- Infection is the invasion of an organism's body tissues by disease -causing agents, their multiplication, and the reaction of host tissues to the infectious agents and the toxins they produce.

Infection is the invasion of an organism's body tissues by disease-causing agents. The disease is caused by the invading agents multiplying. As they multiply, they produce toxins and damage host tissues. Infectious disease, also known as 'transmissible disease' or 'communicable disease', is illness resulting from an infection.

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. Some are transmitted by insects or other animals. And you may get others by consuming contaminated food or water or being exposed to organisms in the environment.Signs and symptoms var...
Each infectious disease has its own specific signs and symptoms. General signs and symptoms common to a number of infectious diseases include: 1. Fever 2. Diarrhea 3. Fatigue 4. Muscle aches 5. Coughing
Infectious diseases can be caused by: 1. Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis. 2. Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS. 3. Fungi. Many skin diseases, such as ringworm and athlete's foot, are caused by fungi. Other types of fungi can infect your lungs or nervous system. 4. Parasites. Malaria is caused by a tiny parasite that is t...
While anyone can catch infectious diseases, you may be more likely to get sick if your immune system isn't working properly. This may occur if: 1. You're taking steroids or other medications that suppress your immune system, such as anti-rejection drugs for a transplanted organ 2. You have HIV or AIDS 3. You have certain types of cancer or other disorders that affect your immune systemIn addition, certain other medical conditions may predispose you to infection, including implanted medical de...
Most infectious diseases have only minor complications. But some infections — such as pneumonia, AIDS and meningitis — can become life-threatening. A few types of infections have been linked to a long-term increased risk of cancer: 1. Human papillomavirus is linked to cervical cancer 2. Helicobacter pylori is linked to stomach cancer and peptic ulcers 3. Hepatitis B and C have been linked to liver cancerIn addition, some infectious diseases may become silent, only to appear again in the futur...
Follow these tips to decrease the risk of infection: 1. Wash your hands. This is especially important before and after preparing food, before eating, and after using the toilet. And try not to touch your eyes, nose or mouth with your hands, as that's a common way germs enter the body. 2. Get vaccinated. Vaccination can drastically reduce your chances of contracting many diseases. Make sure to keep up to date on your recommended vaccinations, as well as your children's. 3. Stay home when ill....
While the words \\"infectious\\" and \\"contagious\\" are often used interchangeably to describe illnesses, they actually mean two very different things.
Put simply, an infectious disease is a disease that can cause an infection. That is, when a microorganism comes into your body, and makes itself comfortable. For bacteria or fungi, this means dividing and growing new cells at an exponential rate.
Viruses, on the other hand, have an added hurdle of entering human cells and taking over their control centers so that they can make more of themselves. Regardless of the agent or mechanism, the effect is internal: pathogens come inside your body and spread throughout. Sometimes this can lead to symptoms. Sometimes it doesnt. The human papillomavirus is an example of a pathogen that can cause infection but not necessarily symptoms. Nearly all adults in the United States will get infected with HPV, but most don't even realize it. While the virus can lead to genital warts or cancer in some people, the vast majority of the time it doesn't cause any symptoms at all. Your body is able to clear the infection without you ever getting sickbut you could still spread it to others. A communicable disease is a contagious one. The effect is external. If someone catches the illness, they can get sick and spread the pathogenbe it a cold, virus, or some other disease-causing agentonto the next person. This can lead to small, isolated outbreaks or full-scale pandemics. Pathogens that go from one person to another can be transmitted a number of ways, such as through respiratory droplets like coughing or sneezing, sexual activity, contact with blood, or from mother to child during pregnancy, birth, or breastfeeding. While all communicable diseases are infectious, not all infections are communicable. Tetanus, for example, can cause an infection, but a person with tetanus can't spread it to other people.
An example of this happens each and every year in the United States from roughly October to May: the flu. As influenza viruses are passed from person to person and via contaminated objects, the virus spreads far and wide.
Active illness where you're sneezing or coughing a lot can give the microbe more opportunities to spread, but you don't have to have symptoms to be contagious. You don't even have to be around. Measles, for example, can be transmitted up to four days before you even develop the telltale rash, and the virus can stay in the air for as long as two hours after you have left the room.
