and joints. The need for the flu shot is at an all time high in todays society. Each year the flu is different and can affect people in different ways, thus scientist need to make a different vaccine every year to combat different strains of flu viruses. Healthy people can contract the sickness and spread it to others, this is why the flu shot is necessary for everyone. Since 1976 to 2007, “estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of…

flu” Pandemic was caused by an avian-like influenza virus that gained the ability for efficient and sustained human-to-human transmission and then spread globally, killing 20-50 millions. Fortunately, viruses with pandemic potential are rare occurrences and ongoing surveillance of human and avian viruses is being done globally in preparedness for an influenza pandemic. Vaccines and anti-viral drugs may be available, if needed and time permits. Both kinds of therapies have shown some…

Viruses are infective agents that are unable to support themselves and rely on other hosts for survival. Although they are not a living thing, viruses are able to infect humans, plants, bacterias etc. Depending on the type of virus, they target a specific organ or type of cells and inject their DNA or RNA in the cell to reorganize the genetic material of the cell. The cell then follows the new DNA instruction and produces more viral viruses. The adenoviridae, better known as adenoviruses, are a…

A flu is a contagious respiratory infection caused by a variety of flu viruses. Symptoms of flu may involve headaches, fever, and sometimes soreness. While some other symptoms may include cough, sore throat, and gastrointestinal problems. There are 3 main types of flu. Influenza A viruses are the most harmful, as they can cause severe disease.influenza is usually responsible for the majority of seasonal flu cases. It is found in humans and in animals. Influenza A is spread from person to person…

their lipid droplets to to accumulate, assemble and bud off into the rest of the body. Liver produces and secretes LDL, VLDL and HDL which are taken up by every cell in the body that uses cholesterol, including the liver cells that take them up too.2 Viruses hijack these lipoproteins and use them to get into the liver cells, where they replicate, which opens up a gateway to the rest of the body. They replicate within the endoplasmic reticulum and then use the lipid droplets as scaffolds. After…

Overall, this video explains the positive outcomes of using viruses, that once were considered deadly, to treat cancer. The documentary shows how ongoing research and trials of this kind of treatment is happening simultaneously in different places, and using different viruses. The first case mentions the study developed by Dr. Bell, who concluded that smallpox viruses can attack, and kill cancer cells without harming surrounding cells. Therefore, he and his team are working in treatment trials…

and combining it with rabies we could end up having entire new genetically altered supper virus. That altering the genetic code of rabies could result in a hybrid and possibly a zombie virus. In Ker article he talks about the genetic makeup of a viruses and how it’s possible for the virus to swap certain attributes with another pathogen. Ker calls this Re-assortment, if the virus has enough likeness with another it can swap genetic coded back forth each other. Because of this fact rabies is not…

or unfavorable environmental factors; illness; sickness; ailment (“The Definition of Disease”). Disease has been around for as long as humans can go back, and because of the many viruses and bacteria present in almost all things (animals, plants, and people) it is quite impossible to completely avoid. Although viruses and bacteria can not completely be avoided, they can, however, be somewhat slowed down or prevented in most human beings -- this is where vaccinations come into action.…

an organism inside its host. It, in essence, is a parasite. Viruses have the ability to infect animals, plants, bacteria and archaea. Although there are millions of strains of viruses, in modern science, about 5000 viruses have been identified. Hence, the study of viruses is known as virology, which is a subset of microbiology. Examples of a virus known as the bacteriophage, which harm bacteria, when used properly, help humans. Viruses when gone through transduction, specific genes can be…

In an instant the flu viruses charged at the immune system warriors and the warriors charged at the flu viruses and the battle for the body began. At first Mac the macrophages began to engulf tens of hundreds of the flu viruses taking in mouthfuls. The way that the virus was able to counter the attack was by infecting some of the macrophages that were destroying them. This allowed the viruses to replenish their number, but the NK knew what had to be done and…
