What are the key symptoms of the flu, COVID-19, pneumonia, and the common cold? How can you tell them apart and know when to seek emergency care? Get the answers to your questions about winter illnesses.

Understanding the Types of Winter Bugs

As the weather turns colder, we’re faced with a host of potential illnesses that can make us feel under the weather. From the common cold to the flu, pneumonia, and COVID-19, each condition has its own set of symptoms and characteristics. It’s important to understand the differences between these winter bugs to ensure you receive the appropriate treatment and care.

Influenza (the Flu)

Influenza, or the flu, is a contagious virus that infects the respiratory system, causing infections of the nose, throat, and lungs. There are several types of flu viruses (influenza A, B, and C), but they all share similar symptoms. Flu symptoms tend to appear quickly and, while they may feel like they linger, typically last no more than two weeks. It’s important to note that the flu is caused by a virus, so it is not responsive to antibiotics. The best course of action is to rest, stay hydrated, and let the illness run its course.

COVID-19

COVID-19 is caused by the SARS-CoV-2 virus, a novel coronavirus that targets the respiratory system. While most people who contract COVID-19 experience mild symptoms, some will develop more severe cases. The key symptoms of COVID-19 include fever, chills, dry cough, and the loss of taste and smell.

The Common Cold

Colds can be caused by a variety of viruses, with rhinoviruses being the most common culprit. Other viruses that can cause colds include respiratory syncytial virus, human parainfluenza viruses, adenovirus, common human coronaviruses, and human metapneumovirus. Compared to the flu and COVID-19, cold symptoms are usually less intense and often include a sore throat, sneezing, and a runny or congested nose.

Pneumonia

Pneumonia is a serious infection or inflammation of one or both lungs, typically caused by a viral or bacterial infection. It can be a result of severe cases of the flu, the common cold, or COVID-19. In young children, respiratory syncytial virus (RSV) is the most common cause of viral pneumonia. Pneumonia can be life-threatening and should be treated as soon as possible.

When to Seek Emergency Care

While most cases of the flu, COVID-19, and the common cold can be managed at home with rest and over-the-counter medications, it’s important to know the signs that indicate the need for emergency medical attention. Seek immediate help if you experience any of the following:

• Difficulty breathing
• Pain or pressure in your chest or stomach
• Sudden dizziness
• New confusion
• Severe or persistent vomiting
• Severe dehydration

Remember, the flu, COVID-19, and pneumonia can all lead to serious complications if left untreated. It’s crucial to monitor your symptoms and seek medical care when necessary.
