List of infectious diseases
The various causes of common infectious diseases are bacteria, fungus, parasites, prions and viruses.
Bacterial infectious diseases
- Anthrax : multiplication of Bacillus anthracis in the body.
- Bacterial meningitis : inflammation of the protective membranes of the central nervous system.
- Botulism : blockage of nerve function and respiratory as well as musculoskeletal paralysis.
- Brucellosis : entrance of Brucella bacteria by direct contact or untreated/contaminated milk of animals.
- Campylobacteriosis : an inflammatory and at times bloody diarrhea or dysentery.
- Cat scratch disease : after 7 to 14 days or 2 months after a cat scratch, tender regional lymphadenopathy, slight fever, headache, chills, malaise, abdominal pain, backache, convulsions or sterile suppurative papules at the site of inoculation occur.
- Cholera : transmission of Vibrio cholerae by ingestion of contaminated food or water causes diarrheal disease.
- Diphtheria : upper respiratory tract illness having sore throat, low-grade fever and an adherent layer on the tonsils, nasal cavity, pharynx.
- Epidemic Typhus : caused by louse-borne bacteria.
- Gonorrhea : common sexually transmitted disease caused by Neisseria gonorrheae.
- Impetigo : superficial skin infection common in the age group of 2 to 6.
- Legionellosis : pneumonia or mild respiratory illness like acute influenza.
- Leprosy (Hansen's disease) : granulomatous disease of the peripheral nerves and mucosa of the upper respiratory tract.
- Leptospirosis : biphasic disease with meningitis, liver damage and renal failure.
- Listeriosis : occurs in newborn infants, elderly people and immunocompromised patients.
- Lyme disease : rash and flu symptoms followed by musculoskeletal, psychiatric, neurologic, arthritic and cardiac manifestations.
- Melioidosis : caused by Burkholderia pseudomallei, which is found in soil and water.
- MRSA infection : characterized by quick weight loss and muscle depletion.
- Nocardiosis : Nocardia asteroides or Nocardia brasiliensis affects either the lungs or the entire body.
- Pertussis (Whooping cough) : severe hacking cough followed by high intake of breath.
- Plague : occurs when person is bitten by an infected flea.
- Pneumococcal pneumonia : illness of the lungs and respiratory system where the alveoli are inflammed and filled with fluid.
- Psittacosis : contracted from parrots, pigeons, hens, ducks, sparrows and sea gulls.
- Q fever : due to inhalation of contaminated particles in the air or contact with the vaginal mucus, milk, feces, semen, urine of infected animals.
- Rocky Mountain Spotted Fever : most severe rickettsial illness in the United States.
- Salmonellosis : causes typhoid fever, paratyphoid fever and foodborne illness.
- Scarlet fever : infection may occur through bloodstream or skin and underlying tissues.
- Shigellosis : dysentery due to poor hygiene.
- Syphilis : sexually transmitted disease due to sexual contact or congenital mode.
- Tetanus : prolonged contraction of skeletal muscle fibers.
- Trachoma : infectious disease of human eye probably leading to blindness.
- Tuberculosis : generally attacks the lungs but may affect central nervous system, circulatory system, lymphatic system, bones, joints, genitourinary system and skin.
- Tularemia : heachache, fatigue, muscle pains, dizziness, nausea, loss of appetite, inflammation of face and eyes and lymph nodes.
- Typhoid fever : due to ingestion of food or water adulterated with feces of an infected person.
- Typhus : severe headache, sustained high fever, severe muscle pain, rash, cough, chills, stupor, decreasing blood pressure, delirium characterize it.
- Urinary tract infections : cystitis or pyelonephritis.
- Aspergillosis : allergic bronchopulmonary aspergillosis or pulmonary aspergilloma or invasive aspergillosis.
- Blastomycosis : inhalation of fungus from the natural soil habitat.
- Candidiasis : found in exposed and moist parts of the body like the vagina, vulva, penis, foreskin, skin around nostrils, nostrils, ear, oral cavity, nipples, folds of skin in diaper area.
- Coccidioidomycosis : caused by inhalation of airborne, fungal particles called arthroconidia.
- Cryptococcosis : caused by inhalation of soil contaminated with the encapsulated yeast.
- Histoplasmosis : pr
