Also, visit our coronavirus hub for more information on how to prepare, advice on prevention and treatment, and expert recommendations. Airborne disease can spread when people with certain infections cough, sneeze, or talk, spewing nasal and throat secretions into the air. Some viruses or bacteria take flight and hang in the air or land on other people or surfaces.
These infectious microscopic organisms are known as pathogens, and they can multiply quickly. Examples of pathogens include:. They can spread in several different ways, including through:.
Foodborne illness is caused by consuming contaminated foods or beverages. Many different disease-causing microbes or pathogens can contaminate foods, so there are many different types of foodborne illnesses. Most foodborne diseases are infections caused by a variety of bacteria, viruses, and parasites. Other diseases are poisonings caused by harmful toxins or chemicals that have contaminated food. Of note many foodborne pathogens also can be acquired through recreational or drinking water, from contact with animals or their environment, or through person-to-person spread. Please report your suspected foodborne illness to the Minnesota Department of Health.

Airborne disease can spread when people with certain infections cough, sneeze, or talk, spewing nasal and throat secretions into the air. Some viruses or bacteria take flight and hang in the air or land on other people or surfaces. When you breathe in airborne pathogenic organisms, they take up residence inside you. You can also pick up germs when you touch a surface that harbors them, and then touch your own eyes, nose, or mouth.
A communicable disease is a disease that spreads from one person or animal to another. Pathogens such as viruses, bacteria, and fungi cause these diseases. A communicable disease is any disease that passes between people or animals. A person may develop a communicable disease after becoming infected by the pathogen. This may happen through:.
Jump to navigation. People with allergies have especially sensitive immune systems that react when they contact allergens. Because there are so many possible causes, the symptoms of allergies vary widely. Airborne allergens, like pollen and pet dander, are likely to cause:. In cases of a more extreme response, called anaphylaxis, symptoms are severe and life-threatening.

Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful. But under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person.
Disease , any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury. A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state. Thus, the normal condition of an organism must be understood in order to recognize the hallmarks of disease. Nevertheless, a sharp demarcation between disease and health is not always apparent.
Waterborne diseases are conditions caused by pathogenic micro-organisms that are transmitted in water. These diseases can be spread while bathing, washing, drinking water, or by eating food exposed to contaminated water. While diarrhea and vomiting are the most commonly reported symptoms of waterborne illness, other symptoms can include skin, ear, respiratory, or eye problems. Microorganisms causing diseases that characteristically are waterborne prominently include protozoa and bacteria , many of which are intestinal parasites , or invade the tissues or circulatory system through walls of the digestive tract.
