What Is Public Health?
Public Health is defined as “the art and science of preventing disease, prolonging life and promoting health through the organized efforts of society”. Public health promotes and protects the health of people and the communities where they live, learn, work and play.
It is the science of protecting and improving the health of people and their communities. This work is achieved by promoting healthy lifestyles, researching disease and injury prevention, and detecting, preventing and responding to infectious diseases. Overall, public health is concerned with protecting the health of entire populations. These populations can be as small as a local neighborhood, or as big as an entire country or region of the world.
E. coli (Escherichia coli), is a type of bacteria that normally lives in your intestines. It’s also found in the gut of some animals. Most types of E. coli are harmless and even help keep your digestive tract healthy.
You can get E Coli from under-cooked ground beef, untreated milk, contaminated fruits and vegetables, and other foods. It can also be contracted from drinking contaminated water or coming in contact with animals.
You can prevent it with good hygiene when handling foods, cooking ground beef to recommended temperature, washing produce, avoiding swallowing water when swimming, and other simple practices.
Tetanus is a serious disease of the nervous system caused by a toxin-producing bacterium. When the dormant bacteria enter a wound the cells are “awakened.” As they are growing and dividing, they release a toxin which impairs the nerves in the body that control muscles.
You can prevent tetanus by being vaccinated.
Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). It can spread through sexual contact, illicit injection drug use or sharing needles, contact with infected blood, or from mother to child during pregnancy, childbirth or breastfeeding.
You can prevent AIDS by avoiding sexual contact and not using illegal drugs.
Encephalitis is an inflammation of the brain, most often caused by a viral infection.
It can be prevented with the usual measures to avoid viruses, such as good hygiene and not sharing utensils. It can also be spread by mosquitos and ticks, so wearing long pants and long sleeved shirts outdoors and applying insect repellent are also good measures. Also, do not have standing water in your yard, since this is where mosquitos breed.
Salmonella is the type of bacteria that’s the most frequently reported cause of food-related illness in the United States. It causes Salmonellosis. You can contract it from eating under-cooked meat or eggs, contaminated fruits and vegetables, unpasteurized dairy products, and contaminated processed foods. It can also be contracted directly through poor hand hygiene and from pets.
You can prevent Salmonella by cooking meats and eggs, washing raw produce, refrigerating food properly, good hygiene, and avoiding cross contamination when preparing food.
Lyme disease is a bacterial infection you get from the bite of an infected tick.
You can prevent Lyme disease by wearing long pants and long sleeved shirt when hiking, applying insect repellent, keeping your yard mowed and free of brush, and checking yourself for ticks after being outdoors.
COVID-19 is caused by a virus which is primarily transmitted via respiratory droplets. It spreads easily.
You can prevent COVID-19 or lessen its severity by being vaccinated. Other recommended measures include avoiding close contact with anyone who is sick or has symptoms, social distancing, avoiding crowded indoor spaces, practicing good hygiene, and wearing a face mask in indoor settings.
Gonorrhea is a sexually transmitted disease which is caused by a bacterial infection.
You can prevent gonorrhea by avoiding sexual contact.
West Nile virus is spread to people through the bite of an infected mosquito.
It can be prevented by wearing long pants and long sleeved shirts outdoors and applying insect repellent. Also, do not have standing water in your yard, since this is where mosquitos breed.
Botulism is a serious illness that affects the nervous system. It occurs when poisonous substances called botulinum toxins produce skeletal muscle paralysis. The most common type is food botulism.
It can be prevented by refrigerating foods within two hours of cooking, cooking food thoroughly, and avoiding food from cans which are damaged are bulging. Also, infants under the age of 1 year old should not be given honey.
Influenza — also known as the flu — is a contagious viral infection that attacks your respiratory system.
It can be prevented by washing hands, avoiding crowds during an outbreak, covering your mouth and nose when you sneeze or cough, and avoiding contact with others if you have a fever
Syphilis is a sexually transmitted infection caused by a type of bacteria.
You can prevent syphilis by avoiding sexual contact.
Hepatitis is the inflammation of the liver. Hepatitis can be caused by drugs, alcohol or other toxins, by infection with bacteria, viruses or parasites. The primary sources of the hepatitis A and E viruses are raw or under-cooked food, food handled by people who have not properly washed their hands and water contaminated by animal or human waste. Hepatitis C is mainly spread through contact with the blood of an infected person.
Vaccines are available for some strains of hepatitis. Cooking food properly, good hygiene, and avoid blood contamination also prevent the disease.
Emphysema is a lung condition that causes shortness of breath. The primary cause of Emphysema is exposure to airborne irritants from tobacco or marijuana smoke, air pollution, or chemical fumes.
Since smoking causes most cases of emphysema, the best way to prevent it is to not smoke and to avoid second hand smoke.
Meningitis is an inflammation of the fluid and membranes (meninges) surrounding your brain and spinal cord. Viral and bacterial infections are the most common causes of meningitis.
Meningitis can be prevented with hand washing, good hygiene, healthy diet and habits, and covering your mouth when you cough or sneeze. Vaccinations are available for some forms of bacterial meningitis.
The herpes simplex virus, also known as HSV, is a viral infection that causes genital and oral herpes. It can be spread through saliva, genital contact, and through contact with other areas of the skin and the eyes.
It can be prevented by avoiding sexual contact and avoiding contact with a person who is experiencing an outbreak.
Lead poisoning occurs when lead builds up in the body, often over months or years. Lead-based paint and lead-contaminated dust in older buildings are common sources of lead poisoning in children. Other sources include contaminated air, water and soil.
Lead poisoning can be prevented by reducing exposure to lead. This includes washing hands after playing outdoors, cleaning dusty surfaces, removing shoes in the house, running cold water before using, eating a healthy diet, and removing lead based paint.
