Should You Get the Fall Flu Shot? What Caregivers Need to Understand

A few winters ago my next-door neighbor panicked because her elderly mother was running a fever and coughing nonstop and didn’t know whether this was the flu, covid, or just a cold — or should she take her mother to the ER? This is a common occurrence across many families each winter when colds and other upper-respiratory infections appear to converge. Even doctors may require testing to determine what is causing the suffering of a family member who is sick. The Angel Care Inc. team explains the differences between these upper-respiratory infections, which can help you decide how to treat them and when to see a doctor. The Common Cold: The Inconvenience of Being Sick You’ve likely experienced the same thing. A scratchy throat that begins on a Monday morning, sniffles by Tuesday, and by Wednesday you’re going through boxes of tissues faster than you ever thought possible. The common cold is brought on by several types of viruses (the primary culprits are rhinovirus) and while it’s frustrating, most people aren’t at risk of serious harm. Cold symptoms typically include: Developed over the course of one or two days Stuffy/runny nose Slightly sore throat Some sneezing Very light cough Mild body aches and/or exhaustion Low-grade fever (more typical of children) As stated, “mild” is the operative term here. While the discomfort associated with colds is definitely noticeable, it is manageable. You’ll likely still attend to your job responsibilities while feeling unwell; you won’t be bedridden. Most colds will clear up on their own in 7-10 days although the cough may continue for a little longer. One of the unique aspects of colds is their progression. You’ll find that the symptoms build upon each other gradually – that tickly sensation in your throat develops into a stuffier nose on day 2, and reach their peak in terms of misery sometime between days 3 and 4, before beginning to subside again. This is a familiar pattern for many of us, having gone through this multiple times. Influenza: When "The Flu" is More Than Just a Bad Cold Many people are confusing. People will say they have the flu when they simply have a terrible cold. True influenza is significantly worse than that. I vividly remember getting true influenza years ago. I was fine at lunchtime, a little off by midafternoon, and by nightfall I was shaking under three blankets and had a fever of 103°F. This rapid escalation is a hallmark of flu. True flu symptoms typically include: Sudden, dramatic onset in hours Extreme fever (100-104° F or higher) Severe body aches and muscle pain Exhaustion and weakness Dry cough Headache Chills and sweats Infrequently, nausea, vomiting, or diarrhea (commoner in children) Flu generally lasts five to seven days for the acute phase, although fatigue can last for weeks. The main concern with influenza isn't the flu virus itself, but rather the potential for complications such as pneumonia, bronchitis, and sinus infections, as well as exacerbating underlying chronic conditions. COVID-19: The Unknown Variable More than three years after the pandemic started, COVID-19 is still difficult to predict. Some people don’t even realize they have it, while others become severely ill. These unpredictable symptoms make it difficult for caregivers to determine what ailing family members are experiencing. While current COVID-19 variants have produced some variations in symptomatology, common symptoms include: Chills/Fever Dry cough (can also produce phlegm) Fatigue (can range from slight to extremely debilitating) Shortness of breath Loss of taste/smell (although less common with newer variants) Sore throat Headache Muscle aches Runny/stuffy nose Nausea/Vomiting/Diarrhea Unlike colds, flu and other upper-respiratory infections, COVID-19 presents with a high degree of unpredictability. Family members who begin with a minor sore throat and congestive issues similar to a cold could develop breathing problems within days. Other family members can experience debilitating fatigue that persists for months -- known as "long COVID." The onset of symptoms can vary as well. Like flu, some people may develop symptoms quickly, while others develop symptoms gradually like a cold. This is another reason why testing became so critical. RSV: It’s Not Just for Babies & Toddlers Anymore Until recently, the majority of people were only aware of Respiratory Syncytial Virus (RSV) when they had young children or worked with pediatricians. However, we are now recognizing RSV as a major threat to the elderly and anyone whose immune system is weakened. Adults with RSV typically present with: Runny/congested nose Cough (which can be very severe) Difficulty breathing/wheezing Fever Less interest in food Fatigue Older adults with RSV can be at particular risk of developing serious complications, such as pneumonia or exacerbation of heart and lung disease. Older adults’ symptoms can initially be mild – simply feeling a little off – but can escalate rapidly in susceptible individuals. Comparative Chart: The Key Differences Below is a side-by-side chart comparing the differences in these illnesses: Feature Common Cold Influenza COVID-19 RSV Onset Speed Gradual (1-2 days) Sudden (hours) Variable Gradual Fever Rare (low-grade) High (100-104°F+) Common Common Body Aches Mild Severe Moderate to severe Mild to moderate Fatigue Mild Severe Variable (mild to severe) Moderate Cough Mild Can be severe Variable Often severe Shortness of Breath Rare Sometimes Common warning sign Common in severe cases Loss of Taste/Smell Temporary with congestion Rare Distinctive symptom Rare Typical Duration 7-10 days 5-7 days (fatigue longer) Variable (weeks to months) 1-2 weeks When to Seek Immediate Medical Attention Knowing when to escalate the level of care is vital, especially for caregivers caring for vulnerable individuals. While most respiratory infections are treated at home, there are specific warning signs that indicate a visit to the emergency department is necessary: Seek immediate emergency care if you notice: Difficulty breathing or shortness of breath when resting Prolonged chest pain or tightness Confusion or being unable to remain awake Blue lips or face Persistent vomiting Fever greater than 103°F that does not abate with medication Symptoms that begin to improve and then worsen Significant dehydration (reduced urine output, extreme thirst, dizziness) For older adults and/or those with ongoing health challenges, even mild symptoms warrant close monitoring. A seemingly minor cold can rapidly progress to a potentially life-threatening condition in someone with a compromised health status. Practical Care Ideas That Really Work Regardless of which viral infection you are experiencing, some care ideas provide legitimate relief: Rest is not optional. Your body is working to fight off the infection and that takes a tremendous amount of energy. Pushing through the illness will result in extended recovery time and an increased risk of complications. Fluid intake is more critical than you would believe. Fever, sweat, and respiratory symptoms can cause you to lose fluids. Drinking plenty of water, warm beverages, warm broths, and electrolyte-containing liquids can help keep you hydrated. As a general guideline: if your urine is darker than normal, you are dehydrated. Humidity can provide unexpected relief. Dry air irritates your already inflamed respiratory tract. Humidifying the air with a cool-mist humidifier, taking steamy showers, or even placing a bowl of boiling water on the table can help alleviate symptoms. Proper nutrition aids in recovery. Although your appetite may disappear, your body still requires nutrients. Easy-to-digest foods, such as soups, toast, bananas, and applesauce, provide calories without overwhelming your stomach. Monitoring your symptoms systematically is helpful. Keeping a basic record of temperature, symptom intensity, and any changes in symptoms will allow you to identify patterns and provide useful information to your healthcare provider.
