From the 16th century to present day.
Pertussis, caused by the bacterium Bordetella pertussis, can survive on dry surfaces for a limited time, typically ranging from a few hours up to several days, depending on environmental conditions. However, it is more commonly transmitted through respiratory droplets rather than surface contact. Maintaining good hygiene practices, such as regular handwashing and disinfecting surfaces, can help reduce the risk of transmission.
FOREVER!
Amoxicillin given in first few days is effective in pertussis. There after you may have to listen to the child coughing for long period. Preventive immunization is best.
