What do infectious and noninfectious diseases have in common?
Students should recognize that infectious diseases are caused by pathogens such as viruses, bacteria, and parasites and can be spread by direct contact or through vectors. Noninfectious diseases cannot be “caught” from other humans or animals.
What do infectious diseases have in common?
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 is the relationship between an infectious disease and a contagious disease?
Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. 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.
What are non-infectious diseases give two examples of non-infectious diseases?
Examples of noninfectious diseases include cystic fibrosis, most cancers, cardiovascular diseases such as coronary artery disease, and diabetes mellitus.
Who most common infectious diseases?
The 5 Most Common Infectious Diseases
- Hepatitis B. According to current statistics, hepatitis B is the most common infectious disease in the world, affecting some 2 billion people — that’s more than one-quarter of the world’s population.
- Hepatitis C.
What is the difference between 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.
What are the three main ways infectious diseases are spread?
Germs can spread from person to person through:
- the air as droplets or aerosol particles.
- faecal-oral spread.
- blood or other body fluids.
- skin or mucous membrane contact.
- sexual contact.
Which disease is non-infectious?
Non-infectious diseases are not caused by pathogens and therefore cannot be spread from one person to another. Instead, non-infectious diseases are caused by factors such as genetics, malnutrition, environment and lifestyle. Examples of non-infectious diseases include cancer, Alzheimer’s disease and epilepsy.
What are the 10 non communicable diseases?
Some common noncommunicable cardiovascular conditions and diseases include:
- heart attack.
- coronary artery disease.
- cerebrovascular disease.
- peripheral artery disease (PAD)
- congenital heart disease.
- deep vein thrombosis and pulmonary embolism.
What is the most deadly infectious disease?
TB is currently the deadliest infectious disease, responsible for 1.6 million deaths last year, most of them in the developing world. And that’s not the scariest part. A rapidly growing number of patients are developing drug-resistant tuberculosis, which kills more people than any other drug-resistant pathogen.
What is the difference between infectious and chronic diseases?
An infectious disease is a disease caused by a biological agent such as a virus, bacteria, fungus, protozoa or parasite. A chronic disease is a disease that has persisted for a prolonged time such as kidney failure on dialysis, diabetes, COPD .
What is the most communicable disease?
The top five most contagious infectious diseases include respiratory tract infections such as bronchitis and pneumonia, HIV/AIDS, diarrheal diseases, tuberculosis and malaria. Respiratory tract infections, especially lower respiratory infections such as bronchitis and pneumonia are considered the most contagious and deadly.
What are some examples of non communicable diseases?
Examples of non-communicable diseases include diabetes, Alzheimer’s, cancer, osteoporosis, chronic lung disease, stroke, and heart disease. Almost four-fifths of all deaths from non-communicable diseases occur in developing countries. Non-communicable diseases, also known as NCDs are non-infectious medical diseases or conditions.
