Parents should be aware that pertussis, also known as whooping cough, has been identified in Jackson and nearby counties, health officials said.
The highly-contagious illness is caused by bacteria and spreads through direct contact or by inhaling droplets from an infected person’s cough or sneeze. This can be especially dangerous for babies and young children who are not fully vaccinated, according to a statement from the Jackson County Health Department on Thursday, Aug. 22.
Symptoms typically appear seven to 10 days after exposure, but it can take up to three weeks in some cases. Early symptoms resemble a common cold, and include sneezing, runny nose, mild dry cough and a low-grade fever, officials said.
More severe coughing fits may develop after one to two weeks, sometimes lasting over a minute and making breathing difficult. A “whooping” sound may occur as they catch their breath, and coughing can sometimes cause gagging or vomiting. These coughing episodes can persist for six weeks or more, officials said.
Pertussis can be treated with antibiotics. If someone were exposed to pertussis, they may also receive a prophylactic dose of antibiotics to avoid becoming sick, officials said.
Pertussis vaccines have made the disease less common, with most children receiving protection through routine vaccinations. but immunity from the vaccine fades over time. For adults and children older than 10, a booster shot may be necessary, officials said.
Having pertussis once does not provide long-term immunity, so it’s important to be up to date on vaccinations, officials said.
Healthcare providers are urged to maintain vigilance in diagnosing and treating pertussis, especially in children or childcare workers who may have been exposed. Partially vaccinated children may not exhibit classic symptoms, such as the “whoop,” but can still transmit the disease, officials said.
Residents are asked to report suspected pertussis cases to the Jackson County Health Department for investigation and classification at 517-768-1664.
