The pain of viral infections is often described as itchy or burning. [11] The classic symptoms of a bacterial infection are localized redness, heat, swelling and pain. One of the hallmarks of a bacterial infection is local pain, pain that is in a specific part of the body. For example, if a cut occurs and is infected with bacteria, pain occurs ...
Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [1] Pneumonia can be caused by bacteria, viruses, fungi or parasites. [1] Viruses are the most common cause of pneumonia in children, while in adults bacteria are a more common cause. [2]
Vaccination prevents against certain bacterial and viral pneumonias both in children and adults. Influenza vaccines are modestly effective at preventing symptoms of influenza, [12] [87] The Centers for Disease Control and Prevention (CDC) recommends yearly influenza vaccination for every person 6 months and older. [88]
After years of low incidence, such bacterial infections reemerged worldwide in 2023. Pneumonia, which can be bacterial, viral, fungal, or parasitic, comes in many forms.
[1] [6] Symptoms usually last 3–5 days, but can be longer depending on cause. [2] [3] Complications can include sinusitis and acute otitis media.

[2] Strep throat, a bacterial infection, is the cause in about 25% of children and 10% ...
It is unclear if rapid viral testing in the emergency department for children with acute febrile respiratory infections reduces the rates of antibiotic use, blood testing, or urine testing. [11] The relative risk reduction of chest x-ray utilization in children screened with rapid viral testing is 77% compared with controls. [11]
Croup (/ k r uː p / KROOP), also known as croupy cough, is a type of respiratory infection that is usually caused by a virus. [2] The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of "barking/brassy" cough, inspiratory stridor and a hoarse voice. [2]
A routine chest X-ray is not always necessary for people who have symptoms of a lower respiratory tract infection. [4] Influenza affects both the upper and lower respiratory tracts. [citation needed] Antibiotics are the first line treatment for pneumonia; however, they are neither effective nor indicated for parasitic or viral infections. Acute ...
