Respiratory diseases and meningitis are commonly acquired by contact with aerosolized droplets, spread by sneezing, coughing, talking, kissing or even singing.
Gastrointestinal diseases are often acquired by ingesting contaminated food and water.
Sexually transmitted diseases are acquired through contact with bodily fluids, generally as a result of sexual activity.
Some infectious agents may be spread as a result with contact with a contaminated, inanimate object, such as a coin passed from one person to another, while other diseases penetrate the skin directly.
Transmission of Infectious Diseases may also involve a vector. Vectors may be mechanical or biological. A mechanical vector picks up an infectious agent on the outside of it's body an transmits it in a passive manner. An example of a mechanical vector is a housefly, which lands on cow dung, contaminating it with appendages with bacteria from the feces, and then lands on food prior to consumption.
In contrast, biological vectors harbor pathogens within their bodies and deliver pathogens to new hosts in an active manner, usually a bite. Biological vectors are usually responsible for serious blood-borne diseases, such as malaria, viral encephalitis, Chagas disease, Lyme disease and African sleeping sickness. Biological vectors are usually arthropods, such as mosquitoes, ticks, fleas and lice.
Communicable diseases can be spread through direct contact with an infected person, such as by touching or shaking hands, through respiratory droplets when an infected person coughs or sneezes, by ingesting contaminated food or water, or through contact with contaminated surfaces or objects. Some communicable diseases can also be spread through vectors like mosquitoes or ticks.

What does non-communicable mean?
Non-communicable refers to diseases that are not transmitted from one person to another. These diseases are typically chronic in nature, such as heart disease, cancer, diabetes, and respiratory diseases. They are often caused by a combination of genetic, lifestyle, and environmental factors.
When a disease is spread by close contact between people it is considered a?
Communicable
How do diseases spread?
Diseases can spread through direct contact with infected individuals, such as touching or kissing, as well as through indirect contact by touching contaminated surfaces. They can also be transmitted through respiratory droplets from coughing or sneezing, as well as through contaminated food or water. Insects like mosquitoes can also transmit diseases through bites.
How are infrctious diseases spread?
Infectious diseases are spread through various means such as direct contact with an infected person, respiratory droplets when someone coughs or sneezes, ingesting contaminated food or water, or through vectors like mosquitoes or ticks. Some infectious diseases can also be spread through blood or bodily fluids.
How are noninfectious diseases caused?
Noninfectious diseases are caused by factors such as genetics, lifestyle choices (e.g. diet, exercise, smoking), environmental factors (e.g. pollution, radiation), and aging. These diseases develop over time and are not spread from person to person like infectious diseases. Examples of noninfectious diseases include heart disease, cancer, and diabetes.
What are communicable diseases and non communicable diseases?
Communicable: can be spread through a community (contagious) Non-Communicable: not spread with contact (usually genetic)
What do you mean by control of communicable disease?
The control of communicable diseases means that you are working to stop the spread of the disease. Communicable diseases can spread very quickly.

What is the difference between chronic diseases and communicable diseases?
Diseases are frequently referred to as communicable or non-communicable. 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. That leads to the term communicable.
What are communicable deseases?
Communicable diseases are ones that are easy to spread, like the flu. If you have the flu, you can spread it by coughing or even talking to a person.
Why are communicable diseases potentially more dangerous than non-communicable diseases in a community?
Communicable diseases can spread easily from person to person, leading to rapid outbreaks and higher infection rates in a community. This makes them potentially more dangerous as they can affect a larger number of individuals quickly. Non-communicable diseases, on the other hand, are typically chronic conditions that do not spread through direct contact.
What disease can pass from one organism to another?
There are Infectious Diseases and Non infectious Diseases. Infectious diseases can be transmitted from person to person, and can be spread from one living thing to another are known as communicable diseases. They can be caused by, Bacteria, Viruses, Protists, etc. which is the Plague. Non infectious diseases can not be transmitted from person to person, these are things like Cancers.
Describe three well known communicable diseases?
Communicable diseases spread from one person to another by pathogens. Three well-known communicable diseases are the common cold, strep throat, and HIV/AIDS.
What is the scope and significance communicable diseases?
Communicable diseases are illnesses that can be transmitted from person to person or from animals to people. They are significant because they can spread rapidly through populations, causing outbreaks and posing public health threats. Understanding and managing communicable diseases is crucial for preventing their spread and minimizing their impact on individuals and communities.
What causes communicable diseases?
Communicable diseases are diseases that are typically very dangerous and very contagious. Usually, diseases of this kind are spread by one person that catches the illness and unknowingly gives it to others.
