Question: Why Are The Elderly More Susceptible To Respiratory Infections?

Aging is also accompanied by a gradual decline in many aspects of immune function, and waning immunity is thought to be an important risk factor for pneumonia in the elderly.

Why are the elderly more susceptible to pneumonia?

As people age, their immune systems work less well, leaving them less able to fend off infections. Heart disease, diabetes and other serious illnesses that are common in seniors increase risk of pneumonia. Seniors are more susceptible to the flu and other lung-related conditions, which sometimes develop into pneumonia.

Does respiratory rate increase with age?

Breathing rate usually does not change with age. But lung function decreases slightly each year as you age. Healthy older people can usually breathe without effort.

Which respiratory symptoms are common in older patients?

The most commonly reported pulmonary symptoms in the elderly include dyspnea, cough, and decreased exercise tolerance. These symptoms can be caused by a variety of pulmonary, as well as non-pulmonary, conditions. Cough with sputum is reported by up to 27% of elderly patients and is associated with increased mortality.

What are the 4 factors that make a person more susceptible to infection?

Life style risk factors such as aging, poor nutrition, infection and exposure to toxicants can also increase susceptibility to illnesses. These life style factors can therefore be considered to cause acquired susceptibility for increased risk for environmental disease.

What makes someone more susceptible to infection?

A susceptible person is someone who is not vaccinated or otherwise immune, or a person with a weakened immune system who has a way for the germs to enter the body. For an infection to occur, germs must enter a susceptible person’s body and invade tissues, multiply, and cause a reaction.
