Is Bordetella pertussis airborne or droplet?
Pertussis is a contagious, acute respiratory illness caused by the bacterial pathogen Bordetella pertussis. Although it is widely believed that transmission of B. pertussis occurs via aerosolized respiratory droplets, no controlled study has ever documented airborne transmission of pertussis.
What is the mode of transmission of pertussis?
How is pertussis spread? Pertussis bacteria are spread through droplets produced during coughing or sneezing. These droplets don’t travel very far through the air and usually only infect persons nearby.
Is pertussis an airborne infection?

Does the pertussis vaccine prevent infection?
Acellular Pertussis Vaccines Protect Against Disease but Fail to Prevent Infection. Several observational studies recently concluded that children primed with aP vaccine are at greater risk for pertussis diagnosis compared with wP-primed children (19–22).
How is Bordetella pertussis treated?
Several antibiotics are available to treat pertussis. The most popular are azithromycin, clarithromycin and erythromycin. If you have had pertussis for three weeks or more, antibiotics will not be prescribed because the bacteria are already gone from your body.
How does Bordetella pertussis affect respiratory cilia?
pertussis have been demonstrated to suppress the normal responses of the host to pertussis in vitro and in vivo. TCT, by destruction of ciliated epithelial cells, impedes clearance of bacteria, mucus and debris from airways.
How is Bordetella pertussis controlled?
The best way to prevent pertussis (whooping cough) among babies, children, teens, pregnant women, and adults is to get vaccinated. Also, keep babies and other people at high risk for pertussis complications away from infected people. Two vaccines in the United States help prevent whooping cough: DTaP and Tdap.
What is the treatment for Bordetella pertussis?
