Human Health and Disease
- Health was once considered a balance of "humors" (early Greek and Indian Ayurveda)
- Blood circulation and body temperature discoveries disproved some ideas
- Mental state and lifestyle affect health
- Genetic disorders, infections, and lifestyle choices affect health
- Lifestyle factors include diet, exercise, habits, and hygiene
- Diseases can be broadly categorized into infectious and non-infectious
- Health is a state of complete physical, mental, and social well-being
- Health is now understood to be the absence of disease and a state of physical, mental, and social well-being
Common Diseases in Humans
- Pathogens (bacteria, viruses, fungi, protozoans, helminths) can cause diseases
- Pathogens enter the body, reproduce, and damage tissues
- Pathogens adapt to the host environment, like withstanding low pH in the stomach
- Examples: Typhoid fever (Salmonella typhi), Amoebiasis(Entamoeba histolytica), Ascarias, Wuchereira
- Preventative measures and control methods are crucial
- Hygiene and sanitation are important
- A wide range of organisms cause human diseases
- Parasites like Ascaris and Wuchereria are pathogens
- Pathogens enter and cause damage to the body
Typhoid
- Bacterial disease caused by Salmonella typhi
- Infects the small intestine, then migrates to other organs
- Symptoms: high fever, weakness, stomach pain, constipation, etc.
- Severe cases can cause perforation or death, diagnosed using the Widal test
- Affects the intestinal system
Pneumonia
- Bacterial or viral respiratory infection
- Alveoli (air sacs) get filled with fluid, leads to breathing problems
- Symptoms: fever, chills, cough
- Transmitted through breathing in droplets or aerosols from an infected person
- Bacteria like Streptococcus pneumoniae and Haemophilus influenzae cause pneumonia
- Affects the respiratory system
Common Cold
- Viral infection of the nose and respiratory passages
- Generally characterized by nasal congestion, sore throat, cough, headache, and fatigue
- Lasts 3-7 days
- Spread via droplets from coughing or sneezing
- Affects the respiratory system
Malaria
- Protozoan disease caused by Plasmodium
- Requires two hosts, humans and mosquitos
- Symptoms: chills, fever, sweating
- Transmitted through the bite of infected female Anopheles mosquitoes
- Plasmodium vivax, Plasmodium malaria, Plasmodium falciparum are example species
- Affects the blood and liver systems
Amoebiasis
- Protozoan infection caused by Entamoeba histolytica
- Infection causes symptoms like constipation, abdominal pain, cramps, and bloody stools
- Spread through contaminated food and water
- Affects the digestive system
Elephantiasis
- Filarial worm infection, causing lymphatic vessel inflammation
- Causes swelling in lower limbs
- Transmitted through mosquito bites
- Affects lymphatic system
Ringworm
- Fungal infection causing skin lesions
- Characterized by dry, scaly lesions and intense itching
- Affects the skin
AIDS
- Acquired Immunodeficiency Syndrome
- Caused by the Human Immunodeficiency Virus (HIV)
- Virus attacks immune system, making person vulnerable to other infections
- Can be transmitted through specific routes (e.g., blood transfusions, sexual contact, childbirth)
- No cure, but treatment can prolong life
- Symptoms can include fever, diarrhea, and weight loss
- HIV replication involves viral RNA converting to viral DNA, then inserting into the host cell's DNA; new viruses assemble and leave the host cell.
- A condition of immune system deficiency
- A wide range of organisms cause human diseases
Cancer
- Uncontrolled cell growth
- Two types: benign (confined) and malignant (invasive)
- Caused by physical, chemical, or biological agents (carcinogens)
- Early detection improves treatment outcomes
- Detecting early can increase success rate through biopsies and imaging (X-rays, CT, MRI), surgery, radiation, or chemotherapy
- Cancer cells may metastasize to other parts of the body
- Cancers can be caused by viral oncogenes
- Cancers can be caused by oncogenic transformation of cells, which has a breakdown of regulatory mechanisms
- The immune system's ability to detect and destroy cancerous cells
Drug and Alcohol Abuse
- Increased use, especially among young people
- Harmful effects on health (physical, psychological, and social)
- Psychological attachment and tolerance increasing with use
- Can manifest in violence or reckless behavior
- Withdrawal symptoms may be severe
- Substance use leads to addiction, dependence, and social problems
- Examples of drugs include Opioids (Heroin, morphine), cannabinoids (marijuana, hashish), and coca alkaloids (cocaine)
- Substance abuse impacts multiple body systems
- Tobacco, a common substance used in smoking, can cause cancers and respiratory problems - including bronchitis, emphysema, and cancers of the lung, urinary bladder, and throat.
Immunity
- Innate immunity: present at birth, first line defense
- Physical, physiological (e.g., enzymes in tears, stomach acid), and cellular (e.g., phagocytes) barriers
- Acquired immunity: develops after exposure, specific to pathogen
- Active and passive immunity responses
- Different types of immunity responses to counter different pathogens
- Exposure to particular substances/microbes could stimulate the production of specific immune responses resulting in long-term immunity
Allergies
- Exaggerated immune response to allergens
- Allergens: substances like dust mites, pollen, animal dander
- Mast cells release histamines and other chemicals, causing symptoms (e.g., sneezing, itching, wheezing, breathing difficulties)
- Modern lifestyle and environmental factors may contribute to increased sensitivity
- An overreaction of the immune system toward common substances
Autoimmunity
- Body's immune system attacks its own tissues
- Rheumatoid arthritis is an example
- Immune system attacking self-cells causing harm
Lymphoid Organs
- Where lymphocytes develop and mature
- Bone marrow and thymus are primary lymphoid organs
- Lymph nodes, spleen, tonsils, Peyer's patches, appendix are secondary lymphoid organs
- Lymph nodes are small structures along lymph vessels that trap pathogens
- Mucosa-associated lymphoid tissue (MALT) is lymphoid tissue in major tracts (respiratory, digestive, urogenital)
- Important for immune response, filtering, and production of cells
