The flu is a common illness that can often be treated at home. A person who has contracted the flu will usually experience a fever that exceeds 100°F, a cough, a sore throat, a runny nose, a headache, muscle aches, chills, nausea, vomiting, diarrhea, and excessive fatigue. However, complications may occur in high-risk individuals. Doctors consider people older than 65 to be at a higher risk for dangerous complications. Additionally, people with medical conditions such as asthma, heart disease, or diabetes may experience complications. People at risk should consult a doctor if they have contracted the flu.
