Microbial Disease Report
Select a disease that affects humans or animals whose causative agent is a bacterium, virus, fungus, protozoa, or other microorganism. ( I chose hepatitis B)
Create and deliver a presentation on your chosen disease in which you report on each of the following in detail:
Causative Agent: Describe and classify the microbe involved. If known, explain how the microbe causes/transmits the disease or interferes with normal body function. Also, describe the vector and/or life cycle for the microbe (if applicable).
Population(s) affected: What population(s) is/are at highest risk of contracting the disease? Are there any groups of people who should be tested? Please include statistical/geographical data and trends (from the Centers for Disease Control and Prevention, World Health Organization, or other source [http://www.cdc.govLinks to an external site., http://www.who.intLinks to an external site., etc.]).
Course of Disease: What are the usual signs/symptoms of someone with the disease? How is the disease diagnosed? What is the usual time course for recovery? Are there complications and/or long-term effects?
Interventions: Describe possible treatments and/or medical interventions. Is there a vaccine available? How can the disease be best prevented or kept under control?
Sure, here is a presentation on Hepatitis B:

Speaker Notes Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). In today's presentation, we will discuss the cause, transmission, symptoms, and prevention of Hepatitis B.

- Hepatitis B virus (HBV)
- Double-stranded DNA virus
- Hepadnavirus family
- Cannot replicate on its own
- HBV is transmitted through contact with infected body fluids
- Blood
- Semen
- Vaginal fluids
- Saliva (in high concentrations)
- Contact with infected blood, such as from a needlestick injury or from sharing needles or syringes with someone who has hepatitis B
- Sexual contact with an infected person
- From an infected mother to her newborn baby during childbirth or shortly after birth
- Infants born to mothers with HBV
- People who have multiple sexual partners
- Men who have sex with men (MSM)
- People who inject drugs
- People who receive frequent blood products or blood transfusions
- Healthcare workers
- Travelers to areas with high HBV rates
- Infants born to mothers with HBV: Because of shared bodily fluids during childbirth or shortly after birth.
- People with multiple sexual partners: Increased risk of exposure to infected bodily fluids.
- Men who have sex with men (MSM): Higher risk of exposure during sexual contact.
- People who inject drugs: Sharing needles and syringes with infected individuals.
- People who receive frequent blood products or blood transfusions: Risk associated with blood products.
- Healthcare workers: Risk of needlestick injuries or exposure to infected body fluids.
- Travelers to areas with high HBV rates: Particularly if engaging in activities that could increase exposure to bodily fluids.
- Acute Hepatitis B:
- May not experience any symptoms
- Fatigue
- Loss of appetite
- Nausea and vomiting
- Abdominal pain
- Dark urine
- Jaundice (yellowing of the skin and whites of the eyes)
- Chronic Hepatitis B:
- Often no symptoms
- May experience fatigue, weakness, or abdominal pain
- Acute Hepatitis B: Some people with acute hepatitis B may not experience any symptoms at all. However, some common symptoms include fatigue, loss of appetite, nausea and vomiting, abdominal pain, dark urine, and jaundice (yellowing of the skin and whites of the eyes). These symptoms typically appear within 1-6 months after exposure to the virus.
- Chronic Hepatitis B: Many people with chronic hepatitis B don't have any symptoms. However, some people may experience fatigue, weakness, or abdominal pain. It's important to note that chronic HBV infection can lead to serious liver damage, including cirrhosis (scarring of the liver) and liver cancer.
- Blood tests
- HBsAg test: Detects the presence of the hepatitis B surface antigen, which indicates current
