Pneumonia is an inflammatory condition of the lung―affecting primarily the microscopic air sacs known as alveoli. Typical symptoms include a cough, chest pain, fever, and difficulty breathing.

Hospital-acquired pneumonia (HAP) or nosocomial pneumonia refers to any pneumonia contracted by a patient in a hospital at least 48–72 hours after being admitted. It is usually caused by a bacterial infection
Ventilator-associated pneumonia (VAP) is a sub-type of hospital-acquired pneumonia (HAP) which occurs in people who are receiving mechanical ventilation.

Causative organisms:-
Lower respiratory tract infections (LRTI)

Nosocomial and community acquired pneumonia caused by:

Pseudomonas aeruginosa Staphylococcus aureus (methicillin-susceptible strains) Streptococcus pneumoniae Escherichia coli Haemophilus influenzae
S. Pneumoniae H. influenzae

Gastroenteritis : A syndrome characterized by gastrointestinal symptoms including nausea, vomiting, diarrhea and abdominal discomfort

Diarrhea :  Abnormal fecal discharge characterized by frequent and/or fluid stool; usually resulting from disease of the small intestine and involving increased fluid and electrolyte loss.

Dysentery:-  An inflammatory disorder of the gastrointestinal tract often associated with blood and pus in the feces and accompanied by symptoms of pain, fever, abdominal cramps; usually resulting fromdisease of the large intestine

Enterocolitis : Inflammation involving the mucosa of both the small and large intestine . Important Pathogens responsible for GI infections
