As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren’t effective against viruses..

What are some illnesses caused by bacteria?
Illnesses caused by infectious bacteria include:
- Strep throat.
- Food poisoning.
- Urinary tract infection.
- Skin infections.
- Toxic shock syndrome.
What is the name of infectious disease?
List
| Infectious agent | Common name | Vaccine(s) |
|---|---|---|
| Trypanosoma cruzi | Chagas disease (American trypanosomiasis) | Under research |
| Haemophilus ducreyi | Chancroid | No |
| Varicella zoster virus (VZV) | Chickenpox | Yes |
| Alphavirus | Chikungunya | Under research |
Which disease is caused by parasite?
Examples of parasitic diseases that can be bloodborne include African trypanosomiasis, babesiosis, Chagas disease, leishmaniasis, malaria, and toxoplasmosis.
How do viruses cause illness?
Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood.
What’s parasitic infection?
Parasites are organisms that live in or on another organism, called the host. The parasites can be microscopic or large enough to see with the naked eye, and they survive by feeding from the host. They can also spread parasitic infections, which can lead to sepsis.
What is the infection?
(in-FEK-shun) The invasion and growth of germs in the body. The germs may be bacteria, viruses, yeast, fungi, or other microorganisms. Infections can begin anywhere in the body and may spread all through it. An infection can cause fever and other health problems, depending on where it occurs in the body.
What causes parasites in humans?
Anyone can contract a parasitic infection and some people are at higher risk because of certain reasons. One of the most common ways of contracting this type of condition is through contaminated food such as undercooked meat or drinking unclean water.
What causes disease? 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.
What are infectious diseases also known as?
Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
What is communicable and noncommunicable disease?
Communicable diseases comprise infectious diseases such as tuberculosis and measles, while non-communicable diseases (NCDs) are mostly chronic diseases such as cardiovascular diseases, cancers, and diabetes.
Why are infectious diseases called communicable diseases?
Infectious disease is caused by certain microorganisms called pathogens and leads to infections. These can be spread from one person to another hence are also called communicable disease.
What causes communicable disease?
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. Communicable diseases can transmit through contact with bodily fluids, insect bites, contaminated surfaces, water, and foods, or through the air.
What causes infection?
Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease, which typically happens in a small proportion of infected people, occurs when the cells in your body are damaged as a result of infection, and signs and symptoms of an illness appear.
What is viral disease? Viral diseases are infections caused by viruses. Different types of viruses cause different infections. Common cold is the most common type of viral infection that is caused by infections in the respiratory tract. Other viral diseases include: Chickenpox.
What are infectious and noninfectious diseases? Infectious diseases are transmitted from person-to-person through the transfer of a pathogen such as bacteria, viruses, fungi or parasites. A non-infectious disease cannot be transmitted through a pathogen and is caused by a variety of other circumstantial factors.
Are all diseases communicable? Some — but not all — infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious. Some infections spread to people from an animal or insect, but are not contagious from another human.
What is type of infectious disease?
Prevalent parasitic infections include malaria, Chagas disease, and toxocariasis. Viral infections– like bacteria, viruses can cause many different infectious diseases. The common cold develops from a virus, as does more complex diseases like the flu, mononucleosis, smallpox, and HIV/AIDS.
What causes illness?
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.
What is viral infection?
A viral infection is a proliferation of a harmful virus inside your body. Viruses cannot reproduce without the assistance of a host. Viruses infect a host by introducing their genetic material into the cells and hijacking the cell’s internal machinery to make more virus particles.
What causes viral infection?
Coughing and sneezing. Contact with infected people, especially through kissing and sex. Contact with contaminated surfaces, food, and water. Contact with infected creatures, including pets, livestock, and insects such as fleas and ticks.
What is causative pathogen?
Causative agents in infection are pathogens. Pathogens are micro-organisms that are capable of causing diseases or infections. If micro-organisms from a person’s own body cause an infection, it is called an endogenous infection.
What are the names of infection?
Some examples of bacterial infections are:
- bacterial meningitis.
- otitis media.
- pneumonia.
- tuberculosis.
- upper respiratory tract infection (although this is usually viral)
- gastritis.
- food poisoning.
- eye infections.
What causes illness?
The presence of diseases – Usually, illness occurs because the body has an underlying disease. The body is designed to provide a natural response to any abnormality or threat, whether it’s a bacterium, virus, or excessive production of immature cells. But in the process, such reaction can make a person feel sick.
What is disease and types of disease? There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.
What are examples of communicable diseases?
