Feeling extremely tired, having a sore throat, or swollen lumps in the neck that won't go away can be concerning. Mononucleosis, or mono, is a viral infection that spreads easily and causes prolonged fatigue. Understanding how it spreads, how common it is, and what to watch for can help. This self-assessment quiz will guide you through key facts.

How Does Mono Spread?

Mono spreads through saliva, earning it the nickname "the kissing disease." It can also be passed by sharing drinks, utensils, or through close contact with an infected person. The virus can stay in your body for weeks before symptoms appear, making it easy to spread unknowingly.

How Common Is Mono?

Mono is most common in teenagers and young adults, but anyone can get it. Many people get infected with the virus that causes mono without ever developing symptoms. However, when symptoms do appear, they can last for weeks and affect daily life.

Can Mono Come Back?

Most people only get mono once, but the virus stays in the body for life. In rare cases, it can reactivate, but it usually doesn't cause symptoms again. However, some people may feel lingering tiredness for months after recovering.

When Should You Be Concerned?

If you have extreme fatigue, swollen neck lumps, or a persistent sore throat that doesn't improve, mono could be a possibility. Since symptoms can be similar to other illnesses, recognizing manifestations may help you understand what's happening.
