- the air as small droplets (droplet spread) or tiny
aerosol particles (airborne spread)contact with
faeces (poo) and then with the mouth (faeco-oral spread)contact with the
skin or mucus membranes (the thin moist lining of many parts of the body toàn thân such as the nose, mouth, throat and genitals) (contact spread)blood or other body toàn thân fluids (for example, urine, saliva, breastmilk, semen and vaginal secretions).
Germs can spread:
- directly from person to person orindirectly from an infected person to the environment (for example toys, door
handles, bench tops, bedding and toilets) and then to another person who comes in contact with the contaminated environmental source.
Germs can enter the body toàn thân through the:
- mouthrespiratory tracteyesgenitalsbroken skin.
Some infections can be spread in several different ways.
There are other ways of describing how germs are spread that are commonly used. Germs can be spread through sexual contact, which is usually through semen and vaginal secretions (body toàn thân fluids), but can also occur through contact with mucus membranes. Germs can spread through food or water. Many but not all the germs spread in this way are through contact with faeces and then with the mouth (faeco-oral). Germs can also spread from a mother to her unborn child, usually though blood (body toàn thân fluids) but also through contact with skin or mucous membranes during delivery.

Spread through the air by droplets
Some infections are spread when an infected person talks, coughs or sneezes small droplets containing infectious agents into the air. Due to their size, these droplets in the air travel only a short distance (around a metre) from the infected person before falling. The droplets in the air may be breathed in by those nearby. Spread can also occur by touching the nose or mouth with droplet contaminated hands.
Examples of droplet spread diseases:
- common coldflumeningococcal diseaserubella.
Spread through the air by aerosol
Some infections are spread when an infected person talks, breathes, coughs or sneezes tiny particles containing infectious agents into the air. These are called small particle aerosols. Due to their tiny size, small particle aerosols can travel long distances on air currents and remain suspended in the air for minutes to hours. These small particle aerosols may be breathed in by another person.
Examples of airborne spread diseases:
- chickenpoxmeaslestuberculosis (TB)
Spread through faeces and then the mouth (faecal-oral spread)
Some infections are spread when microscopic amounts of faeces (poo) from an infected person with symptoms or an infected person without symptoms (a carrier) are taken in by another person by mouth. The faeces may be passed:
- directly from soiled hands to the mouthindirectly by way of objects, surfaces, food or water soiled with faeces.
Examples of diseases spread from faeces:
- Campylobacter infectionCryptosporidium infectionGiardia infectionhand, foot and mouth diseasehepatitis
A
meningitis (viral)rotavirus
infectionSalmonella infectionShigella infectionthrushviral gastroenteritiswormsYersinia infection.
Some infections are spread directly when skin or mucous membrane (the thin moist lining of many parts of the body toàn thân such as the nose, mouth, throat and genitals) comes into contact with the skin or mucous membrane of another person. Infections are spread indirectly when skin or mucous membrane comes in contact with contaminated objects or surfaces.
Examples of diseases spread by skin or mucous membrane contact:
- chickenpoxcold sores (herpes simplex infection)conjunctivitishand, foot and mouth diseasehead licemolluscum contagiosumringwormscabiesschool sores (impetigo)Staphylococcus aureus infectionwarts.
Spread through blood or other body toàn thân fluids
Some infections are spread when blood or other body toàn thân fluids (for example for example, urine, saliva, breastmilk, semen and vaginal secretions) from an infected person comes into contact with:
- the mucous membranes (the thin moist lining of many parts of the body toàn thân such as the nose, mouth, throat and genitals), such as through kissing, breast-feeding or sexual contact orthe bloodstream of an uninfected person, such as through a needle stick injury or a break in the skin.
Examples of diseases spread through blood or other body toàn thân fluids:
- hepatitis B - blood, saliva, semen and vaginal fluidshepatitis C - blood
human immunodeficiency virus (HIV) infection - blood, semen and vaginal fluids, breastmilkcytomegalovirus (CMV) infection - saliva, semen and vaginal fluids, urine, etc.glandular fever - saliva
Other ways of describing how infectious diseases are spread
Spread through sexual contact (sexually transmitted infections)
These infections are most commonly transmitted by sexual contact. Sexual contact means:
- genital to genitaloral to genitalgenital to anal.
Examples of sexually transmitted infections:
- Chlamydia infectiongenital herpesgenital wartsgonorrhoeahepatitis Bhuman immunodeficiency virus (HIV) infectionnon-specific urethritis (NSU)pubic
lice (crabs)syphilistrichomoniasis.
Spread through food or water
These diseases result from ingestion of water or a wide variety of foods contaminated with disease-causing germs or their toxins. Often these infections are also spread by the faecal-oral route.
Examples of food or waterborne diseases:
- botulismCampylobacter infectioncholeraCryptosporidium infectionhaemolytic uraemic syndromeListeria infectionSalmonella infectionShigella infectiontyphoid
and paratyphoidYersinia infection.
Spread from a mother to her unborn child
Some infections can be spread through the placenta from a mother to her unborn child or during delivery, or both.
Examples of diseases spread from a mother to child in this way:
- chickenpoxcongenital cytomegalovirushepatitis Brubella.
Diseases where person-to-person spread occurs rarely, if ever
Some infectious diseases are almost never spread by contact with an infected person. These diseases are usually spread by contact with an environmental source such as animals, insects, water or soil.
Examples of diseases spread by contact with animals:
- cat-scratch diseasehydatid diseasepsittacosisQ feverrabiestoxoplasmosis.
Examples of diseases spread by insects, and in the examples listed below, specifically by mosquitoes:
- Barmah Forest virus infectiondengue
fevermalariaRoss River virus
infection.
Examples of diseases spread by contact with water or soil:
- amoebic meningitislegionella infection -
Legionella pneumophila and
Legionella longbeachaetetanus.

Food- or water-borne illnesses are not spread from casual contact with another person. A person can come into contact with food- or water-borne bacteria by eating or drinking something that has bacteria in it.How do germs get spread?
Germs can spread from one person to another through direct contact when people shake hands, hug, or kiss. Germs can also spread through indirect contact if people touch something with germs already on it, like a doorknob, and then touch their eyes, nose, or mouth.What is the most common way bacteria spread food?
The main way that contamination spreads in the kitchen is by our hands. Too often, people don't wash their hands before making food. And people often don't wash their hands between handling possibly contaminated foods such as meat and other foods that are less likely to be contaminated, such as vegetables.How fast does germs spread on food?
Germs immediately attach to food dropped on the floor. They don't have to wait five seconds to do anything. Germs are very sticky creatures; as soon as your food touches the floor, the germs stick, according to research done by P. Dawson as reported in the Journal of Applied Microbiology.
