Bacterial infections can look different depending on how old you are. This is because our immune systems change as we age.

Infants and Young Children:

• Example: Pneumococcal pneumonia is very serious for babies and young kids. It can cause them to have trouble breathing quickly and can lead to dehydration.

Adults:

• Example: In adults, this same infection might show up with milder signs like a cough and fever. However, it can get worse for those who have other health problems.

Elderly:

• Example: For older adults, infections like urinary tract infections might not show the usual signs. Instead, they can appear confused or feel really weak.

Knowing how these infections act in different age groups is super important. It helps doctors diagnose and treat patients more effectively.
