The infected area usually breaks out in clusters of blisters. After a couple of days the blisters crack, becoming more painful. These blisters can take weeks to heal. Also, the first time an infected person has an outbreak, they may experience flulike symptoms, and it is common for an infected person to have several outbreaks a year.…
Fortunately, most people infected with WNV will have no symptoms. About 1 in 5 people who are infected will develop a fever with other symptoms. Less than 1% of infected people develop a serious, sometimes fatal, neurologic illness. Headache, body aches, joint pains, vomiting, diarrhea, or rash. Neurologic illness can include headache, high fever, neck stiffness, disorientation, coma, tremors, seizures, or paralysis.…
The condition is usually caused by a virus infection, most often a parainfluenza virus. Fever and a hoarse voice are common with the croup. The Mayo clinic suggests seeking immediate medical attention if your child: Makes noisy, high-pitched breathing sounds (stridor) both when inhaling and exhaling Begins drooling or has difficulty swallowing Seems anxious and agitated or fatigued and listless Breathes at a faster rate than usual Struggles to breathe Develops blue or grayish skin around the nose, mouth or fingernails (cyanosis) Children between 6 months and 3 years of age are most at risk for croup, with peak incidence happening around around 24 months of age.…
• For this write-up, I will be focusing on strep throat in adolescents and adults, and will expand on the background of this sickness, prevention, and treatment. Strep throat is a bacterial infection caused by streptococcal bacteria, and it generally occurs in the pharynx. Since it is a bacterial infection, it can spread from person to person extremely easy. This may be why adolescents are very susceptible to this illness, because they tend to share drinks, food, and other objects with different people. These objects can then easily act as a vehicle of transmission for this bacteria, passing it from one person to another.…
Viruses are all around us in this world. They all vary in size, shape, genomic contents, and a variety of other characteristics. Some viruses are more deadly than other viruses and some viruses are very uncommon. There are some odd viruses that can cause a disease; be fought off by the immune system, but instead of dying retreat back into the host and lie dormant until another time. A common example of this type of virus is the Varicella Zoster virus.…
Scarlet Fever is an infectious bacterial disease affecting mostly children, and causing fever and a rash. It is caused by streptococci. Scarlet fever is one of those diseases that put fear into everyone's eyes when they heard someone around them had contracted it. The scarlet fever was first discovered in the 1600s by an english physician and researcher named Thomas Sydenham. Thomas had many other contributions like the treatment of smallpox.…
We have all had a virus at one point. Sometimes I go to the doctor with my mother and he will say something like, "all the tests came back negative so he probably has a virus. " That seems a little confusing because you would think they could tell what the virus was, but there are so many viruses that sometimes we as humans just catch a virus and have to deal with it. Obviously some viruses are not as powerful, but some are very serious and could even lead to death. Two common viruses are Influenza and Rhinovirus, I will write about those later in this paper.…
Evolution does not occur by itself. It uses thousands of organisms that twist together to form all the life on this planet we call home. In our world, nothing exists in isolation yet everything is weaved together to form a complex system of evolutionary changes. In isolation, parasites could not survive and reproduce, plants could not spread their seeds, viruses could not infect their host, and organisms could not form adaptations from their environment that allow them to slowly evolve into better-adapted organisms. Parasites are organisms that need a host to survive and reproduce.…
A) The infection process of a vertebrate virus consists of 6 stages. Provide the name for each stage and provide details of the events that take place at each stage using Influenza virus A as the model. The 6 stages consist of: Attachment, Penetration, Uncoating, Biosynthesis, Assembly, and Release. Attachment is when the virus attaches or “locks” itself onto an acceptable cell. This occurs because a protein receptor is recognized by the virus and the virus attaches to the cell.…
It often comes in the middle of the night. Your child may go to sleep feeling okay but can wake up gasping for breaths. What is Croup? Croup is a viral infection of the voice box and windpipe associated with signs of a respiratory infection, such as a runny nose, cough and low grade fever. Most cases of croup are caused by viruses, usually parainfluenza virus transmitted by airborne droplets from an infected child 's cough.…
EBV belongs to human gamma-herpesviruses which are able to establish latency in lymphocyte. About more than 95% of adults are carriers of the virus. A common disease caused by EBV is mononucleosis. Besides, EBV can transform and cause cancer. Every year, there are 200,000 new cases of cancer and more than 140,000 deaths worldwide.…
During the Fall season, we can expect the leaves to fall from the trees, the children to return to school and the weather climate to decrease slightly. Another expectant occurrence during this time of year is the increase in diagnosis of respiratory infections such as rhinovirus, bronchitis, and pneumonia. There is one type among them that may be considered the worst kind of respiratory infection, and that is the Flu, properly known as Influenza. Some crucial factors that intrigue medical professionals and researchers concerning this viral infection are the same factors that scare the general public such as: how one may contract the virus from a host who is unaware that they are carrying the disease, or how the CDC stated that…
Signs and symptoms emerges two and seven days after a person obtains the infection.…
Most RTIs pass without the need for treatment and you won’t usually need to see your GP. Symptoms usually begin 1 to 3 days after exposure to the virus and can last 1 to 2 weeks. Because your baby has such small nasal air passages, congestion and mucus can cause trouble breathing. Most babies do not eat well when they are having trouble breathing. Use a small bulb and saline drops to help clear the air passage.…
The article, “Is contaminated groundwater an important cause of viral gastroenteritis in the United States?”, by Floyd Frost, Twila Kunde, and Gunther Craun, published in the Journal of Environmental Health, October 2002, describes how due to the contamination of groundwater, from sources such as runoff and sewage treatment plant effluents, many studies have been conducted regarding human health risks from potential viruses in groundwater. Waterborne outbreaks often occur, and are probably caused by viruses in drinking water. Because viruses are hard to detect in humans and water post-outbreak, most outbreaks are unrecognized and underestimated. Waterborne virus outbreaks in groundwater systems tend to be uncommon, so some researchers speculate…
