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,…

Chickenpox is a contagious infection that is caused by the varicella-zoster virus. Everybody can be infected by the varicella-zoster virus but it effects younger children’s more. Chickenpox can last up to 15 days Symptoms: A itchy rash that causes blisters with fluid, and once the blister erupts it causes to develop a crust. Also fever, feeling tired, headache, and anorexia is common. Treatment: The body has to fight the virus on its own. For the symptoms special creams to prevent from itching,…

the E.coli strains live in the human intestine, they also provide vitamin K and B-complex. Whereas, a T-4 bacteriophage or T-even bacteriophage, is harmless…

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…

words of Bill Gates, a co-founder of Microsoft. Gene therapy is one of the most dynamic therapies in the medical field and most people underestimate it. Gene therapy can cure common diseases like these and it is a method that has recently brought the world to seek medical treatment in a new way. In-depth gene therapy research has been happening since the late 20th century and a recent breakthrough is allowing it to accomplish unheard of tasks. Genetic therapy has become a revolutionary medical…

have begun to explore such an option. One of the first viruses to be used in such manner is an engineered herpes virus, capable of provoking an immune response against cancer. Since this discovery the Food and Drug Administration (FDA) has approved a genetically engineered virus known as talimonogene laherparepvec, or T-VEC for short. This cancer fighting virus, known as an oncolytic virus, is approved to treat patients suffering from melanoma, a skin based cancer. Since the 1800s physicians…

reactivate and the virus starts transcribing its genes again. It is important to state that once a person has been infected with Herpes Simplex Virus, this virus will remain latent in the hosts body for years and will eventually reactivate periodically causing the disease. Different stimuli can cause the virus to leave its dormant state such as, fever, trauma, emotional stress, sunlight, and menstruation. Herpes Simplex Virus can be transmitted into the host body through direct contact between…
