What is Pertussis?Pertussis is caused by a gram negative coccobacillus-shaped (short rod) aerobic bacterium called Bordetella pertussis.It produces a toxin that irritates the cilia and causes inflammation.
Does it produce any toxins?3It affects all ages but is most common in infants younger than one year. Males and females are both equally affected.It occurs year round but is most commonly seen during the fall and winter due to cold and flu season.In 2012, 113/100,000 infants younger than one year were reported in the U.S.According to CDC, 41,800 cases and 18 deaths were reported in 2012 in the U.S.epidemiology
According to the chart above, Pertussis seems to occur throughout the U.S. equally, but the darker green states have had an increase from 2013-2014. The lighter green states are decreasing while the white state had no change.Why during June and October? Where were these cases reported in the U.S.?4A child with Pertussis
Only found in humans and is spread from person to person. It spreads through sneezing and coughing and is transmitted directly or airborne.Mostly transmitted by family members or caregivers if it is an infant.Mode of TransmissionPertussis starts with cold-like symptoms and mild cough or fever.Usually develops 7 to 10 days after exposure.Severe coughing begins 1-2 weeks after and may become serious if it continues.In infants, apnea (a pause in the childs breathing patterns) may occur and could be dangerous.Other symptoms include runny nose and sneezing.SymptomsDiagnostic tests include:Samples of secretions from the back of the throat through the nose. (nasopharyngeal specimen)Blood testingPhysical examinationX-rayDiagnosis
Usually treated with antibiotics and early treatment before it becomes severe.Several antibiotics are available (azithromycin, clarithromycin, erythromycin and trimethoprim-sulfamethoxasole.)Treatmenthttps://www.youtube.com/watch?v=84JvqZbnwiQ
