Disease Causative Agents

Elephantiasis is a chronic disease caused by parasitic worms that block lymphatic vessels, causing severe swelling and long-term disability. It persists for years and often requires lifelong management. Smallpox (now eradicated) was acute, while fever and cough are symptoms, not diseases themselves.

Most skin infections like ringworm, athlete's foot, and fungal dermatitis are caused by fungi. While bacteria and viruses can also cause skin infections, fungal infections are among the most common. Mosquitoes are vectors that transmit diseases but don't directly cause skin infections.

Influenza is an acute disease that typically resolves within 1-2 weeks. Elephantiasis, ascariasis, and tuberculosis are chronic conditions that persist for long periods or require extended treatment.

Tuberculosis is a chronic disease that can last for months or years, even though it has acute phases. Headache, diarrhea, and common cold are acute conditions with short durations.

Rabies is transmitted through the bite of infected animals like dogs, bats, or raccoons. Typhoid is food/water-borne, tetanus enters through wounds but is not specifically from animal bites, and AIDS is sexually transmitted or through blood.

Malaria is transmitted through mosquito bites (vector-borne), not through air. Common cold, pneumonia, and tuberculosis spread through airborne droplets when an infected person coughs or sneezes.

AIDS (HIV) is transmitted through sexual contact, blood transfusion, or from mother to child - not through air. Common cold, pneumonia, and tuberculosis spread through airborne respiratory droplets.

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. Tetanus enters through wounds, diphtheria through respiratory droplets, and constipation is not a communicable disease.

Hemophilia is a genetic disorder that affects blood clotting and is inherited from parents, not caused by pathogens. Cholera, typhoid, and malaria are all infectious diseases caused by bacteria or parasites that spread from person to person or through vectors.

Yes, it is correct. It is an air borne diseses. Patient should be kept in isolation.

STDs caused by viruses are not curable. Herpes, HPV/genital warts and HIV are such examples. They can all be treated to control symptoms or help a person live a healthier life. Hepatitis B infection can be prevented if a person gets the vaccine before he or she is exposed to the virus. Unfortunately, there currently aren’t any cures for viral infections.

Sickle cell anemia patients have functional asplenia due to autoinfarction, impairing their ability to clear encapsulated bacteria. Pneumococcus (Streptococcus pneumoniae) is the most common cause of severe infection in these patients, along with meningococcus and H. influenzae type B.

Syphilis is caused by the bacterium Treponema pallidum, not a virus, parasite, or protozoan. It is a sexually transmitted infection (STI) that can be treated with antibiotics, particularly penicillin. Understanding that syphilis is bacterial is important because it determines the correct treatment approach - antibiotics for bacteria, not antivirals or antiprotozoals.

Black water fever is a severe complication of malaria, particularly falciparum malaria, characterized by massive hemolysis of red blood cells leading to dark or 'black' urine (hemoglobinuria). It causes kidney damage and can be fatal if not treated promptly.

Elephantiasis is caused by Wuchereria, a parasitic worm.
