Takeaways

• 🦠 COVID-19 is caused by SARS-CoV-2, a respiratory virus that spreads through aerosols and presents symptoms like fever, dry cough, and loss of taste or smell.
• 🤒 AIDS, caused by the HIV virus, weakens the immune system by attacking lymphocytes and has an incubation period of 10-15 years. It spreads through unprotected sex, shared needles, blood transfusions, and childbirth.
• 👂 Mumps causes swelling of the parotid glands and is a contagious disease.
• 🔥 Herpes infects epithelial cells and remains dormant in nerve cells after initial infection.
• 😷 Smallpox, caused by the variola virus, has an incubation period of 12 days and is preventable through vaccination.
• 🍃 Hepatitis affects liver function and can be transmitted via bodily fluids, or contaminated food and water. There are several types: A, B, C, and D.
• 🌬️ Influenza is a respiratory illness caused by the orthomyxovirus, with symptoms like chills, fever, and muscle pain.
• 🤧 Measles, caused by the morbillivirus, has an incubation period of 7-11 days and is marked by red spots, fever, and conjunctivitis.
• 🐔 Avian Influenza, or bird flu, is caused by H5N1 and transmits via respiratory droplets, causing symptoms similar to the common flu.
• 🦟 Dengue fever is caused by the dengue virus and spread by Aedes mosquitoes, leading to high fever, headaches, and potentially severe bleeding.

Q & A

What causes COVID-19 and how does it spread?

COVID-19 is caused by SARS-CoV-2, a new strain of coronavirus. It spreads through respiratory droplets in the air, also known as aerosols.

What are the common symptoms of COVID-19?

Common symptoms of COVID-19 include fever, dry cough, shortness of breath, loss of taste or smell, muscle pain, headache, and chest pain.

What is AIDS, and what causes it?

HIV/AIDS can be transmitted through unprotected sexual contact, sharing needles among drug users, receiving contaminated blood transfusions, and from a pregnant mother to her baby.

What is mumps, and how does it affect the body?

Mumps is a viral infection that causes the swelling of the parotid glands, which are the salivary glands. It is contagious and spreads easily.

What is herpes, and what does it affect?

Herpes is a viral infection that affects the epithelial cells of the skin and mucous membranes. After the initial infection, the virus remains dormant in the nerve cells.

What causes smallpox, and what is its incubation period?

Smallpox is caused by the variola virus. Its incubation period is approximately 12 days.

What are the types of hepatitis, and how is it transmitted?

Hepatitis is a viral infection that affects the liver. There are different types (A, B, C, and D), and it can be transmitted through bodily fluids or contaminated food and drink.

What is dengue fever, and how is it transmitted?

Dengue fever is caused by the dengue virus, transmitted through the bite of the Aedes aegypti mosquito. It is characterized by fever, headaches, and a drop in platelet levels, which can lead to bleeding.

What is the incubation period and symptoms of bird flu (Avian Influenza)?

The incubation period for bird flu is 1-7 days. Symptoms include fever, sore throat, cough, clear nasal discharge, muscle pain, headache, fatigue, shortness of breath, and pneumonia.
