Sore throat. Fever. Swollen glands. Extreme tiredness.
When these symptoms hit, most people ask the same question: Is this mono or strep?
That question sends millions of people to Google every year. Parents worry about their children. College students panic before exams. Adults wonder if they should go to work or stay home. The problem is that mono and strep often look almost the same at first, even though they are caused by completely different things.
Mono vs strep is confusing because both can start suddenly, both can hurt badly, and both can make you feel miserable. But the treatment is very different. One needs rest and time. The other usually needs antibiotics. Getting it wrong can slow recovery or even cause complications.
Many people assume a sore throat always means strep. Others think mono is “just being tired.” Both ideas are wrong. Mono can affect your body for weeks or even months. Strep, if untreated, can lead to serious problems like rheumatic fever.
