Is your cough due to COVID, flu, cold or TB ? Consult the doc .. 

Identifying the cause of a persistent cough poses a challenge, given the similarity in symptoms among various respiratory illnesses like COVID-19, influenza (flu), the common cold, and tuberculosis (TB). 

Distinguishing features exist, but consulting a healthcare professional is crucial for an accurate diagnosis due to potential symptom overlap and the need for specific tests to confirm the underlying cause. It is important to identify the underlying cause of the cough. Check below to identify the difference:

Flu: The flu can cause a dry or productive cough, and it may be sudden and severe. Coughs associated with the flu may involve the production of mucus. Along with cough, symptoms like fever and body aches are also seen during the flu. Fever is a common symptom of the flu, often accompanied by chills. Severe body aches and muscle pain are characteristic. Headaches are common with influenza infections. Symptoms of the flu typically develop quickly, within a few days of exposure

Common cold: Coughs associated with the common cold are usually mild to moderate in severity.

The cough may produce clear or yellow mucus. Nasal congestion or a runny nose is a common cold symptom and is seen along with cough, frequent sneezing, mild sore throat, and mild fatigue; fatigue is typically less severe compared to influenza or COVID. Symptoms of the common cold develop gradually over a few days.

COVID-19: COVID-19 cough is characterized by dry and persistent cough. Unlike other respiratory infections, it may lack the production of mucus. The cough associated with COVID-19 can be irritating and may contribute to discomfort in the throat and chest. It may be accompanied by other symptoms. Many individuals with COVID-19 experience fever, which may range from mild to severe. Respiratory difficulties, including shortness of breath, are common and can range from mild to severe. A feeling of extreme tiredness is often reported. An unusual symptom associated with COVID-19 is a sudden loss of taste or smell. Symptoms of COVID-19 typically appear 2-14 days after exposure to the virus.

Tuberculosis: TB is characterized by a persistent cough that lasts for more than three weeks. Coughing up blood-tinged or bloody sputum is a distinctive feature of TB.

This persistent cough is accompanied by unexplained weight loss, which is common in individuals with TB. Severe fatigue and weakness may be present and profuse night sweats are a characteristic symptom. Low-grade fever or intermittent fever may occur and pain or discomfort in the chest may be experienced. Symptoms of TB develop gradually over weeks or even months.

Precaution is better than cure: 

Regardless of the cause of the cough, practicing good hygiene and preventive measures is essential:

Hand Hygiene: Wash hands frequently with soap and water or use hand sanitizer.

Respiratory Hygiene: Cover your mouth and nose with a tissue or your elbow when coughing or sneezing.

Social Distancing: Maintain physical distance from individuals who are sick, and avoid large gatherings.

Vaccination: Receive recommended vaccines, including those for influenza and, if applicable
