Which of the following Diseases would not Normally be Spread by a Common Source?

While vaccinations are an important part of modern medicine, a disease can spread otherwise. Understanding how diseases spread is an important aspect of preventing sickness in your community. Some diseases cannot be transferred via a common source, but most can; the focus of this article is to briefly outline. When certain diseases are and are not spread using a common source.

When it comes to the spread of viruses, bacteria, and other disease-causing microorganisms, a “common source” is a basic premise. If there is a single item that everyone who became sick was exposed to. If everyone was exposed to the same strain of bacteria. Then those are both examples of a “common source.”

Which of the subsequent Diseases wouldn’t commonly be unfolded by a standard Source?

The answer is Typhus. Typhus is spread by fleas, but it doesn’t normally come from a common source. It’s more likely to spread through contact with an infected person or animal. Than from a common source like a food item or water supply.

The other choices are all diseases that could spread by a common source. Hepatitis A will transmitted through contaminated food or water. Salmonella can carried in contaminated food or water. As well as by contact with animals and people who are infected. Listeria monocytogenes can found in uncooked meat, unpasteurized milk and dairy products (like cheese), and undercooked foods made with raw eggs (like ice cream).

The common source of most diseases is a contagious person. So the answer to this question is “none.” However, some diseases are not spread by a person. For example, HIV is transmitted through bodily fluids and can only transfer from one person to another through sexual contact or sharing needles.
