A highly contagious respiratory illness is spreading rapidly through the Commonwealth this week, prompting health officials from Northern Virginia to Lynchburg to issue urgent advisories.
While hospitals have been bracing for the peak of flu season, doctors are reporting a concerning rise in Pertussis (Whooping Cough). Known as the “100-Day Cough” because of its grueling duration, the bacterial infection is surging in communities where vaccination rates have dipped or immunity has waned.
According to the Virginia Department of Health (VDH), case numbers for early 2026 are significantly higher than the five-year average, with outbreaks concentrated in school districts and university towns.
The Hotspots: Where is it Spreading?
The surge is currently most intense in three specific regions. If you live or work in these areas, you are in a high-transmission zone:
- Northern Virginia (Fairfax & Loudoun Counties): The Fairfax Health District has reported a sharp increase in cases, largely affecting middle school students and their parents.
- Central Virginia (Lynchburg Area): A significant cluster has been identified in Lynchburg and surrounding Campbell County, particularly impacting college students and local religious communities.
- Blue Ridge Health District: Urgent care centers in the Charlottesville and Albemarle County area have flagged an “uptick” in patients testing positive for Pertussis this week.
Is it a Cold, the Flu, or the ‘100-Day Cough’?
The “100-Day Cough” is notoriously difficult to catch early because it mimics a harmless cold for the first 7 to 10 days. By the time the severe coughing starts, the person has already been contagious for a week.
Here is how to distinguish the symptoms of the “100-Day Cough” (Pertussis) from the current flu strain:
- The Cough Type: Pertussis causes violent, uncontrollable coughing fits that may end with a “whoop” noise or vomiting. The flu typically causes a dry, steady cough.
- Duration: This is the biggest difference. The flu usually lasts 5 to 7 days. Pertussis can last for 2 to 12 weeks.
- Fever: Pertussis usually presents with a mild fever or no fever at all. The flu brings a high fever (100°F+) that hits suddenly.
- How You Feel: With Pertussis, you often feel fine between coughing fits. With the flu, you feel exhausted and achy all the time.
Warning for Parents: In infants, the tell-tale “whoop” noise is often missing. Instead, watch for “apnea”—where the baby pauses breathing, turns red or blue, or struggles to catch their breath. This is a medical emergency.
Why is This Happening Now?
Virginia health experts cite a “perfect storm” of factors driving the 2026 surge:
- Waning Immunity: The Tdap vaccine (which protects against Pertussis) fades after about 10 years. Many adults have not had a booster since adolescence.
- The “College Effect”: The outbreak in the Lynchburg area highlights how easily the bacteria spreads in dorms and classrooms, eventually spilling over into the wider community.
The Action Plan: What to Do Today
- Check Your ‘Tdap’ Status: If it has been more than 10 years since your last tetanus/pertussis shot, you are likely vulnerable. Pharmacies like CVS, Walgreens, and Giant across Virginia have the vaccine in stock.
- The “Vomit” Test: If you or your child coughs so hard that it causes gagging or vomiting, do not assume it is a cold. Ask your doctor specifically for a Pertussis PCR test.
- Cocoon the Vulnerable: If you are visiting a newborn or an immunocompromised relative, ensure you are boosted. This “cocooning” strategy is critical, as Virginia hospitals are seeing a rise in infant admissions this month.
Stay safe, Virginia. Share this alert with neighbors and family members in Fairfax, Lynchburg, and Charlottesville to help stop the spread.
