The Answer for Requirement Number 1

Public health is a multidisciplinary field focused on the prevention of illness and promotion of health within communities. It involves efforts to protect and improve the health of people by promoting healthy lifestyles, conducting research, implementing policies, and providing health services.

Let’s delve into some diseases, their forms, transmission vectors, prevention strategies, and treatments:

Escherichia coli (E. coli)BacterialContaminated food or water, uncooked meats, or person-to-personProper hygiene, safe food handlingAntibiotics
TetanusBacterial/ToxinThrough a wound from contaminated objectsVaccination, wound careAntitoxin, antibiotics
AIDSViralSexual contact, sharing needles, blood transfusion, from mother to childSafe sex, clean needles, screening bloodAntiretroviral therapy
EncephalitisViralMosquito or tick bites, sometimes through viruses spread by other animalsAvoiding vectors, vaccines where availableAntiviral medications, supportive care
SalmonellosisBacterialContaminated food or waterProper food handling and hygieneFluids, antibiotics in severe cases
Lyme diseaseBacterialTick bitesProtective clothing, tick checks, avoiding wooded areasAntibiotics
Coronavirus (COVID-19)ViralMosquitos or tick bites, sometimes through viruses spread by other animalsMasks, social distancing, vaccinationSupportive care, specific antiviral in some cases

Now let’s focus on four diseases from the second list:

GonorrheaBacterialSexual contactSafe sexAntibiotics
West Nile VirusViralMosquito bitesMosquito control, avoiding bitesSupportive care
BotulismBacterial/ToxinContaminated food or woundsProper food canning, wound careAntitoxin, supportive care
InfluenzaViralRespiratory droplets from infected personVaccination, good hygieneAntiviral medications, supportive care

This table outlines how each disease is contracted and potentially prevented, and the available treatments. Prevention methods often include vaccination, proper hygiene, and avoiding potential vectors. Treatments can range from antibiotics and antivirals to supportive care.

The Answer for Requirement Number 2a

Immunization, also known as vaccination, is a process by which a person’s immune system is prepared or strengthened to fight a particular disease. This is achieved by administering a vaccine, which is a substance that stimulates the body’s immune response.

When a vaccine is given, it introduces a weakened or harmless version of the pathogen (virus or bacteria) into the body. This doesn’t cause the disease but prompts the immune system to produce a response, including the production of antibodies. This process helps the immune system “remember” the pathogen.

So, if the person is later exposed to the actual disease-causing pathogen, their immune system is able to respond more rapidly and effectively because it recognizes the pathogen. This can prevent the disease from developing or reduce its severity.

In summary:

ImmunizationThe process of administering a vaccine to stimulate the body’s immune system to protect against specific diseases.

Remember, immunization not only protects individuals but also contributes to community or herd immunity, thereby protecting those who cannot be immunized due to health reasons.

The Answer for Requirement Number 2b,c

(b) Diseases against which a young child should be immunized, diseases requiring periodic reimmunization, and an annual immunization.

Young children should be immunized against the following diseases:

  1. Measles
  2. Mumps
  3. Rubella
  4. Diphtheria
  5. Tetanus
  6. Pertussis (Whooping Cough)
  7. Polio
  8. Haemophilus influenzae type b (Hib)

Diseases against which everyone should be reimmunized periodically:

  1. Tetanus (every 10 years)
  2. Pertussis (Whooping Cough)

Immunization everyone should receive annually:

  1. Influenza (Flu)

This table summarizes the aforementioned:

ImmunizationFrequencyTarget Age Group
Measles, Mumps, Rubella, Diphtheria, Tetanus, Pertussis, Polio, HibChild’s Immunization ScheduleYoung Children
Tetanus, PertussisPeriodically (Tetanus: every 10 years)Everyone

(c) Diseases from requirement 1b with no available immunization.

Looking back at the diseases mentioned in requirement 1b, the ones that currently have no immunization available include:

  1. AIDS
  2. Gonorrhea
  3. Syphilis
  4. Hepatitis C
  5. Herpes
  6. Lyme Disease
  7. E. Coli
  8. Salmonellosis
  9. Emphysema

While there are treatments and prevention strategies available for these diseases, there is currently no vaccination that provides immunity against them. However, research is ongoing for many of these conditions to develop effective vaccines.

It is also important to note that the best defense against many sexually transmitted diseases (like AIDS, gonorrhea, syphilis, and herpes) is prevention through safe sex practices.

The Answer for Requirement Number 3

Safe drinking water is paramount to public health. Many diseases, including cholera, dysentery, and typhoid, can spread through contaminated water. Unsafe water can become contaminated with microorganisms like bacteria and viruses, or substances like toxic metals and pesticides, which can lead to various health issues, including gastrointestinal illnesses and potentially life-threatening diseases.

When camping, making water safe to drink is crucial to prevent waterborne diseases. Here are two ways:

1. Boiling: This is the simplest and most effective way to make water safe. Bring water to a full boil for at least one minute, let it cool naturally, and store it in a clean container with a lid.

2. Water Purification Tablets or Drops: These products kill most bacteria, viruses, and other harmful organisms in the water. Always follow the manufacturer’s instructions.

Keeping dishes and utensils clean, both at home and in camp, is also essential for disease prevention. Here’s a simple approach:

  • Rinse: Remove excess food from dishes and utensils.
  • Wash: Use hot water and dish soap to thoroughly clean all surfaces.
  • Rinse Again: Rinse off all soap with clean water.
  • Sanitize: In a separate container, immerse the items in boiling water for at least one minute, or use a sanitizing solution.
  • Air Dry: Allow dishes and utensils to air dry. Avoid towel drying as it can introduce new germs.

Here’s a handy table:

1Rinse dishes and utensils to remove excess food.
2Wash with hot water and soap.
3Rinse again with clean water to remove soap.
4Sanitize by immersing in boiling water or using a sanitizing solution.
5Allow to air dry completely.

Remember, good hygiene practices, such as hand washing before handling food or dishes, are also crucial in preventing the spread of diseases.

The Answer for Requirement Number 4

A vector in public health terms refers to an organism, typically an insect or a rodent, that can carry and transmit infectious pathogens into other living organisms. Examples of vectors include mosquitoes, ticks, fleas, flies, and rats.

Vectors are of significant concern because they can spread diseases. For example, mosquitoes can transmit malaria or West Nile virus, and ticks can spread Lyme disease.

Controlling vectors at home, in the community, and at camp involves different methods:

Home and Camp:

  • Sanitation: Regular cleaning to eliminate food and water sources that attract these pests.
  • Exclusion: Sealing off entry points to prevent insects and rodents from entering.
  • Traps: Using traps or electronic devices for insects and rodents.
  • Chemical Control: Use of pesticides or insecticides, preferably by professionals.


  • Sanitation: Regular garbage collection and clean-up drives.
  • Public Education: Teaching people about the importance of cleanliness and preventive measures.
  • Integrated Pest Management (IPM): This is a collective, long-term approach that combines biological, physical, and chemical methods to control pests effectively.

Here’s a summary:

LocationVector Control Method
Home and CampSanitation, Exclusion, Traps, Chemical Control
CommunitySanitation, Public Education, Integrated Pest Management

Controlling vectors is important to prevent the spread of diseases. Some vectors can be easily controlled by individuals, like household pests through sanitation and exclusion. Some, however, like mosquitoes spreading malaria, require long-term, collective action, such as community clean-up programs, public education, and coordinated pest control efforts.

The Answer for Requirement Number 5b

During a visit to a food service facility, observing food preparation, handling, and storage is crucial to understand the measures taken to prevent contamination.

  1. Food Preparation: Workers often wear protective clothing, such as gloves and hairnets, to prevent direct contact with food. Surfaces and utensils are frequently cleaned and sanitized.
  2. Food Handling: The employees are trained to handle food correctly, which includes not touching ready-to-eat food with bare hands and using separate utensils for different food items to avoid cross-contamination.
  3. Food Storage: Proper storage is vital to prevent the growth of harmful bacteria. Cold foods are kept at temperatures below 40°F (4°C), and hot foods are kept at temperatures above 140°F (60°C). This range in-between is known as the “danger zone” where bacteria can multiply rapidly.

Microorganisms multiply rapidly under certain conditions such as warm temperatures, moisture, and the presence of nutrients, which are plentiful in food. Therefore, controlling the temperature and time that food is kept in the “danger zone” is crucial. This can be done by proper refrigeration, cooking food to the right temperature, and not leaving it at room temperature for too long.

A thermometer is essential to check food temperatures and ensure they are out of the “danger zone”. This can prevent bacterial growth and ensure that food is cooked to a safe temperature to kill any potential harmful bacteria.

This table summarizes the points:

TopicKey Points
Food PreparationUse of protective clothing, frequent cleaning and sanitization
Food HandlingProper training to avoid direct contact and cross-contamination
Food StorageControl of temperature to prevent bacterial growth
Conditions for Microorganism GrowthWarm temperatures, moisture, nutrients
Preventing Microorganism GrowthTemperature control, proper cooking and refrigeration
Importance of ThermometerEnsuring safe food temperatures, preventing bacterial growth

Remember to discuss your observations and the lessons learned with your counselor, including the practices that impressed you, and perhaps, areas where you think the facility could improve.
