Post an explanation of the disease highlighted in the scenario you were provided. Include the following in your explanation:

1.The role genetics plays in the disease.
2.Why the patient is presenting with the specific symptoms described.
3.The physiologic response to the stimulus presented in the scenario and why you think this response occurred.
4.The cells that are involved in this process.
5. How another characteristic (e.g., gender, genetics) would change your response.

Streptococcal pharyngitis

1. The role genetics plays in the disease

The patient suffers from Streptococcal pharyngitis, which is also called strep throat.  It is an infection that happens at the back of the throat, where the patient portrayed similar symptoms. This is an infectious disease meaning that the patient could have contracted the disease from another infected person. This is one of the most common infections across the world. However, very little is known about which genes are expresses and which genes regulate expression during acute infection. Micro rays are increasingly getting incorporated in research due to their ability to provide genome-wide views of the gene expression at one time.

2. Why the patient is presenting with the specific symptoms described.

The patients have such symptoms since he has a sore throat, fever and tonsils. He also had a headache, tonsils, and having enlarged lymph nodes in the neck.  One may get the exposure to the virus after one to three days after exposure and last seven to ten days (Kalra, Higgins, & Perez, 2016).  However, some of the symptoms may include touching the eyes, nose, and mouth, which may also involve having a skin infected with group A strep.

3. The physiologic response to the stimulus presented in the scenario and why you think this response occurred.

This infection can cause a behavioral change for the patient due to the reaction that he/ she faces after acquiring the infection.  A person may be affected due to exposure to the disease. This is a factor that, in most cases, enhances the rate of the infection.  The virus is also improved upon contact with infected persons, where there may be crowding in areas such as market places schools and other institutions (Wessels, 2011).  Food could also, be a major factor in the case of cases of contaminated foods.

4. The cells that are involved in this process.

It is relatively easy to transfer the virus from one person to another. This test hence plays a vital role in ensuring that the virus will significantly naturally affect the body. Therefore, to test the infection, the doctors are recommended to use the throat culture to identify its cause and harm the body. There can also be the use of the rapid test, which is quicker but with lower sensitivity (Lim, Boyanton, George, & Sims, 2019). These ways help in identifying the cause of the symptoms and also establishes a definite diagnosis. For children to conform to the virus’s positivity, there has to be a throat culture, which helps confirm the results.

5. How another characteristic would change your response.

It is apparent that the infection of this virus are mostly adults.  Some of the factors that affect a person include his/her genetics, which somehow affects the person’s ability to control the rate of infection. Other factors that could affect a person include his/her immune system, where it is relatively easy to acquire the disease with a low immune system. A person with other pre-existing conditions such as HIV, which may affect his reaction to the illness and limit the ability to limit from having the many symptoms expresses. Group A β-hemolytic Streptococcus is a significant cause of the virus (Lim, Boyanton, George, & Sims, 2019). However, it can be caused by other bacteria such as non–group A β-hemolytic streptococci and fusobacterial. As a result. Having a close relationship with people ole may be the biggest threat of acquiring the infection.  Other factors may include sharing a toothbrush or similar items such as contaminated foods.
