Understanding Flu, COVID-19, and Pertussis (Whooping Cough) 
As we approach the holiday season, it’s important to be aware of the increased spread of respiratory illnesses, including influenza (flu), COVID-19, and pertussis (whooping cough). These viruses and bacterium spread more easily during colder weather and social gatherings, so staying informed and following preventive measures is key to protecting yourself and those around you. 
  
Differences and Similarities Between Flu, COVID-19, and Pertussis 

Similarities:

  1. Transmission: 
    1. All three diseases are highly contagious and primarily spread through respiratory droplets when an infected person coughs, sneezes, or talks but can also spread by contact. Therefore, clean high touch surfaces frequently. 
    2. They are most commonly transmitted in crowded or poorly ventilated indoor spaces. 
  2. Symptoms: 
    • Common symptoms that can be shared by flu, COVID-19, and pertussis include: 
      • Fever or feeling feverish (not everyone with flu or pertussis will have a fever) 
      • Cough (persistent in pertussis, which causes severe coughing fits) 
      • Shortness of breath or difficulty breathing 
      • Fatigue (tiredness) 
      • Sore throat 
      • Runny or stuffy nose 
      • Muscle pain or body aches 
      • Headache 
      • Vomiting and diarrhea (more common in flu and COVID-19, especially in children) 
      • Loss of taste or smell (more common in COVID-19) 
      • With Pertussis, One coughs, violently and rapidly, until all the air has left the lungs, and a person is forced to inhale, causing a "whooping" sound 
      • Additional symptoms with pertussis are Sneezing, Nasal discharge, Sore & watery eyes, the lips, tongue, and nailbeds may turn blue during coughing spells.
  3. Prevention: 
    • Vaccination is the most effective prevention strategy for all three diseases. Make sure to stay up to date on your flu vaccine, COVID-19 vaccine, and pertussis (whooping cough) vaccine in Tdap
    • Other preventive measures include: 
      • Washing hands frequently 
      • Wearing masks in crowded or high-risk environments 
      • Maintaining physical distancing in public spaces 
      • Covering coughs and sneezes to limit the spread of germs 
      • Cleaning high-touch surfaces frequently. 
  4. Testing: 
    • Testing is essential to differentiate between these diseases, as their symptoms overlap. Dual testing for flu and COVID-19 can provide a more accurate diagnosis, and it's also possible to be infected with both at the same time, which can lead to more severe illness.
    • Pertussis is also diagnosed by use of nasal swab with a Respiratory Infection Battery. 
    • Home tests are available, but they can be less accurate than PCR tests, especially in asymptomatic cases, leading to a greater risk of false negatives.

Differences:

  1. Cause:
    1. Flu is caused by the influenza virus.
    2. COVID-19 is caused by the SARS-CoV-2 coronavirus.
    3. Pertussis is caused by the Bordetella pertussis bacteria, which primarily affects the airways and causes prolonged coughing fits.
  2. Incubation Period:
    1. Flu: Symptoms appear 1 to 4 days after exposure.
    2. COVID-19: Symptoms can appear 2 to 14 days after exposure, with a longer potential period of contagiousness.
    3. Pertussis: Symptoms usually appear 5 to 10 days after exposure, but the cough can persist for 10 weeks or more.
  3. Severity:
    1. COVID-19 can cause more severe illness, especially in high-risk individuals, leading to complications like pneumonia, organ failure, or even death. Some individuals also experience Long COVID, a prolonged set of symptoms.
    2. Flu typically results in milder symptoms for most healthy individuals, though it can also cause severe complications, particularly in children, the elderly, or those with chronic conditions.
    3. Pertussis can be severe in infants, young children, and those with compromised immune systems, potentially causing difficulty breathing and even death if not treated promptly.
  4. Contagious Period:
    1. COVID-19: People are contagious 2 to 3 days before showing symptoms and can spread the virus for up to 10 days.
    2. Flu: Individuals are most contagious in the first 3 to 4 days after becoming ill but can spread the virus for up to 7 days.
    3. Pertussis: Contagious from the beginning of symptoms until about 5 days after starting antibiotics.
  5. Treatment:
    • Flu treatment should start within 48 hours for the best effectiveness, though antivirals can still be used within 72 hours.
    • COVID-19 treatment must be started within 5 days of symptom onset for the best results.
    • Pertussis can be treated with antibiotics if caught early, but it may take weeks for the cough to subside, even with treatment.

Important Health Advisory for the Holiday Season
With the holiday season approaching and the colder weather encouraging more indoor gatherings, respiratory viruses like the flu, COVID-19, and pertussis tend to spread more rapidly. To help reduce the spread and protect yourself and others, we encourage the following preventive actions:

Preventative Measures:

  1. Get Vaccinated:
    • If you haven’t already, consider getting your flu, COVID-19, and pertussis (whooping cough) vaccines to reduce your risk of infection.
    • Vaccination is the most effective way to protect yourself and your community from these viruses.
    • The Tdap vaccine is a combination vaccine that protects against three serious bacterial diseases:
      • Tetanus (T)
      • Diphtheria (d)
      • Pertussis (ap) – also known as whooping cough.
        • Please Note: If you’ve already received the Tdap vaccine, you’re protected against tetanus, diphtheria, and pertussis (whooping cough), which are serious bacterial diseases. The vaccine is typically given during childhood and then as a booster dose during adolescence or adulthood, depending on your vaccination history.
        • Receiving the Tdap vaccine helps ensure that you have immunity against these illnesses, which can be particularly dangerous for infants, the elderly, and those with weakened immune systems. It’s important to stay up to date with booster shots, especially if it has been more than 10 years since your last dose.
  2. Practice Good Hygiene:
    • Wash your hands regularly with soap and water, especially before eating or after touching shared surfaces. If soap and water aren’t available, use hand sanitizer with at least 60% alcohol.
    • Cover your coughs and sneezes to limit the spread of germs.
  3. Wear a Mask:
    • In crowded indoor spaces, wearing a mask can help reduce the transmission of respiratory viruses, especially if you feel unwell.
  4. Stay Home When Sick:
    • If you have symptoms like fever, cough, or fatigue, stay home to prevent spreading the illness to others. This is crucial for the health of your peers and family.
  5. Improve Ventilation:
    • Open windows, use exhaust fans, and consider using HEPA air purifiers to improve indoor air quality, especially if you’re gathering indoors.
  6. Physical Distancing:
    • Maintain physical distance from others, when possible, especially if you are in indoor settings or have symptoms.

When to Seek Medical Help:

  • Flu: Seek care if you experience high fever, severe body aches, fatigue, or difficulty breathing. Contact your healthcare provider if symptoms worsen.  Treatment is required within 48 to 72 hours. 
  • COVID-19: If you experience fever, cough, shortness of breath, or loss of taste/smell, get tested for COVID-19 and seek medical care if your symptoms worsen or if you're at higher risk.  Treatment is required within 5 days. 
  • Pertussis: If you experience severe coughing fits, especially with a “whooping” sound or difficulty breathing, seek medical attention immediately. 
  • Respiratory Distress: If you have trouble breathing, persistent chest pain, confusion, or severe symptoms, seek immediate medical help.
