Understanding Respiratory Infections in the Elderly
It's common for elderly adults to experience frequent coughing during the fall and winter months as respiratory viruses circulate. In particular, respiratory syncytial virus (RSV) is a leading cause of severe respiratory illness in older populations resulting in intense coughing spells.
What is Respiratory Syncytial Virus?
Respiratory syncytial virus is a highly contagious virus that infects the respiratory tract. While RSV mainly affects infants and younger children, it can also cause significant illness later in life among vulnerable elderly individuals.
In older adults, RSV usually starts out resembling the common cold with stuffy/runny nose, sore throat, and mild dry cough. However, RSV can quickly progress to lower respiratory tract infection leading to aggravated cough, wheezing, chest congestion, fever, and extreme fatigue in the elderly.
In severe cases, RSV infection results in pneumonia and respiratory failure requiring hospitalization. The cough is often the most troublesome symptom of RSV, especially in the elderly. Cough aggravates pain, interrupts sleep, and contributes to lightheadedness or dizziness due to strained abdominal muscles and bursting capillaries.
Why Do Senior Citizens Cough So Much with RSV?
Elderly adults are highly vulnerable to complications from respiratory infections for several reasons. Weakened immune systems have a harder time clearing viruses promptly leading to long-lasting symptoms.
Lung capacity, cilia function, and cough reflexes also decline with age resulting in mucus accumulating rather than being properly expelled. Underlying heart failure or chronic lung conditions like COPD further hamper the body's ability to oxygenate appropriately during infections.
Cough is the body's mechanism to try and clear congestion from the airways to improve breathing. But prolonged forceful coughing fits lead to exhaustion and distress. Infections like RSV strain already taxed respiratory and cardiac systems in seniors.
Preventing RSV Transmission to the Elderly
There are currently no vaccinations available to protect against RSV, though research is underway. RSV spreads similarly to colds or flu via:
- Airborne respiratory droplets inhaled after an infected person coughs or sneezes nearby
- Or through direct contact then touching eyes, nose or mouth before hand washing
- Contaminated surfaces like doorknobs, table tops, and bed rails also foster virus transmission
To reduce exposure risk, elderly individuals should avoid close contact with symptomatic people especially those with young children who may be infectious. Frequent, thorough hand washing also helps prevent transmission through contaminated surfaces.
Treating RSV Infections in the Elderly
There are no medications that specifically target RSV. Supportive treatments focus on relieving symptoms to keep older patients comfortable while their immune system fights the virus.
Cough Suppressants - Over-the-counter cough medicine with dextromethorphan as the active ingredient may provide temporary relief from coughing fits though often not very effective.
Expectorants - Guaifenesin as an active ingredient helps thin mucus secretions making coughs more productive at clearing phlegm and congestion from the airways.
Hydration - Fluids keep mucus secretions thinner and easier to clear. Broths, juices, herbal teas, electrolyte solutions or water prevent dehydration.
Humidifiers - Increasing moisture in the air eases respiratory distress and loosens mucus to suppress coughs. Offer plenty of fluids and use a cool mist humidifier.
Most RSV infections resolve without special medical intervention within 7-10 days. Seek emergency care if breathing difficulties rapidly worsen or fever spikes above 104F which may indicate secondary bacterial infection.
Reducing RSV Infection Severity
While RSV often cannot be prevented outright, especially during regional outbreaks, the following proactive measures may reduce infection severity in senior citizens:
- Ensure all recommended vaccinations like flu, TDAP, pneumonia, shingles and COVID are up to date
- Improve nutrition focusing on vitamin C, vitamin D, zinc and protein for immune support
- Ask doctor about preventive therapy options during RSV season for those extremely high risk
- Have any medications on hand for chronic conditions like COPD or heart failure
- Create emergency plans identifying quickly accessible support resources
RSV Precautions for Caregivers of Elderly Adults
For those caring for aging parents, spouses or other elder loved ones, be vigilant about identifying respiratory illness symptoms promptly to enable supportive treatment and isolation precautions.
RSV Warning Signs Requiring Medical Assessment
Seek medical evaluation immediately if the senior shows any of the following:
- Difficulty breathing or wheezing at rest
- Decreased alertness or sudden confusion
- Blue tinge to lips or nails indicating oxygen deprivation
- Chest pain or rapid heart rate with infection
Rapid medical intervention is necessary if respiratory distress intensifies or circulatory collapse risk increases. Prolonged oxygen deprivation risks organ damage or even sepsis.
Caring for RSV Patients at Home
For milder RSV cases, create a comfortable healing environment at home. Strategies include:
- Isolate sick areas to prevent transmission to other vulnerable household members
- Offer plenty of fluids, nutritious soups and high calorie foods
- Play relaxing music and keep lighting low to promote rest
- Provide soft tissues, cough drops and trash bins for easy access
- Use disinfecting wipes on all surfaces touched by infected person
- Encourage productive coughing and deep breathing exercises
- Monitor for improvement or worsening requiring medical consultation
With attentive at-home nursing care, most standard RSV cases in otherwise healthy seniors resolve without hospital level support. However, carefully monitor symptoms and do not hesitate getting emergency help if respiratory distress intensifies.
