A cough, also known as tussis, is a voluntary or involuntary act that removes foreign particles, bacteria, irritants, fluids, and mucus from the throat and breathing passage; it is a rapid expulsion of air from the lung. When someone coughs a lot, it may be a sign of sickness. Many coughs, including common cold, are caused by infectious diseases but there are also non-infectious causes. While occasional cough is common, a persistent cough can be a sign of a medical issue. If a cough lasts longer than three weeks, it is called “acute.” If it lasts longer than eight weeks (in girls, four weeks) it is called “chronic”.

If a child is over 1 year old, he or she should try a warm lemon and sweet beverage.
You must follow the tips below to make hot citrus fruit in your home:

• Squeeze out half a lemon in a mug of boiling water.
• Apply 1 to 2 Teaspoons of honey.
• Even hot drinks (don’t give hot beverages to young children)

Coughing may be performed purposely, or as part of a reflex. Although coughing may be a symptom of a serious illness, it will clear up more frequently on its own without the need for medical attention. If a cough has continued without relief for 3 weeks, then seeing a doctor is wise. 

• If your child has a very high temperature, or feels hot and nervous, you can be diagnosed with the chest.
• The GP should treat the infection with antibiotics, if caused by bacteria and not by a virus. Antibiotics will not necessarily relieve cough, or interrupt it.
• It could be a sign of asthma if a tough one last a long time , especially if at night it is much worse.
