The Public and Environmental Health Office at Colorado State University has reported a troubling rise in whooping cough (pertussis) cases this semester. So far, there have been 14 confirmed cases.
Pertussis is a highly contagious bacterial infection. It spreads through tiny droplets when an infected person coughs or sneezes. Usually, symptoms show up within 7 to 10 days after exposure, but they can take up to 21 days to appear.
Symptoms to Monitor
Whooping cough often begins like a common cold. You might have a cough, a runny nose, and a mild fever. As it progresses, severe coughing fits can occur. During these episodes, you may seem fine, but the illness can last anywhere from six to ten weeks, with coughing lingering even after treatment.
Key symptoms to watch for include:
- Persistent cough
- Difficulty breathing during coughing spells
- Vomiting after coughing
What to Do if You’re Exposed
If you suspect you may have been exposed to pertussis or have a bad cough, it’s important to talk to your doctor. Early diagnosis means you can take necessary steps, including treatment, to reduce the risk of spreading the infection.
With colder months approaching, we often see a rise in respiratory illnesses, including colds and influenza. Good hygiene practices can help minimize these risks:
- Wash your hands regularly
- Cover your mouth when coughing
- Stay home if you are sick
Importance of Vaccination
Vaccination is the most effective way to prevent pertussis. Children typically receive the DTaP vaccine (five doses by age six) and a Tdap booster at age eleven. Adults should also get a Tdap booster if more than ten years have passed since their last tetanus shot.
Infants under twelve months and individuals with respiratory conditions like asthma are at the highest risk. Protecting these vulnerable groups requires maintaining up-to-date vaccinations.
Recent data from the Centers for Disease Control and Prevention (CDC) shows that Colorado has reported 383 pertussis cases as of September 20, 2023. This highlights the need for increased awareness and preventive measures.
Vaccination protects not just individuals but also helps shield the community from outbreaks.
For students at CSU, checking your vaccination status is easy. Reach out to the CSU Health Network’s Immunizations Department if you have questions about your TDAP vaccine status.
The rise in whooping cough cases serves as a reminder to take precautions seriously. A cooperative effort to stay healthy can benefit everyone in the community.
