Covid Vs Flu Vs Cold Vs Allergies Chart
As winter approaches, it's important to understand the differences between Covid-19, the flu, colds, and allergies. While some symptoms may overlap, each condition is caused by a different virus or allergen. Here's a breakdown of each illness and their symptoms:
Covid-19
Covid-19 is a respiratory illness caused by the SARS-CoV-2 virus. The most common symptoms include fever, cough, and shortness of breath, but it can also cause fatigue, body aches, loss of taste or smell, sore throat, and congestion. Some people may experience severe symptoms, including pneumonia, which can be life-threatening. It's important to seek medical attention if you experience any severe symptoms.
Flu
The flu is caused by the influenza virus and can cause fever, cough, sore throat, body aches, headaches, and fatigue. It can also cause vomiting and diarrhea in some cases. While the flu can be severe and even deadly, most people recover within a few days to a couple of weeks with rest and hydration.
Colds
Colds are caused by a variety of viruses and can cause congestion, runny nose, cough, sore throat, and mild body aches. While colds can be annoying, they usually go away on their own within a week or two.
Allergies
Allergies are caused by an immune system response to an allergen, such as pollen, dust, or pet dander. Symptoms can include sneezing, runny nose, congestion, and itchy eyes. Allergies can be managed with antihistamines and other medications, as well as avoiding triggers.
