EMPLOY STRATEGIES OF DISEASE PREVENTION IN PREVENTING AND CONTROLLING COMMUNICABLE DISEASE IN THE COMMUNITY

Describe communicable disease

Identify risk factors of communicable disease

Identify potential contamination of water source

Undertake immunization

Educate community on food safety

Ensure safe injection

Identify sources of vector

Communicable disease; is an illness caused by infectious agents or pathogens that can spread directly from one person to another, typically through respiratory droplets, body fluids of contact with contaminated surfaces.

Examples influenza(flu), tuberculosis(TB), covid-19, HIV/AIDS, hepatitis, cholera, malaria, measles, sexual transmitted infections(STIs).

All of above diseases if not treated early may lead to life threatening complication.

The risk may vary depending on the specific disease. The following are some common factors

Close contact with infected individuals.

Poor hygiene practices. Eg not washing hands frequently, not covering cough or sneezes

Crowded or unsanitary living conditions. Eg living environment with poor sanitation ca facilitate spread of disease

Travel to areas with high diseases prevalence.

Weakened immune system.

Lack of vaccination.

Unsafe sexual practices.

Exposure to contaminated food or water.

Inadequate access to healthcare.

Water source can become contaminated by various means, leading to potential health risks for those who consume or come into contact with the contaminated water.

Some common causes of water contamination include

Microbial pathogens; bacteria, viruses, and parasites from human or animal waste can contaminate water sources, leading to diseases such as cholera, typhoid fever and giardiasis.

Chemical pollutants; industrial runoff, agriculture pesticides and fertilizers, may introduce chemical to water sources posing risks of human health.

Sediment and suspended solids; soil erosion, construction activities, and urban runoff can introduce sediment and suspended solids into water sources affecting water quality and aquatic habitats

Nutrient pollution; excess nutrients from fertilizers, sewage, and animal waste can lead to algal blooms and depletion of oxygen in water bodies, which can harm aquatic life and human health.

Toxic algae; certain species of algae can produce toxins that contaminate water sources during algal blooms, leading to health problems such as skin irritation, respiratory issues.

Heavy metals; industrial activities, mining operations and natural sources can introduce heavy metals such as leading arsenic and cadmium into water sources, posing serious health risks, and cancer.

Radionuclides; natural occurring radioactive elements such as radium and uranium can contaminate water sources posing serious health risk.

Emerging contaminants; include substance such as pharmaceuticals, personal care products and microplastics which can enter sources through various routes and cause health effects,

Involves receiving vaccines to protect against various infectious disease. Vaccines stimulate the immune system to produce an immune response without causing the disease itself.

This helps body to develop immunity to specific pathogens, preventing illness and reducing the spread of communicable disease.

Immunization is critical public health intervention that not only protects individuals from serious disease but also contributes to community immunity or herd immunity.

Immunization schedules vary nby country and may include vaccines against diseases such as measles, mumps, rubella, pollion, influenza, hepatitis B, pneumococcal disease, and human papilomavirus(HPV).

Educating the community on food safety is crucial for preventing foodborne illnesses and promoting public health

Educate community on

Proper food handling

Safe food storage

Cooking temperature

Avoiding high-risk foods

Hand hygiene

Awareness of food recalls

Symptoms of food borne illness

Safe food preparation practices

Cleaning and sanitizing

Personal hygiene

Use sterile equipment

Proper needle disposal

Hand hygiene

Clean injection site

Safe medication handling

Proper injection technique

Single-dose vials and ampules

Avoiding needle recapping

Education and training

Monitoring and auditing

Vectors are organisms that transmit pathogens from one host to another, thereby spreading infectious diseases. Common sources of vectors include;

Mosquitoes; transmitting disease such as malaria, dengue fever, zika virus.

Ticks; transmiting variety pathogens including lyme disease,tick borne encephalitis

Fleas; transmit disease such plague

Sendflies; transmit leishmaniasis

Tsetse flies; transmit african trypanasomiasis(sleeping sickness)

Triatomine bugs; transmit trypanasoma cruzi

Blackflies; transmit onnchocerciasis( river blindness)

Rodents; transmit plague, leptospirosis
