16 conditions
Dengue Fever

Tuberculosis (TB)
A serious bacterial infection caused by Mycobacterium tuberculosis that primarily affects the lungs but can spread to other organs, transmitted through airborne droplets.
HIV/AIDS
Human Immunodeficiency Virus (HIV) attacks the immune system, specifically CD4 cells. Without treatment, it progresses to AIDS (Acquired Immunodeficiency Syndrome), leaving the body vulnerable to opportunistic infections.
Hepatitis B

Meningitis
A serious infection causing inflammation of the protective membranes (meninges) surrounding the brain and spinal cord. Bacterial meningitis is a medical emergency that can be fatal within hours.
Shingles (Herpes Zoster)
A painful, blistering rash caused by reactivation of the chickenpox virus (varicella-zoster), typically appearing in a band on one side of the body.
Chickenpox (Varicella)
A highly contagious viral infection causing an itchy, blister-like rash. Before routine vaccination, it was a common childhood illness; now largely preventable.
Measles (Rubeola)
A highly contagious viral disease characterized by fever, cough, runny nose, red eyes, and a distinctive red rash. Preventable by vaccination but can cause serious complications.
Sepsis
A life-threatening medical emergency that occurs when the body's response to infection damages its own tissues, potentially leading to organ failure and death.
Nipah Virus Infection
A rare but deadly zoonotic virus that causes severe encephalitis (brain swelling) and respiratory illness, transmitted from fruit bats to humans, with a fatality rate of 40-75%.

Hantavirus (Hantavirus Pulmonary Syndrome)
A rare but serious viral infection caused by hantaviruses, transmitted primarily through contact with rodent urine, droppings, or saliva. Causes severe respiratory failure with 30-40% mortality. Currently in news due to May 2026 cruise ship outbreak involving the rare Andes strain capable of person-to-person transmission.
