Influenza, or more generally recognized as the flu, is a virus that affects the upper respiratory system and can infect both humans and animals, but generally circulated throughout humans. It is an eminently contagious illness that is continually changing and has three known strains, Influenza A, B and C. While C causes nothing other than a few minor symptoms, its counterparts B and A can be disrupting, uncomfortable and in serious cases, lethal. Influenza A and B can both cause epidemics and pandemics
During the 2 – dose vaccination, incidence declined between 67 percent and 76 percent (Varicella Active Surveillance Project, 2016). Varicella outbreaks declined 78 percent from 147 in 2005 to 33 outbreaks in 2012 in 6 states (Centers for Disease Control and Prevention, 2016). The reported outbreaks occurred in day care centers and elementary schools in the United States (Creed, Satyaprakash, & Ravanfar, 2009) Since report rates are low there is a scarcity of varicella data to inform a varicella
As globalization increases the flow of food, people and goods between areas, there are inevitable impacts on public health; many of these are negative. As noted in the reading, these include the promulgation of diseases, such as tuberculosis, mad cow disease, AID, cholera, malaria, and more (University of New York, 2016). Due to movement of humans, animals, and products, the average distance and speed of disease travel has increased over a thousand fold in the past two centuries, while incubation
disease caused by several type swine flu viruses known as Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) which is a strain belongs to the influenza family and endemic to pigs. There are several subtypes of Influenza A virus known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3. CDC has determined that this virus is contagious and is spreading from human to human. However, at this time, it not known how easily the virus spreads between
meningitis is caused by seasonal viruses, usually transmitted by cough, saliva or waste matter. Some of the viruses that cause meningitis are; chicken pox, HIV, mumps, herpes simplex, west Nile, rabies. Doctors may not be able to identify the specific virus which is responsible for the outbreak of this disease. Some other conditions such as Fungal Infection, Syphilis, Lyme disease,
Painful sores in the mouth can cause concern, but in most cases they are benign. Canker sores are a common oral complaint, but they are not cancerous or contagious, and they are not caused by the herpes virus. Canker sores are ulcers in the lining of the mouth, often due to irritation from certain foods, injury to the mouth or even emotional stress. Signs and Symptoms Canker sores are small, but painful, shallow ulcer that may appear in on the lips, cheeks, gums, tongue, palate or throat. They are
Viruses are tiny organisms that contain nucleic acid encased by a protein coat. Some are enclosed by an envelope of fat and protein molecules. This organisms cannot grow, reproduce or carry out their functions without a host cell. A virus invades living cells and uses their chemical properties in order to keep itself alive and reproduce. As they don’t have ribosomes they are not able to synthesise proteins and they are also unable to generate or store energy in the form of ATP. Therefore, they use
deadly, take the Influenza virus for instance. The Influenza strain is a constantly changing virus; they change from year to year, and as the flu virus reproduces their genetic makeup may change. Due to the genetic makeup changes in Influenza it can become resistant to the antiviral drugs that are used to prevent or treat the virus. What is the process? The virus can become resistant in many ways, it can happen extemporaneously or during the treatment process of the virus; also resistant may vary
Children can take two of the approved antiviral drugs—oseltamivir and zanamivir. Oseltamivir is recommended by the CDC and American Academy of Pediatrics (AAP) for the treatment of influenza in persons aged 2 weeks and older, and for the prevention of influenza in persons aged 3 months and older. Zanamivir is recommended for the treatment of influenza in persons aged 7 years and older, and for the prevention of influenza in persons aged 5 years and older. Zanamivir is used to treat symptoms
called roseola infantum, sixth disease, and exanthem subitum. What are the causes? Roseola is usually caused by a virus called human herpesvirus 6. Occasionally, it is caused by human herpesvirus 7. These viruses are not the same as the virus that causes oral or genital herpes simplex infections. Children can get the virus from other infected children or from adults who carry the virus. What are the signs or symptoms? Roseola causes a high fever and then a pale, pink rash. The fever appears first
