Study Notes
Flu and Cold Symptoms
- Flu symptoms appear more rapidly and intensely than cold symptoms.
- Both flu and cold can be spread through direct and indirect contact.
- Rest and hydration are essential for faster recovery from the flu.
- Some flu strains can be severe and need medical attention.
- The flu season typically lasts from December to March, with peak cases reported during this time.
- Flu viruses differ from cold viruses, with yearly variations in dominant strains.
- Scientists annually predict the most harmful flu strains to develop future vaccines.
Historical Context of Influenza
- A significant flu outbreak after World War I resulted in approximately 20 million global deaths, including over 600,000 in the U.S.
- Ongoing scientific efforts aim to prevent such devastating flu outbreaks in the future.
Communicable Diseases and Contagious Periods
- All communicable diseases have a contagious period, often starting before symptoms appear.
- Chicken pox is contagious a week prior to symptoms; symptoms include itchy rash and fever.
- Measles, marked by rash and fever, can be spread a few days before symptoms and up to five days after.
- Mumps is contagious about a week before symptoms and for nine days after; common symptoms include fever and swollen glands.
- Vaccination has significantly reduced incidences of chicken pox, measles, and mumps in vaccinated populations.
Mononucleosis (Mono)
- Known as the "kissing disease," primarily affecting teens and young adults due to kissing and close contact.
- Spread through saliva and contaminated items; symptoms include sore throat, swollen lymph nodes, and fatigue.
- Severe cases may involve an enlarged spleen and liver complications.
- Rest is the primary treatment; immunity is developed after recovery.
Hepatitis
- Symptoms include yellowing skin, liver inflammation, fatigue, and appetite loss.
- Three main strains exist: A, B, and C, each caused by different viruses.
- Hepatitis A is often linked to unsanitary conditions, with ongoing efforts to improve vaccine development.
Pneumonia
- Caused by bacteria or viruses that infect the lungs after spreading from sinuses or directly from contaminated individuals.
- Symptoms include fever, cough, chills, and difficulty breathing.
- Spread can occur through contact with infected persons, symptomatic or not.
- Bacterial pneumonia is treatable with antibiotics; viral pneumonia with antivirals.
- Risk factors include pre-existing conditions like diabetes or HIV/AIDS and can be mitigated through vaccination and good hygiene practices.
Strep Throat
- More severe than common sore throats; caused by bacteria and treatable with antibiotics.
- Spread through respiratory droplets from infected individuals.
- Symptoms consist of sore throat, fever, and swollen lymph nodes; medical attention is advised for significant symptoms.
Common Cold
- Highly prevalent, with most individuals experiencing at least one each year.
- Symptoms include runny nose, headache, sore throat, and mild fever.
- Hundreds of viruses are responsible, complicating the development of a universal vaccine.
- It is crucial to cover the mouth while sneezing to limit spread; staying home for the first 24 hours is recommended to avoid infecting others.
