When someone sneezes into their hands and immediately offers to shake our own, most of us wince at the thought of accepting. It is more than merely revolting. That is one of many ways in which infectious diseases spread. Below, we'll examine several other ways in which germs are transmitted. Sometimes they're transferred from one person to another; other times, even a harmless-looking insect can be the culprit. By reviewing the list below, you can become more cautious of your environment and avoid infections along the way.
#1 - From Another Person
Colds, flus, and other viruses are typically passed along from another individual. At times, direct contact triggers the transfer (for example, while kissing, touching, or engaging in sexual activity). Other times, the bacteria can become airborne. A cough or sneeze can send millions of bacteria into the air. If you're within a closed space like a coffee shop, those bacteria may potentially land in your drink; once you take a sip, you can become infected.
#2 - From An Animal
Even though you might adore your dog or cat, they can transmit an infectious disease to you. If germs exist in their bodies, a scratch or bite can easily transfer them. Also, keep in mind that animals' waste matter can be another source of possible infection.
#3 - From Droplets Or Particles
When a person coughs or sneezes, the air is filled with germ-carrying droplets and particles. Both can contain infection-causing organisms such as those which lead to a cold. Droplets can travel for a few feet in the air before their weight carries them downward. If they enter your mouth or eyes, you can manifest symptoms quickly.
Particles are much smaller than droplets. Once expelled from an infected person, they can hang suspended in the air. Their weight is not sufficient to carry them downward. If you breathe them in, you can become infected and show signs similar to those of the original "owner" of the particles.
#4 - From Insects
A number of insects can also carry the germs that cause infectious diseases. For example, mosquitoes can carry the malaria virus and infect people through a bite. In some cases, direct exposure to the germs is not enough to infect a person. Instead, the biology of the insect is required by the organisms before they can infect another.
Avoid Catching Infectious Diseases
Your first line of defense is to wash your hands frequently. That alone can prevent the spread of bacteria. You should also avoid sharing items on which you place your mouth (for example, cups or toothbrushes). Unfortunately, there is little you can in public places to protect yourself from others' sneezes and coughs other than holding your breath, closing your eyes, and running outside. That said, by simply being aware regarding how bacteria and germs are transmitted, you'll be less vulnerable to infectious diseases in the future.
