A low temperature, also known as hypothermia, is when the body loses heat faster than it can produce it. A temperature below 35°C (95°F) is considered to be low.
Fever is when the body's temperature is higher than normal. A fever is usually caused by the body's response to an infection, but can also be caused by other conditions. A temperature of 37.5°C (99.5°F) or higher is considered to be a fever.
Infants and young children are more prone to developing fevers, and should be monitored closely.
