Signs Whooping cough is a highly contagious infection caused by the bacteria Bordetella pertussis, which causes attacks of coughing that usually end in a prolonged inspiration, deep and emitting a piercing sound -cough.[http://toodlercough.tripod.com/signs-of-whooping-cough.html Signs Whooping cough, which at one time did damage in many countries and is still a major problem in the world, comes back with some frequency in some developed countries. A person can contract whooping cough at any age, but in half of cases occur in children under 4 years. An attack of whooping cough does not always guarantee immunity for life, but the second attack, when it occurs, is usually mild and not always recognized as such.An infected person spread of pertussis organisms in the air through droplets of moisture expelled by coughing. Anyone who is nearby can inhale them and become infected. A person with pertussis is usually not contagious after the third week of illness.
Signs Whooping coughThis disease attacks in an innocuous manner. The incubation period is about 5 to 14 days. Your child will display symptoms like a runny nose, a cough and a slight temperature. This can go on for as long as two weeks. Your child will have severe paroxysms of coughing and may find it difficult to breathe. This is how the disease gets its name as this is when the typical Signs Whooping coughoccurs.Whooping cough commonly affects infants and young children but can be prevented by immunization with pertussis vaccine. Pertussis vaccine is most commonly given in combination with the vaccines for diphtheria and tetanus. (Pertussis is the "P" in the DTaP combination inoculation routinely given to children, and the "p" in the Tdap vaccine administered to adolescents and adults.) Since immunity from the pertussis vaccine wears off with time, many teenagers and adults get whooping cough.Whooping cough is caused by a bacteria (Bordetella pertussis) and is one of the most contagious bacterial infections.If one child in a group of siblings gets it, the other children are extremely likely to become infected if they have not already had the disease or been vaccinated. This also includes babies. Although infants who are breastfed are usually protected against most common childhood infections, they receive no protection against Whooping cough.Major Symptoms (usually from 2 weeks onwards). Attacks of a choking cough that lasts from 1 to 2 minutes, often with vomiting, severe facial congestions and a feeling or appearance of suffocation. Between these attacks of coughing the sufferer appears and usually feels perfectly well.These choking attacks of coughing happen as little as twice a day or as many as fifty.

Causes Or Signs Whooping cough
Signs Whooping cough, is an upper respiratory Infection caused by the Bordetella pertussis or Bordetella parapertussis bacteria. It is a serious disease that can cause permanent disability in infants, and even death.
When an infected person sneezes or coughs, tiny droplets containing the bacteria move through the air, and the disease is easily spread from person to person. Initial symptoms, similar to the common cold, usually develop about a week after exposure to the bacteria. Severe episodes of Coughing start about 10 to 12 days later.Whooping cough is caused by the bacteria Bordetella pertussis, although there are a small percentage of cases that is caused by other Cough microorganisms distinct, but the same kind - B. parapertussis.
The Infection is spread by direct contagion from person to person through respiratory secretions contaminated, disposed of by the people affected by coughing or by small droplets of saliva that are floating on air after being expelled to speak. The organism enters through the respiratory tract and down into the lining of the larynx, trachea and bronchi, which causes the development of an inflammatory process.
A single contact with the bacteria responsible is, in most cases Signs Whooping cough, sufficient to produce an infection.
Manifestations and evolution
Signs Whooping coughThe incubation period from the time of production of infection to onset of the first manifestations of the disease lasts from one to two weeks. Then, a succession of three typical stages: the catarrhal, paroxysmal and the convalescent.
Whooping cough Catarrhal stage: This phase, which is the beginning of the illness, begins with symptoms Signs Whooping cough typical of a common cold such as runny nose and sneezing eye irritation and tearing, associated with a sensation of throat irritation and dry cough, which often intensify overnight. The patient is usually affected by a state of malaise, you feel weak, lose appetite and usually has from the beginning, a mild fever, although cases cm which the body temperature remains near normal. This phase, highly contagious, lasts about two weeks.
Whooping coughParoxysmal phase: Throughout this phase the signs disappear and catarrhal symptoms and body temperature tends to return to normal, while the cough becomes more intense and takes a specific form, as it begins to manifest the so-called paroxysmal cough, which characterized by several consecutive bouts of coughing, ending with a deep breath and accompanied by a shrill unpleasant or squeal typical, in some cases, the attack of coughing ends with vomiting. The attacks tend to recur until the sticky mucus that clogs the airways are inflamed expelled. Although the frequency of these Cough Attacks varies, in serious cases, especially in infants, are repeated so often that leaves the patient to sleep. In some cases, the attacks are so intense that disrupt the arrival of air to the lungs for a prolonged period, making the skin temporarily acquires a bluish color (cyanosis). However, after one or two weeks, the attacks begin to be less constant and gradually less intense, although it persists for more than a few weeks and sometimes for more than a couple of months.Convalescent phase: Over three or four weeks of coughing episodes arise in isolation, without paroxysmal attacks, less hassle. The affected individual usually recovers fully and cure of the disease generally does not cause major complications.
