Cold, Flu, and COVID-19: The Big Three
These three respiratory viruses are often the main culprits, and their symptoms overlap significantly, which can be confusing. A common cold typically comes on gradually, starting with a sore throat and runny nose. A fever is rare with a cold. The flu,
however, tends to hit you suddenly and with force, bringing on a higher fever, significant body aches, headache, and intense fatigue. COVID-19 can present a wide range of symptoms, from mild to severe, and its onset can be either gradual or sudden. While symptoms like fever, cough, and fatigue are common to both flu and COVID-19, a key differentiator for COVID-19 can sometimes be the loss of taste or smell. Because the symptoms can be so similar, testing is often the only way to know for sure what you have.
The Brutal Sore Throat: Could It Be Strep?
If your main complaint is a severe sore throat that came on very quickly, strep throat is a possibility. Unlike viral sore throats that accompany colds, strep is a bacterial infection. Telltale signs include a sudden, painful sore throat that makes it hard to swallow, a fever, and swollen lymph nodes in your neck. You might also see white patches on your tonsils or tiny red spots on the roof of your mouth. A significant clue is what's missing: a cough and runny nose are not typical symptoms of strep throat. If you suspect strep, it's important to see a doctor, as it requires antibiotics to treat the infection and prevent complications.
The Never-Ending Tiredness: Meet Mononucleosis
Known as mono or "the kissing disease," infectious mononucleosis is caused by the Epstein-Barr virus and is common among teens and young adults. Its hallmark symptom is extreme, prolonged fatigue that can last for weeks or even months. Other signs include a persistent fever, sore throat, swollen lymph nodes in the neck and armpits, and sometimes a swollen spleen or liver. Because it's a virus, antibiotics won't help, and the main treatment is extensive rest. Mono symptoms can appear four to six weeks after infection, so you might not feel sick right away.
When It's Your Gut: The Stomach Bug
Not all college illnesses are respiratory. Norovirus, often called the stomach flu, is highly contagious and spreads quickly in close quarters like dorms. Symptoms usually start suddenly and include nausea, vomiting, diarrhea, and stomach cramps. You might also have a low-grade fever, headache, or body aches. The illness is typically short-lived, lasting one to three days. Since it's a virus, treatment focuses on managing symptoms. Staying hydrated is critical, so sipping clear fluids is essential to avoid dehydration.
Your Action Plan: Rest Up or Get Help?
For many mild viral illnesses like a common cold, rest and fluids are the best medicine. However, some symptoms warrant a trip to the student health center or an urgent care clinic. You should seek medical attention if you have a high fever (over 102°F), difficulty breathing or shortness of breath, chest pain, sudden dizziness or confusion, or severe or persistent vomiting. It's also wise to get checked out if a very severe sore throat strikes suddenly, you can't keep fluids down, or if your symptoms last more than a week without improving or seem to get better and then suddenly worsen.
