✔✔Communicable diseases are the diseases which passes from one individual to another individual.
They are generally caused by some bacteria, viruses or any other pathogens. For example, malaria, AIDS
etc. Non-communicable diseases are the diseases which does not spread from one person to another
person.
Disease transmission: How are these diseases spread? How can we break the chain of infection (how can
we stop the spread?)
Tuberculosis (TB) - correct answer ✔✔Tuberculosis (TB) is a disease caused by bacteria called
Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts
of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes, or
talks. Can be prevented through early detection and isolation and quarantine of infected people.
Rabies - correct answer ✔✔an acute viral infection that is most commonly transmitted to humans by the
bite or saliva of an infected animal. Prevention of rabies can be vaccinating animals
Zika virus - correct answer ✔✔Aedes mosquito, possible sexual, vertical transmission, methods such as
using bug spray, long sleeves, pest control can prevent spread of virus.
Human Immunodeficiency Virus (HIV) - correct answer ✔✔Acquired immunodeficiency syndrome (AIDS)
is caused by HIV, which damages the cells in the body's immune system so that the body is unable to
fight infection or certain cancers. Prevention is through safe sex measures such as condoms, abstinence,
etc.
Ebola - correct answer ✔✔A contagious viral disease originating in Africa caused by bats or other wild
animals, It is transmitted by blood and body fluids and causes body organs and vessels to leak blood,
usually resulting in death. Preventative measures include washing hand, be notified of certain areas, stay
away from meat products if in area where it is prominent.
Means of Transmission - correct answer ✔✔Infectious diseases are spread by a variety of routes, directly
from one person to another or indirectly by way of water, food, or vectors such as insects and animals.
