Question

What is a communicable disease?

Answer 1

Communicable diseases are caused because of bacteria, viruses, or different pathogens and are transferable. In addition, we should understand that protozoal infection and AIDS are examples of such types of diseases.

Complete answer: Communicable diseases are those diseases that can unfold from one person to a unique associate degreed because an oversized variety of people urge sick. Spreading mostly occurs through bacteria or airborne viruses, but often through blood or other body fluids. To classify communicable diseases, the terminology infectious and contagious are often used. Infections may zero in severity from well (without symptoms) to severe and fatal. The term infection does not have an identity that suggests a disease as the results of some infections do not cause unhealthiness during a very host. They are caused by germs like being, viruses, fungi, parasites, or toxins. Germs which will cause communicable diseases square measure to unfold throughout a variety of the approach including:
Physical contact with an associate infected person, through contact with skin, (Staphylococcus aureus), sexual contact (Chlamydia, gonorrhea, syphilis), fecal/oral contact (rotavirus), or metabolism droplets (influenza, mumps). Contact with any contaminated surface or any contaminated object (norovirus), any type of food (Salmonella, E. coli), blood (HIV, liver disease B {viral liver disease} and hepatitis C), or water (cholera). Bites from insects or animals capable of passing the illness (West Nile River virus, zoonotic disease, and rabies); and through the air (tuberculosis and measles).

Note: Non-communicable diseases, unlike communicable diseases, are those diseases that are not transferable. Non-communicable disease (NCD) is a non-infectious or non-transmissible medical disorder or illness. Chronic disorders that last for long periods of time and progress steadily can be referred to by NCDs. This is caused by tissue deterioration, diet or hormone imbalance, and tumour development. Examples are diabetes, leukemia, etc.
