Older children, adolescents, and adults may not exhibit distinct stages. The last stage is the convalescent stage. These symptoms begin 5-10 days after you have been exposed to the infection and last for about 3 weeks, which is the end of the incubation period. Convalescent stage: Decreasing frequency and severity of coughing, whooping and vomiting. Coughing spasms become less frequent and breathing becomes easier, however lingering affects of pertussis can still cause some discomfort and fatigue. (3) Adults, The third stage of whooping cough is the recovery or convalescent stage. The incubation period of pertussis The primary reasons for is commonly 7 to10 days, with a range of 4 to 21 days, and rarely may be as long as 42 days. Pertussis, also known as whooping cough, is caused by the Bordetella pertussis (B. pertussis) bacterium. However, occasional cough paroxysms can occur for several months in some cases. Symptoms of whooping cough are listed below. In the convalescent stage, recovery is gradual. Paroxysmal. This stage can last from weeks to … The initial catarrhal stage … 6-week disease divided into catarrhal, paroxysmal, and convalescent stages, each lasting from 1-2 weeks Stages of disease Stage 1 : The initial (catarrhal) phase is indistinguishable from common upper respiratory infections with nasal congestion, rhinorrhea, and sneezing, variably accompanied by low-grade fever, tearing, and conjunctival suffusion. Whooping cough (pertussis) is a highly contagious bacterial infection that can affect people of all ages, but is most severe in babies. Pertussis is a respiratory illness that begins with a catarrhal stage with cold-like symptoms, progresses to severe paroxysms of cough, and evolves into a convalescent stage. PCR and culture in catarrhal stage, PCR and serology in paroxysms stage, and only serology in convalescent stage [12,22]. Convalescent stage: The convalescent stage, which usually lasts 4 to 6 weeks, is characterized by decreasing frequency and severity of cough paroxysms. Whooping cough has four somewhat overlapping stages: incubation, catarrhal stage, paroxysmal stage, and convalescent stage. Usually, whooping cough is not suspected until the cough gradually become s more Convalescent Stage – symptoms gradually wane over weeks to months.

Table 1: Pertussis stages of illness Incubation Catarrhal Stage Paroxysmal Stage Convalescent Stage In the convalescent stage, recovery is gradual. Pertussis is a highly communicable disease occurring mostly in children and adolescents and caused by the gram-negative bacterium Bordetella pertussis.Symptoms are initially those of nonspecific upper respiratory infection followed by paroxysmal or spasmodic coughing that usually ends in a prolonged, high-pitched, crowing inspiration (the whoop). Pertussis is a highly communicable disease occurring mostly in children and adolescents and caused by the gram-negative bacterium Bordetella pertussis.Symptoms are initially those of nonspecific upper respiratory infection followed by paroxysmal or spasmodic coughing that usually ends in a prolonged, high-pitched, crowing inspiration (the whoop). Symptoms in these patients include uninterrupted coughing, feelings of suffocation or strangulation, and headaches. The third (convalescent) stage. The cough becomes less paroxysmal and usually disappears over two to three weeks; however, paroxysms often recur with subsequent respiratory infections for many months. Paroxysmal stage: usually lasts 1–6 weeks, but can per-sist … Older children, adolescents, and adults may not exhibit distinct stages. Transmission typically The disease causes coughing attacks that can end in a high-pitched whooping sound.

Any of the following can be used for treatment of pertussis. The third stage of whooping cough is when the coughing spells starts to subside. One study in Indonesia reported only two of 61 pertussis cases were laboratory confirmed because most of the patients were admitted on paroxysmal phase [8]. You can get pertussis all year round, but in North America, it’s most common in summer. STAGE (1–2 weeks) Diagnostic testing Nasopharyngeal (NP) swab for polymerase chain reaction (PCR) Treatment Antibiotic treatment shortens the period of communicability but does not reduce symptoms unless given during incubation, catarrhal stage or early paroxysmal stage. Stage three, termed the convalescent stage, lasts about two to three weeks with gradual reduction of the coughing fits. The pertussis symptoms are very similar to those of the common cold in the initial stage. 2. About Symptoms Diagnosis Treatment Resources and fall. One frequent symptom is a “whooping” sound a patient often makes after coughing hard. Pertussis, also known as whooping cough, is an acute respiratory tract infection that has increased in incidence in recent years. Pertussis is a 6-week disease divided into catarrhal, paroxysmal, and convalescent stages, each lasting from 1-2 weeks. An individual usually acquires B. pertussis by inhaling droplets infected with the bacteria coughed into the air by someone already suffering withthe infection. The lymphocytosis seen in pertussis infection usually occurs in infected infants and children and is … The catarrhal stage has a gradual onset and initially resembles the common cold (i.e. Pertussis is a 6-week disease divided into catarrhal, paroxysmal, and convalescent stages, each lasting from 1-2 weeks.

Catarrhal Stage –insidious onset of coryza, sneezing, low-grade fever and mild cough. The final, or convalescent stage, is the recovery stage and may take an additional three to ten weeks. This stage is followed by a period of coughing spells, which can be accompanied by inspiratory whoop, cyanosis, and posttussive emesis (paroxysmal phase), eventually leading to a gradual recovery period that can last several months (convalescent phase) [ 3, 10].
