HCV is a disease the effects the liver slowly over a period of time. The virus persists in the site of the liver over a long period of time, so that the patients may not know that he/she has HCV. Over this period of time, the patient will develop fibrosis and cirrhosis which is permanent scarring and scarring to the liver tissue. This damage is ‘silent’, and many times patients do not know that this damage has occurred. After cirrhosis occurs, the liver is unable to heal itself leading patients to have “Stage 4 Hepatitis C” (CDC: Hepatitis C).…
Pros: Screening for Hep C would allow the spread and transmission of hepatitis to be significantly decreased by increasing the amount of cases that are caught and treated and increased prevention as many cases could be prevented by individuals knowing their status. Screening for Hep C also leads to improved patient engagement in their care and in interactions with medical providers, through which patients can speak with the providers about other things that are of concern or could become an issue, apart from Hep C. The total disease burden of Hep C would be decreased as screening would reduce the amount of cases that progress into the later stages, decreased costs for treatment of Hep C in the later stages, other comorbidities can be caught, and some cases of Hep C can be prevented from increased screening and awareness.…
The Herpes Simplex Virus, more well known as herpes, is a viral disease that causes sores and blisters. It can be spread by the direct contact of an infected area to a non infected area or by the infected area touching an object and an unaffected area also touching that object (such as towels, fingers, ect). There are two types of the Herpes Simplex Virus; herpes type 1 (HSV1) and herpes type 2 (HSV2). Herpes type 1, or oral herpes, usually consists of blisters or sores around the mouth area. Herpes type 2, or genital herpes, can cause blisters or sores around the genitals and rectum.…

Introduction Norovirus infection causes inflammation in the stomach and intestines (gastroenteritis) and food poisoning. It is caused by exposure to a virus in a group of similar viruses called noroviruses. Norovirus spreads very easily from person to person (is very contagious). It often occurs in places where people are in close contact, such as schools, hospitals, and restaurants. You can get it from food, water, surfaces, or other people who have the virus (are contaminated).…
Lastly, the prevention of the liver cancer is essential and critical. The liver cancer can be prevented by avoiding alcohol and lowering the risk of becoming infected with hepatitis C. (7) Besides prevention, the patients and their families should be aware of the course of this disease to deal effectively with overall patients’…
epidemic happened in 1930 and after that, it didn’t take too long to figure out that the bacterium was Rickettsia psittaci. It was later found that the source was birds, including parrots, cockatoos, etc. Long after Lyme disease came about, a man named Allen Steere and others began to think that this disease comes from ticks, specifically a deer tick. Many people believe that the white-tailed deer is the host from which the deer tick gets it sustenance, but in reality, the deer don’t had the spirochete that causes the disease. It’s been found, though, that white-footed mouse do.…
Introduction Upper gastrointestinal bleeding can be manifested with hematemesis, melena or hematochezia. Acute bleeding due to gastroesophageal varices in cirrhotic patients is associated with higher morbidity, mortality rates as well as development of life-threatening complications. This bleeding significantly increase protein concentration in the bowel which results in increased ammonia production by colonic bacteria and precipitation of development of hepatic encephalopathy [1].…
As defined by the American Liver Foundation, cirrhosis “is the scarring of the liver with hard scar tissue replacing soft healthy tissue” (American Liver Foundation, 2015). Cirrhosis can be caused by multiple conditions including alcoholism, non-alcoholic fatty liver disease, Hepatitis C and genetic diseases such as Wilson’s Disease (ALF, 2015). In a study released by the Chronic Liver Disease Foundation (CLDF), “ patients with cirrhosis from alcoholism have more brain deterioration with HE compared to non-alcoholic cirrhosis patients” (Ahluwalia et al., 2015). Almost half of patients with cirrhosis will be diagnosed with HE during their clinical course, some repeatedly (Vistrup et…
Thierry Work leads a team of wildlife disease researchers at the U.S. Geological Survey who study sea turtles. Recently, they turned their attention to the ChHV5 virus. The virus infects endangered green sea turtles, who then develop tumors. Eventually the infection weakens the turtle’s immune systems and the turtles die.…
HSC BIOLOGY: THE SEARCH FOR BETTER HEALTH RESEARCH ASSESSMENT - HEPATITIS B OVERVIEW OF HEPATITIS DISEASES Hepatitis is an inflammation of the liver (In Latin, hepatitis means “of the liver”) caused either by a toxic substance (viral infection from direct damage e.g. alcohol) or bacterial and viral infection. Hepatitis is a family of viral infections that damage the liver; most common types are Hepatitis A, B and C. About 500 million people globally are infected by one of six hepatitis viruses. Five different viruses - named A, B, C, D, and E are known to cause hepatitis. All forms of viral hepatitis have common symptoms, with each varying in severity, duration and treatment.…

“Herpes simplex viruses types 1 and 2 (HSV-1 and HSV-2) are human neurotropic viruses that establish latent infection in dorsal root ganglia (DRG) for the entire life of the host (Steiner, I., & Benninger, F., 2013, p. 1).” Herpes is known as a sexually transmitted infection that has no known cure. This type of STI is transmitted through sexual contact and bodily fluids. People need to be aware of the types of transmission, clinical manifestations and diagnostic studies that confirm herpes is present in their body.…
