Herpes simplex virus

Herpes is a common sexual transmitted diesease. Genital herpes is caused by two types of viruses. In the United States one out of every six people get genital herpes. You get genital herpes by having vaginal, anal, or oral sex with someone who has the disease. Fluids found in a herpes sore carry the virus and contact with those fluids can cause infection. You can also get herpes from an infected partner who does not have a visible sore or who may not know he or she is infected because the virus…

Recent study reveals cat-scratch disease is rising among adults Say goodbye to regular cuddle sessions with your beloved kitty, because their claws could harm you. According to a recent study by the Center for Disease Control and Prevention (CDC), there has been an increase in cat-scratch disease (CSD) patients. The study revealed that 13,273 people were diagnosed with CSD during 2005-2013, and 538 of the diagnosed patients were later hospitalized. CSD is a bartonella bacterial infection…

By Jonas Wilson, Ing. Med. Lichen striatus Lichen striatus (LS), also known as Blaschko linear acquired inflammatory skin eruption or linear lichenoid dermatosis, is a benign, rare and self-limiting inflammatory skin condition. It primarily affects children between the ages of 5 to 15 years. LS initially presents as pinkish-red or flesh colored spots that coalesce over a two-week period (or less) to form a dull and scaly linear band. Lesions associated with LS tend to occur more frequently…

may be altered to treat a disease, it won't change the chance that the disease will be passed on to the patient's children. This is the more common form of gene therapy being done.” (Gene Therapy and Kids.) This type involves attaching the gene to a virus called a vector. The other type is germline. Kids Health says, “(Germline gene therapy)Involves modifying the genes in egg or sperm cells, which will then pass any genetic changes to future generations. Experimenting with this type of therapy,…

and about 15,000 of them died. Hepatitis A Hepatitis A virus causes liver disease, which can result in fever, loss of appetite, fatigue, stomach pain, vomiting, and yellow skin or eyes (jaundice). Children younger than about…

It has many functions such as delivering the genome, interactions of virus with cells, and includes protection of the genome from nucleolytic enzymes. The virion extended tail fibres and hits the bacterium and the bacteriophage is triggered and starts hosting the virus. The structure of a T-even bacteriophage consists of a head in an icosahedral shape, 20 sides, which is called the capsid. Attached to the capsid is…

influenza virus was infecting its hosts long before the discovery of viruses in the late 1800’s. The longevity of the virus can be attributed to its ability to quickly mutate its genome, which consists of only eight negative-sense RNA segments. These small mutations allow the virus to rapidly evolve. In fact, approximately every twenty to thirty years the virus evolves into a “super virus” capable of causing significant pandemics (Webster, 2014). The influenza A virus is the envelope virus…

transmission is primarily via droplets from respiratory secretions and can spread via blood exposure. This is a common illness in the spring months. Etiology Erythema infectiousum is caused by Parvovirus B19. This is a non-enveloped single-stranded DNA virus belonging to the Parvoviridae family. Pathophysiology Viremia from Parvovirus B19 exposure usually occurs within 5-10 days, and the patient remains contagious approximately 5 days after viremia occurs. If an immunocompetent host is…

body, creating health hazards as minor as the common flu and as disastrous as the AIDS epidemic. Viruses have many types; one is an RNA virus. RNA virus is a virus that has RNA as its genetic material. One of the human diseases that is caused by RNA virus is the Ebola virus. In order for someone to be infected by Ebola, one must come into contact with the virus. It can enter the human body through the nose, mouth or breaks in the skin. Once inside, it finds a host cell to infect. The viral…

surrounding it. This includes historical outbreaks of the virus, the causes of worldwide pandemics, and ways the virus may be prevented. There are three main types of this virus. “All three types can infect humans; however only type A can cause a pandemic. Type B causes severe illness and death in humans but only mild epidemics. Type C causes only mild illness in people” (Barbour 11). The common cold would be an example of a type C virus. There…
