Viruses are responsible for many infections, such as the flu, the common cold, conjunctivitis (pink eye), and coronavirus. With the coronavirus (COVID-19) pandemic in full swing, it's important to be aware of good hygiene practices, especially for the eyes, as they are a portal for infectious diseases. By implementing the practices below, you can significantly reduce the risk of contracting or transmitting a viral infection.
A virus is a submicroscopic infectious agent that reproduces itself by invading a host cell, replicating its genetic material (DNA or RNA) inside it. This infected cell then replicates rapidly, spreading millions of new viral cells throughout the body. Once infected, we feel sick and experience the unpleasant side effects of rising temperature, sore limbs, and other symptoms as our immune system recognizes the virus as being foreign and vigorously fights against it.
For a virus to cause disease, it must first enter a body, called a target host. A target host can get infected directly, via infected droplets (such as when kissing), or indirectly, when coming into contact with droplets from a cough, sneeze, or tears left on a surface. Infected droplets enter the body through one of the mucous membranes, such as the eyes, nose, or mouth.
Even if the infected person shows no symptoms, they can still be contagious. Depending on the virus, it can survive on a surface for some time and can be picked up from a doorknob or an elevator button. This is why practising good hygiene is an effective way to prevent indirect viral transmission.
By implementing the following hygiene practices, you will better protect yourself and others from viral infection.
We, humans, touch many surfaces throughout the day. If we're not careful, we can catch an infection, particularly from hard surfaces like plastic and stainless steel.
Viruses can also be picked up while preparing and eating food, using the toilet, or handling an animal. Make sure that you regularly and thoroughly wash your hands, ideally for a minimum of 20 seconds with soap and water, to kill viruses (and bacteria) on the surface of your skin. If soap and water aren’t available, use an alcohol-based hand sanitiser.
Studies show that the average person touches their face up to 23 times per hour, and that the majority of contacts involve the eyes, nose, and mouth. Doing so puts you at risk for getting a virus or transmitting the virus to another person. Try to be conscious and avoid touching your face whenever possible.
Rubbing your eyes is an instinctual response to tiredness or itchy eyes. It feels great to rub your eyes because doing so stimulates tear production, temporarily relieves itchiness, lubricates the eyes, and removes irritants. However, if your hands are unwashed, rubbing your eyes can put you at risk of contracting an infection, such as conjunctivitis or coronavirus. In fact, conjunctivitis has been linked to respiratory infections like the common cold, the flu, and COVID-19.
Given the information provided above regarding infections, the following advice should come as no surprise:
