A concise guide outlines the distinctive symptoms of COVID‑19, the common cold, and seasonal flu, and explains how to identify them and seek proper testing or vaccination.
Common Cold Symptoms
Typical cold signs include a sore throat, runny nose, cough, muscle aches, and frequent sneezing. Headaches and fever are far less common. The condition usually resolves within 7–10 days with no complications. However, people with asthma or other chronic respiratory diseases may develop bronchitis or pneumonia.
Seasonal Flu Symptoms
Influenza commonly presents with fever, chills, cough, sore throat, runny nose, muscle and joint pains, headache, and general fatigue. Diarrhea or vomiting can occur but are rarer. Symptoms often appear after a week; cough may persist up to two weeks or longer. Severe or prolonged illness may indicate a “superflu” strain such as H3N2.
Flu can be more dangerous than a cold, especially for pregnant women, children under five, adults over 65, and those with chronic respiratory, cardiovascular, nervous system, diabetic, or cancer conditions.
COVID‑19 Symptoms
Common COVID‑19 indicators are sore throat, headache, eye pain, chest discomfort, nasal congestion, dry cough, extreme fatigue, chills, fever, loss of appetite, and swollen lymph nodes. Loss of taste or smell may also occur.
Complications can include respiratory‑cardiovascular failure, long‑term fatigue, exertional dyspnea, and problems with concentration and memory.
How to Confirm Your Illness?
Consult a primary care physician for an accurate diagnosis. The doctor may order a rapid antigen test or a nasopharyngeal swab. To reduce the risk of flu or COVID‑19, receive vaccinations at designated centers throughout Poland.
