A healthcare provider draws a blood sample from your vein, which is then analyzed in a laboratory to determine your blood type.

Infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi, or parasites.

They can be transmitted through direct contact with an infected person, animal, insect bites, or contaminated food and water.

Symptoms vary but often include fever, fatigue, muscle aches, cough, and digestive issues.

Diagnosis involves physical examinations, medical history review, and diagnostic tests such as blood tests, cultures, and imaging.

Treatments may include antibiotics, antivirals, antifungals, antiparasitics, and supportive care depending on the type of infection.

Surgeons perform a rapid assessment to identify life-threatening conditions first, then proceed with necessary surgeries to stabilize the patient.
