5 Common Ways Germs are Spread

  • Nose, mouth, or eyes to hands to others: Germs can spread to the hands by sneezing, coughing, or rubbing the eyes and then can be transferred to other family members or friends.
  • Hands to food:
  • Food to hands to food:
  • Infected child to hands to other children:
  • Animals to people:

How are viruses and bacteria transmitted?

Bacteria and viruses can travel through the air, causing and worsening diseases. They get into the air easily. When someone sneezes or coughs, tiny water or mucous droplets filled with viruses or bacteria scatter in the air or end up in the hands where they spread on surfaces like doorknobs.

How are viruses contracted?

Viruses can be transmitted in a variety of ways. Some viruses can spread through touch, saliva, or even the air. Other viruses can be transmitted through sexual contact or by sharing contaminated needles. Insects including ticks and mosquitoes can act as “vectors,” transmitting a virus from one host to another.

How are bacterial diseases contracted?

Bacteria are transmitted to humans through air, water, food, or living vectors. The principal modes of transmission of bacterial infection are contact, airborne, droplet, vectors, and vehicular.

How do viral infections spread directly?

Some infections are spread directly when skin or mucous membrane (the thin lining of parts of the body such as nose, mouth, genitals) comes into contact with the skin or mucous membrane of an infected person. Infections may be spread indirectly when the skin comes in contact with a contaminated object.

How do virus spread from person to person?

Person-to-Person Transmission There are several ways this can happen: Droplets or aerosols. This is the most common transmission. When an infected person coughs, sneezes, or talks, droplets or tiny particles called aerosols carry the virus into the air from their nose or mouth.

Is bacteria or virus more contagious?

Viral Infections Are more contagious than bacterial infections. (If more than one person in the family has the same illness, odds are it is a viral infection.) Can make you just as sick as bacterial infections. Usually get better in 4-5 days but it might take as long as three weeks to fully recover.

Can a bacterium be infected by a virus?

Yes. These viruses are called bacteriophages and they are extremely common. Around a quarter of the bacteria in the sea at any one time are infected by bacteriophages and they are so successful that the viruses often outnumber bacteria by a factor of 10.

How does a virus spread from person to person?

The virus spreads easily between people. How easily a virus spreads from person-to-person can vary. Some viruses are highly contagious, like measles, while other viruses do not spread as easily. Another factor is whether the spread is sustained, which means it goes from person-to-person without stopping.

Can a bacterial infection cause diarrhea or a virus?

In some cases, it may be difficult to determine whether a bacterium or a virus is causing your symptoms. Many ailments — such as pneumonia, meningitis and diarrhea — can be caused by either bacteria or viruses.

How does germs get from person to person?

Inhalation occurs when germs are aerosolized in tiny particles that survive on air currents over great distances and time and reach a susceptible person.
