Study Notes
Communicable Diseases
- Communicable diseases are caused by various disease agents
- Understanding these agents is crucial in prevention, diagnosis, and treatment.
Bacteria
- Bacteria are single-celled microorganisms that thrive in various environments.
- Some bacteria are beneficial; others cause diseases.
-
Examples:
- Tuberculosis (TB) caused by Mycobacterium tuberculosis (affects lungs)
- Strep Throat caused by Streptococcus pyogenes (sore throat and fever)
- Bacterial Meningitis (inflammation of protective membranes covering brain and spinal cord) caused by various bacteria.
-
Characteristics:
- Prokaryotic cells (lack a nucleus)
- Asexual reproduction through binary fission
- Treatment: Antibiotics are effective against bacterial infections.
Viruses
- Viruses are microscopic, infectious agents needing a host cell to replicate.
- Not considered living organisms as they cannot reproduce independently.
-
Examples:
- Influenza caused by influenza virus (respiratory illness)
- HIV/AIDS caused by human immunodeficiency virus (affects immune system)
- COVID-19 caused by SARS-CoV-2 virus (primarily affects respiratory system)
-
Characteristics:
- Consist of genetic material (DNA or RNA) enclosed in a protein coat.
- Must infect a host cell to replicate.
- Treatment: Antiviral medications can help manage symptoms; vaccines are crucial for prevention.
Fungi
- Fungi are diverse organisms, unicellular or multicellular.
- Some are beneficial; others cause infections.
-
Examples:
- Candidiasis (mouth or genital area) caused by Candida species
- Athlete's Foot (skin infection) caused by dermatophytes.
- Histoplasmosis (respiratory disease) from inhaling fungal spores from contaminated soil (e.g., bird or bat droppings.)
-
Characteristics:
- Eukaryotic cells with a defined nucleus.
- Reproduction through spores (sexual or asexual).
- Treatment: Antifungal medications are used to treat fungal infections.
Parasites
- Parasites are organisms living on or in a host, benefiting at the host's expense.
- Can be unicellular or multicellular.
-
Examples:
- Malaria caused by Plasmodium species (transmitted by Anopheles mosquitoes)
- Giardiasis caused by Giardia lamblia (gastrointestinal issues)
- Toxoplasmosis caused by Toxoplasma gondii (affects individuals with weakened immune systems).
-
Characteristics:
- Structure varies widely (eukaryotic like protozoa or helminths).
- Reproduction can be sexual or asexual depending on the type.
- Treatment: Antiparasitic medications are used for treatment.
Communicable Disease Transmission
- Communicable diseases can spread through various routes, including:
- Direct contact (e.g., touching, saliva)
- Indirect contact (e.g., contaminated surfaces)
- Airborne transmission (e.g., respiratory droplets)
- Vector-borne transmission (e.g., insect bites)
Common Communicable Diseases
- Influenza Flu: Caused by influenza viruses (A, B, and C); symptoms include fever, cough, sore throat, body aches, etc., transmitted via airborne droplets, touching surfaces, and face touching.
- Chickenpox: Caused by varicella-zoster virus (VZV). Symptoms include itchy blister-like rash, fever, etc. transmitted via airborne transmission and direct contact with rash.
- Tuberculosis: Caused by Mycobacterium tuberculosis bacteria. Symptoms include persistent cough, chest pain, etc. transmitted via airborne transmission.
- COVID-19: Caused by SARS-CoV-2 virus. Symptoms include fever, cough, breathing difficulties, etc. transmitted via airborne transmission, close contact, and surface touching.
- Measles: Caused by measles virus. Symptoms include high fever, cough, runny nose, red eyes, rash, etc. transmitted via airborne transmission.
- Hepatitis A: Caused by hepatitis A virus (HAV). Symptoms include fatigue, nausea, vomiting, abdominal pain, etc. transmitted via fecal-oral route and close contact.
- Norovirus: Caused by norovirus. Symptoms include vomiting, diarrhea, nausea, etc. transmitted via contaminated food, water, and surfaces.
Other Diseases
- Black Death (Bubonic Plague) caused by Yersinia pestis bacterium transmitted via flea bites and direct contact.. Symptoms include swollen lymph nodes (buboes), fever, chills, weakness.
- Spanish Flu (H1N1 influenza) Pandemic (1918-1919), caused by H1N1 virus. Symptoms include fever, cough, sore throat, body aches, rapid progression of symptoms, Pneumonia.
SARS and H1N1
- SARS: Caused by SARS-CoV virus. Symptoms include fever, cough, shortness of breath, pneumonia.
- H1N1: Caused by H1N1 influenza virus. Symptoms include fever, cough, sore throat, body aches, headache, chills, and fatigue.
