Final answer:
Pneumonia affects people of all ages; both extremes of age, infants and the elderly, are at higher risk. The age range for pneumonia cannot be determined, and factors like pre-existing medical conditions and smoking can increase susceptibility. Vaccinations help prevent pneumonia, particularly in high-risk groups.
Step-by-step explanation:
The correct age range for pneumonia cannot be determined as it affects people of all ages. Pneumonia is a common illness that impacts individuals of any age group, including infants, children, adults, and the elderly. It can develop as a consequence of respiratory tract infections like the common cold or flu.
It is important to recognize that specific age groups may be at higher risk. For instance, pneumonia is more prevalent and can be more serious among young children, especially those under the age of 5, and older adults, typically those who are 65 years and older. These age groups often have higher infection rates due to a more vulnerable immune system, which can be less responsive in the very young and less robust in the elderly.
Vaccinations, such as the flu vaccine, are recommended for the prevention of pneumonia, especially for high-risk groups including infants starting at 6 months old and the elderly. Additionally, conditions like chronic lung diseases, heart failure, asthma, or habits such as smoking can increase the likelihood of developing pneumonia. For example, Smoking-Associated Pneumonia can occur, as presented in the case of Camila, a 22-year-old chronic smoker who developed pneumonia.
