A bladder infection, or cystitis, is a common urinary tract infection (UTI) caused by bacteria. Symptoms include frequent urination, burning during urination, and lower abdominal pain. It’s more common in women.  Prompt treatment prevents complications like kidney infections. Drinking water helps flush out bacteria.

Bronchitis is inflammation of the bronchial tubes, often caused by viruses or irritants like smoke. It leads to coughing, mucus production, chest discomfort, and shortness of breath. Acute bronchitis typically resolves in weeks, while chronic bronchitis is long-term. Treatment includes rest, fluids, and, if needed, inhalers or medications.

An ear infection is a buildup of fluid and inflammation in the middle ear, usually caused by bacteria or viruses. It often follows a cold or upper respiratory infection. Common symptoms include ear pain, trouble hearing, fussiness in children, and sometimes fever. Ear infections are especially common in young children.

Strep throat is a contagious bacterial infection caused by Streptococcus pyogenes. It leads to a sore, scratchy throat, pain when swallowing, fever, and swollen lymph nodes. Red spots or white patches may appear on the tonsils. It spreads through respiratory droplets and is most common in children and adolescents.
