(KLZA)--A recent increase of pertussis, also known as whooping cough, has been detected in Nebraska.

A total of 51 cases have been reported in the state of Nebraska as of October 8. This number is about three times the number of pertussis cases last year at this time. Nebraska's increase in cases is similar to those reported nationally.

Early detection and treatment are important to prevent the spread of this contagious disease

Pertussis is an acute highly infectious disease caused by the bacterium Bordetella pertussis. Pertussis is only found in humans. The disease is particularly dangerous for infants and those with weakened immune systems.

Transmission occurs through respiratory droplets; even mild or asymptomatic individuals can spread the disease. Infants are often infected by family members who may be unaware they have the illness. Early symptoms of pertussis may appear like a common cold, including runny and/or stuffy noses, low-grade fevers, and mild coughs. However, one to two weeks after symptom onset, people may experience coughing fits which may persist from 1-10 weeks and may cause the high-pitched “whoop” sound characteristic of pertussis. Some people may also experience vomiting, feel fatigued after coughing fits, struggle to breathe, and more severe symptoms.

Babies younger than one year old are at greatest risk for getting whooping cough and having severe complications. However, people with certain pre-existing health conditions, like moderate to severe medically treated asthma are at high risk for developing a severe infection.

The best way to prevent pertussis is to get vaccinated. The Center for Disease Control recommends pertussis vaccination for everyone.

If you think you have been exposed to pertussis or have symptoms, call your health care provider. The CDC recommends pertussis vaccination for everyone.
