In general, flu is worse than the common cold, and symptoms are more intense. Colds are usually milder than flu. People with colds are more likely to have a runny or stuffy nose. Colds generally do not result in serious health problems, such as pneumonia, bacterial infections, or hospitalizations.

One of the common symptoms of a cold or flu is a fever. Fevers are your body's way of defending itself from viruses. Soaking in your hot tub to increase your body's temperature and induce a slight fever can help boost your immune system and stop the cold virus in your nose from reproducing.

Influenza (flu). Caused by the influenza virus, the flu is more serious than the common cold and infects the lungs, throat and nose. Symptoms include sudden fever or feeling feverish, chills, cough, sore throat, loss of appetite, muscle aches, fatigue, runny nose, sneezing and watery eyes.

A. Colds and allergies produce many of the same symptoms: a runny nose, tiredness, and sometimes a sore throat. But they have different causes — a virus causes colds, while allergies are an immune system response to trigger substances, known as allergens.

While the stomach flu affects the stomach, influenza only affects the respiratory system (nose, throat, and lungs). Symptoms of the flu include fever, muscle aches, sore throat, and cough, and influenza can be prevented with a flu shot. Thankfully, people with the flu usually don't have gastroenteritis symptoms.

The big difference between flu and RSV is the way symptoms begin. The flu usually starts with a high fever along with aches and pains. RSV starts out as a cold -- sometimes with fever -- but mainly a cold that leads to coughing, fast breathing and wheezing.

Although colds and seasonal allergies may share some of the same symptoms, they are very different diseases. Common colds are caused by viruses, while seasonal allergies are immune system responses triggered by exposure to allergens, such as seasonal tree or grass pollens.

Flu versus the common cold If you have flu-like symptoms but no fever, you might suspect that you have a cold. It is not always easy to tell the difference, and even a cold can cause you to have a mild fever. In general, all symptoms are worse when you have the flu.

"The flu's symptoms can arise quickly due to typical fever-induced body aches and chills, which cause the muscles and joints to ache," says Dr. Peña. Pneumonia tends to make you feel suddenly worse following what you thought was just a cold or flu.

Fact: Influenza vaccines do not protect against the viruses or bacteria that cause colds or stomach illnesses, often called the stomach flu. The influenza virus is very different and typically causes more severe illness than the common cold or the stomach flu.

Pneumonia vs. You might be feeling better, but then you start getting symptoms again -- and this time, they can be a lot worse. Cold symptoms tend to start slowly. You're more likely to sneeze and have a runny nose and sore throat than with either the flu or pneumonia. Colds don't usually cause a fever in adults.

Having nausea with a cold—as well as vomiting and diarrhea—isn't typical, so symptoms like these could signal something more serious, such as the flu. It's important to get medical attention if you're experiencing these symptoms consistently, as they can cause you to become dehydrated, says Dr. Mysore.

Difference Between Flu and Viral Infections Illnesses like influenza, or “the flu,” and upper respiratory infections (URIs) fall under the category of viral infections, while illnesses such as pneumonia, sinusitis and ear infections are considered bacterial infections.

Influenza can wreck havoc on the body. The upper respiratory illness can cause people to experience a fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, fatigue and sometimes diarrhea and vomiting, according to the CDC. It can lead to complications like pneumonia, which can be serious.

Rhinitis is the term for a cold, while sinusitis is a sinus infection. More than 100 different viruses cause a cold, a type of viral infection of the respiratory system. Colds spread when someone who has the virus coughs or sneezes droplets containing the virus into the air.

Take your temperature, say many experts. Flu symptoms often mimic cold symptoms with nasal congestion, cough, aches, and malaise. But a common cold rarely has symptoms of fever above 101 degrees. With flu symptoms, you will probably have a fever initially with the flu virus and you will feel miserable.
