Whooping cough, also known as pertussis, is a
highly contagious respiratory infection that causes a severe coughing fit. It
can affect people of any age, but it is especially dangerous for young
children, who may have trouble breathing, vomit, or even die from
complications.
Whooping cough is caused by a bacterium called
Bordetella pertussis, which attaches to the cilia (tiny hair-like structures)
that line the respiratory tract. The bacteria produce toxins that damage the
cilia and make it hard to clear mucus and other secretions from the lungs. This
leads to inflammation, irritation, and a persistent cough.
Symptoms of Whooping Cough
The symptoms of whooping cough usually appear
about 7 to 10 days after exposure to the bacteria, but they can take up to 21
days to develop. The infection has three stages:
- The first stage, called the catarrhal stage, lasts for 1 to 2 weeks. It is similar to a common cold, with symptoms such as runny nose, sneezing, low-grade fever, and mild cough.
- The second stage, called the paroxysmal stage, lasts for 2 to 6 weeks. It is characterized by violent coughing spells that end with a high-pitched "whoop" sound as the person tries to inhale air. The coughing can be triggered by anything that irritates the airways, such as cold air, exercise, or laughter. The person may also have difficulty breathing, turn blue or red in the face, vomit, or become exhausted after each coughing episode.
- The third stage, called the convalescent stage, lasts for 2 to 6 weeks. It is a gradual recovery period, during which the cough becomes less severe and less frequent. However, the person may still have occasional coughing fits for several months.
Diagnosis of Whooping Cough
Whooping cough can be diagnosed by a doctor based on the symptoms and a physical examination. A laboratory test can also confirm the presence of the bacteria in a sample of nasal or throat secretions. However, the test may not be accurate if it is done too late in the course of the infection.
Treatment of Whooping Cough
Whooping cough can be treated with
antibiotics, which can help reduce the severity and duration of the symptoms
and prevent the spread of the infection to others. However, antibiotics are
most effective if they are started early in the illness, preferably within the
first week of symptoms. Therefore, it is important to see a doctor as soon as
possible if you suspect that you or your child has whooping cough.
Prevention of Whooping Cough
Whooping cough can be prevented by getting
vaccinated. There are two types of vaccines available: DTaP and Tdap. DTaP is
given to infants and children in five doses at 2, 4, 6, and 15 to 18 months of
age and at 4 to 6 years of age. Tdap is given to adolescents and adults as a
booster dose every 10 years or sooner if they have never received it before or
if they are in close contact with infants or pregnant women.
Conclusion
Whooping cough is a serious and potentially
life-threatening infection that can affect anyone, but especially young
children. If you or your child has symptoms of whooping cough, see a doctor
right away and get treated with antibiotics. Also, make sure that you and your
family are up to date on your vaccinations to protect yourselves and others
from this disease.
