What are the main causes of the spread of illnesses?

It’s normal for our bodies to be susceptible to infectious diseases occasionally. Some of us may develop symptoms and react to these diseases, while others may not (asymptomatic). However, if you ever wondered what causes the spread of most of these infections, this article will walk you through it.

Infectious diseases can be contagious and result from bacteria, fungi, viruses, and other forms of organisms. These organisms may be effective and harmless, but in some cases can lead to the risk of disease. 

Exposure to the environment is enough for you to acquire a virus, while contaminated water or food are other reasons that expose you to greater risks.


Bacteria, Viruses, Fungi, and Parasites are all types of organisms that act as the primary underlying cause for skin diseases, tuberculosis, common colds, AIDS, and now recently, COVID-19. Here are common mistakes we make that lead to us acquiring the illness.

Direct Contact

The easiest way you can catch a virus is to come in direct contact with another person or animal carrying the same infection. Eventually, the infection spreads to you.

Person to person infections are the most common and give rise to the spread of seasonal illnesses like influenza and COVID-19. Bacteria and germs are present in the environment, and people transmit them from one another.

The person carrying the disease may even be unaware of it as they may be asymptomatic while simply acting as a carrier of the disease.

Indirect Contact

Inanimate objects may also be carriers of infectious organisms. Infections can easily transmit to a person who encounters an object carrying the organism.

If a sick person touches a surface and you touch it later, the germs on it transfer onto your hands. After this, you can suffer from infection if you touch your eyes, nose, or mouth.

Insect Bites

Insects and parasites, too, can act as hosts and carriers of infection. Diseases can spread quickly from one person to another whenever the insect bites a person. Illnesses like these and more are preventable, but the risks may increase multifold without the right precautions and treatments. Suppose you are looking for more information on prevention, treatment, and diagnosis. In that case, we suggest you book your next visit to an urgent care center and rule out the possibilities of testing positive for any of the dangerous infectious diseases.
