What is a Communicable Disease?
Communicable diseases are those which can spread from one person to another through direct or indirect contact. Direct transmission of communicable diseases takes place via blood, faeces, saliva, and other fluids of the body. Indirectly, such diseases spread through air, water, food, and insects.
Communicable diseases are also known as acute, as their symptoms develop quickly. Once the agents of such diseases enter the body, the immune system tries to destroy them. However, when the organism escapes the immune system, the disease appears.
Communicable diseases are known to occur during a specific period or time of the year. For instance, malaria spreads during the breeding season of the female mosquitoes. Let us see the top 10 communicable diseases:

Ways to Prevent Communicable Diseases
The best way to prevent communicable diseases is to wash your hands frequently. Washing your hands removes a lot of viruses and keeps you safe.
Avoid going to public places when you are not well. Since communicable diseases can spread through fluid or atmosphere, staying indoors is a great way to prevent the diseases from spreading to others.
Cover the nose and mouth while sneezing and coughing with tissue. Alternatively, you can sneeze in the elbow or upper sleeves but not the hands.
If you are unwell, avoid sharing personal belongings like towels, razors, etc, as they cannot be disinfected.
When preparing food, take utmost care to wash the hands, utensils, and surfaces thoroughly.
Get yourself vaccinated against diseases like coronavirus, flu, and so on.
Indulge in safe sex practice by using condoms to reduce the risk of sexually transmitted diseases.
What is a Non-Communicable Disease?
Non-communicable diseases are not contagious, meaning they do not spread from one person to another through any medium. Causes of non-communicable diseases include many factors like poor lifestyle, bad eating habits, environmental factors, heredity, and so on.
Non-communicable diseases are also called chronic because they slowly develop over time. They are long-term in nature and can be caused by a lack of nutrients in the body, consumption of alcohol, tobacco, and other factors.
Non-communicable diseases affect people of all ages, groups, and regions. Most of the time, these diseases are associated with higher age groups, but according to evidence, 17 million non-communicable disease-related deaths happen before the age of 70 years.
