Disease Transmission

Disease Transmission

Noninfectious and infectious diseases are completely different. Infectious diseases like tuberculosis, HIV/AIDs, malaria, and polio are easily spread directly or indirectly from one individual to the other. Also, they are caused by pathogenic microorganisms like Viruses, fungi, parasites, and bacteria. Common modes of transmission of Infectious diseases are respiratory, fecal to oral transmission, direct contact, sexual transmission, and vector transmission (Hofrichter, 2012).On the other hand, the non-infectious disease is the kind of diseases that are not shared from one person to the other and are also not caused by a pathogen. Historically, infectious disease used to cause more deaths, but today non-infectious disease such as cancer is the most threatening. Since both infectious and non-infectious diseases are spread through various ways, it’s essential for the public professionals to develop, know and come up with the means to prevent their spread. It’s important for the public health to educate the public on how to avoid the spread of these diseases such as the need to wash hand, not holding contaminated things and to covering themselves when they are coughing (Battle, 2013). Apart from this simple practices and providing vaccines, public health needs to investigate and diagnose health threats with their communities.

There are several programs and tools that professionals in public health can use to have a meaningful dialogue with the public. Among of the tools is the use of the technologies such as social media like blogs, network platforms, and virtual reality. Majority of the public especially the youth spend most of their time online, and hence public health can take advantage of this to educate several members of the public (Ventola,2014).  However, the professional should make sure the information they provide is correct. Also, they can form organizations to promote national policies, programs and develop resources that will see to it that local health is improved and in the process engage in as meaningful dialogue that will see that everyone is aware of how to avoid both infectious and non-infectious disease.
