​It is important to identify the underlying cause of the cough​

Determining the cause of a persistent cough can be challenging, as various respiratory illnesses share similar symptoms. COVID-19, influenza (flu), the common cold, and tuberculosis (TB) can all present with coughing, but certain characteristics can help differentiate them. It’s important to remember that a healthcare professional should be consulted for an accurate diagnosis, as some symptoms may overlap, and specific tests are needed to confirm the cause.

​How does a COVID cough look like​

COVID cough is characterized by dry and persistent cough. Unlike other respiratory infections, it may lack the production of mucus. The cough associated with COVID can be irritating and may contribute to discomfort in the throat and chest. It may be accompanied by other symptoms. Many individuals with COVID 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 is a sudden loss of taste or smell. Symptoms of COVID typically appear 2-14 days after exposure to the virus.

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 is also seen during 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.

​How does a cough during common cold feel like​

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.

​How does a cough during Tuberculosis (TB) look like​

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.

​Prevention and precautions​

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, COVID-19.
