Viral diseases

Most cases of meningitis in the U.S. are caused by a viral infection, but bacterial and fungal infections can also lead to meningitis. Depending on the cause of the infection, meningitis can get better on its own in a couple of weeks – or it can be a life-threatening emergency requiring urgent antibiotic treatment. Acute bacterial meningitis usually occurs when bacteria enter the bloodstream and migrate to the brain and spinal cord. It can also occur when bacteria directly attacks the meninges,…

Signs and Symptoms German measles is a viral infection most distinguished by a red rash that appears all over the body. Commonly known in the United States as rubella, it is one form of the measles virus. Generally a mild febrile viral disease it is identified by its maculopapular rash. Rubella can be difficult to diagnose due to symptoms similar to that of dengue, scarlet fever, measles, parvovirus, and the herpes 6 virus amongst others. Children often times do not present symptoms,…

Chickenpox’s causative microbe name is known as Varicella-Zoster virus. In the medical field its terminology is known as Varicella. Chickenpox is well acknowledged as one of the numerous childhood diseases that produces skin lesions (Bauman, 2014). Varicella is highly contagious because the virus can spread in the air when an infected person coughs or sneezes. It can also be spread by touching or even breathing in the virus from the varicella lesions (Clinical Overview, 2013). Varicella is…

cured, but people who have contracted it can take medication to control the symptoms. The virus is contracted through blood products or from mother to infant during pregnancy or nursing. The virus was found by multiple scientists at the Centers for Disease Control, in 1989. The scientists found that Hepatitis C was the result of nearly every case of hepatitis that wasn't Hep-A or Hep-B. The Virus once contracted gets into the bloodstream and attacks the cells of the liver. It mutates the cells…

to even more powerful viruses and ‘hot’ viral strains, according to a new study. Perfect” vaccines have been protecting humans against polio, mumps, measles or smallpox, but it’s the “leaky” ones, which we may have to start worrying about. Imperfect vaccines might pose a threat for future development, researchers found. According to a study published in PLOS Biology, inoculating chickens with a live Marek’s disease virus (MDV) vaccine can lengthen the disease transmission period, allowing…

This section introduces the background of gene therapy in Parkinson’s Disease, especially on brain cells targeting therapy. It provides the rationale for further proposal of brain cell targeted PD therapy based on Ultrasound-meditated microbubble delivered AAV vector or RNAi. 1.Parkinson’s Disease, a common CNS disorder with no adequate treatment in pharmacological approaches Parkinson's disease (PD) is a progressive, central nervous system (CNS) disorder, belonging to a group of conditions…

Respiratory Syncytial Virus (RSV) is a viral infection that affects young children and infants, but may also affect adults. RSV belongs to the family of paramyxoviruses and is classified in the genus pneumoviruses. There are at least ten polypeptides of RSV that exist. RSV is an ssRNA, enveloped virus ranging in size from 120-300nm, its envelope contains two proteins and two glycoproteins, according to virology-online. It has two subtypes A and B with, it is believed that subtype A exhibits…

infections by the immune system. The disease occurs when the normal function of tissue is impaired. Health organizations have for a long time tried to understand all causal agents of diseases as fight strategies against these agents including understanding surviving strategies, their cycle, and multiplicity once they infect a human being. This has facilitated discovery of therapeutic drugs for various diseases (Klepac et al., 2013). Vaccination against different diseases has led to the…

Similar to Tuberculosis and HIV, tinselsparkleitis shares similar destructive effects on the human body. Tinselsparkleitis is a viral infection caused by the spread of bodily fluids and having close contact with the infected victims. When a patient is infected, it could take up to two years for the victims to show any form of the disease and its symptoms. The beginning signs of the infection are flu like symptoms including fever, sore throat, fatigue, and vomiting with additional a small red and…

beliefs, medical reasons, and parents’ concerns of side effects. But whereas parents who choose not to vaccinate do so to avoid risks, vaccinations do save lives, given that vaccine preventable diseases can and will return. Diseases are dangerous, even deadly. Vaccines have weaken the majority of infectious diseases that…
