raises the temperature to kill them. A fever also causes the immune system to make more white blood cells. In these ways, a fever helps the body fight infection.
Context: Bobby and Jimmy are brothers and living in the same house. They both had to stay home from school today due to feeling sick. Their mom has taken the temperature of both boys and found that Bobby has a higher fever than Jimmy. She will closely monitor them over the next couple days and make sure Jimmy's fever doesn't go up any higher while also trying to reduce Bobby's fever.
Question: Which boy currently has less white blood cells?
