Biological hazards, also known as biohazards, refer to biological substances that pose a threat to the health of living organisms, primarily that of humans. This can include samples of a microorganism, virus or toxin (from a biological source) that can affect human health. It can also include substances harmful to other animals.
Biological Hazards
Sources of biological hazards may include bacteria, viruses, insects, plants, birds, animals, and humans. These sources can cause a variety of health effects ranging from skin irritation and allergies to infections (e.g., tuberculosis, AIDS), cancer and so on.
Acquired Immune Deficiency Syndrome
Acquired Immune Deficiency Syndrome (AIDS) is a virus that slowly destroys the body's immune system, leaving it vulnerable to a hos of illnesses, eventually causing death, as there is presently no cure for AIDS.
Anthrax
This is an infectious disease caused by a bacterium, called Bacillus, that produces a spore which can cause infections of the lungs. It can also affect the skin, mouth, throat, and part of the digestive system. Usually it is acquired via inhalation or eating contaminated undercooked food (usually meat).
Hepatitis
This refers to an infection of the liver. There are various types of hepatitis, referred to as A, B, C, D, E. Some are caused by infections, some by a specific virus. It can be spread from human to human via bodily fluids. Immunization exists for A and B, but not for the others. Some forms clear on their own after a few weeks, while others, in some cases, may cause death or at least severe illness.
Influenza
Not to be confused with the common cold, which is much less seriously, influenza, also known as the flu, is a virus that affects the respiratory track (throat, lungs, nose, mouth, etc). The elderly, and people with other health problems, are much more susceptible to complications. In some cases it can cause death. Immunization exists for influenza, which seems to get worse in the winter, but it changes regularly so the medical profession is always working to keep up with the different forms.
The Common Cold
Also caused by a virus, but much less severe than influenza. It is very difficult to distinguish from the flu, so if symptoms persist medical attention should be sought, especially for susceptible groups (e.g. elderly and really young).
Lyme Disease
A bacterium that is spread by ticks, which is spread to the host (e.g. rodents, pets, humans, etc). It can cause flu-like symptoms, as well as arthritis, and cardiac irregularities. This is of particular concern for outdoor workers inn areas where there are a lot of trees/plants and wild animals. Other symptoms: rashes, extreme fatigue, sore joints, headaches, fever, etc.
Rabies:
A very serious virus, that infects and destroys brain tissue, that will lead to death if medical attention isn't obtained quickly. Anyone suspecting of coming in contact with an infection must seek medical help immediately (vaccination), before warning signs appear. Once warning signs appear it is almost always to late to save that person. It is contracted by exposure to bodily fluids from any warm-blooded animal, even a scratch from an infected cat or dog, or droplets enter into the eyes or nose.
Tuberculosis
An infection of the lungs caused by a bacteria called Mycolbacterium Tuberculosis, which infects the lungs. Weight loss, fatigue, fever, and coughing are warning signs. Treatment exists and is usually very successful. Many times treatment is not needed as the person's immune system can handle the infections. But precautions should be taken not to transmit the disease.
