Communicable diseases are illnesses that can be transmitted from one person to another. Some of the examples include;
Gonorrhea
Tuberculosis
Malaria
Meningitis
Transmission is the passing of communicable diseases from an infected host individual or a con- specific (belonging to the same species) individual or group, regardless of whether the other individual was previously infected. MODES OF INFECTION

The main modes of infection are categorized into three;
Direct
Indirect
Airborne
1.DIRECT MODE OF INFECTION
DIRECT TRANSMISSION
By direct or immediate transfer of the agent to an appropriate portal of entry by personal contact, e.g. touching, biting, kissing, sexual intercourse By the direct projection of droplets onto the new host (through sneezing,coughing), but this must occur over a very short distance (1 meter or less) to be considered direct It is the spread of diseases from one infected host to a susceptible host.  Two categories:

i.Person to person transmission
ii.Animals transmission

PERSON TO PERSON TRANSMISSION
A.VENEREAL
1.SEXUAL CONTACT
Examples include;
Gonorrhoea
Genital warts
Chlamydia
Hepatitis B
Herpes
Trichomoniasis
2.THROUGH AIR
They are transmitted through aerosols.
 These are airborne particles with organisms in droplet form. Can also be spread by ventilation system. Examples include;
Tuberculosis
Measles
Chicken pox
Influenza
Mumps
Bacterial meningitis
3. FAECAL ORAL
This is the mode of transmission in which microorganisms are transmitted through contaminated water, food and objects Examples include;
a.Hepatitis A
b.Polio
c.Cholera
d.Rotavirus
e.Amoebiasis
f.Shigelosis
g.Giardiasis

4. FORMITES
Inanimate or substance capable of carrying infectious organisms such as germs or parasites hence transferring them from one individual to another. They are transmitted through skin cells, beddings, clothing, hair. Examples include ;

Fungal infections:-
Tinea verscolour,
Ring worms
B. ZOONOTIC
This is a mode of transmission where diseases spread from animals to
humans. Examples of zoonotic transmission include;
Animal bites
Example include;
Rabies
2. INDIRECT TRANSMISSION
Indirect transmission requires less intimate contact with the source. Two major types of indirect transmission are:
Vehicle-borne
Vector-borne
VEHICLE BORNE
For vehicle borne transmission, contaminated inanimate materials transfer the agent. These include fomites.
Fomites are objects such as clothes, bedding, eating utensils needles, surgical instruments, water. Examples of vehicle borne diseases:

TB,
cholera
 Samonellosis
 Tetanus
VECTOR BORNE
Vector borne transmission involves a living organism (besides a human). Vector borne transmission usually involves an arthropod. There are two general types of vector borne modes:
Mechanical
Biological
a)MECHANICAL VECTOR
For mechanical vector borne transmission, the organism is transmitted when it is carried on the vector’s body or passed through the vector’s gastrointestinal tract. The agent does not multiply or develop in the mechanical host. Examples of mechanical vector-borne diseases:

Diarrheal diseases
 TB
Polio
b)BIOLOGICAL VECTOR
With a biological vector, multiplication and/or some part of the agent’s development must occur in the vector before the agent can be transferred to humans. Examples of biological vector borne diseases:

Malaria,
Scabies,
Trypanosomiasis(sleeping sickness)
3. AIRBORNE TRANSMISSION
Transfer of an infectious agent via air over longer distances (greater than 1 meter). Results when the agent can remain suspended in the air for longer periods of time and/or over larger areas. Occurs when agents are suspended in either droplet nuclei (fluid) or attached to dust particles. Examples of airborne transmission:

Influenza
TB.
