The influenza virus essay

influenza history

Epidemic influenza occurs annually and is attributable to minor changes in genes that encode proteins on the surface of circulating influenza viruses. These epidemics have major medical impacts, but they are generally not fatal except in certain groups such as the elderly.

Where does the flu come from

At this point in time it is generally recognized by the international medical community that Avian Flu is bound to become a pandemic, most likely within the next ten years. Within this camp there were thousands of mules and horses. Not only that, but it easily crosses species. Flu outbreaks usually peak at around January, but they can happen as early as October. As we keep track of the new cases and of the fatal ones, they have urged the public to stay calm as they are trying to do everything in their power to put an end to this Prevention Flu vaccination is the best protection against flu. Virus shift can also occur when an avian strain becomes adapted to humans, so that the avian virus is easily transmitted from person to person.

People are currently rushing to get flu shots to try to prevent this virus, which can be temporarily debilitating and even lead to death 1. Adult healthy volunteers will receive the experimental vaccine or a placebo and will be monitored over time to evaluate their immune responses.

influenza causes

So for example, segment 4 contains the instructions to make the HA protein, and segment 6 contains the instructions to make the NA protein the segments are numbered in size order, with 1 being the largest.

Even though the influenza virus can sometimes be compared with the common cold.

Type c flu

There are medications to treat the flu, but these are expensive and not as effective as vaccination plus need to be started within hours of the onset of signs and symptoms. Here are several tips that can help you and your child against the risk of contracting this disease: Teach them proper hygiene - Flu viruses usually spread by direct contact, thus teaching children the proper hygiene will immensely help in lowering their against this disease Clearly, a more rapid method of vaccine development is needed. The NA protein is needed for the virus to exit the host cell, so that the new viruses that were made inside the host cell can go on to infect more cells. Often called flu, sometimes-even grippe. Although it is called swine flu, the new H1N1 virus is transmitted from person to person, and not through contact with pigs or pork products. Influenza virus is one of the most changeable viruses known. Developing improved methods for measuring immune function in humans. RSV, parainfluenza, and coronaviruses do not yield lasting immunity, although the course of reinfection is often less severe. Several strains of the influenza virus compose collectively of the flu, and these strains mutate — or alter their genetic composition — as the virus creeps into and out of the people and animals it infects.

This project has enabled me to better understand the general process for antiviral and antiretroviral drugs to include safety and efficiency assessments, fielding, antiviral drug resistance and overcoming resistance using multiple drug combinations Not only that, but it easily crosses species.

Upon returning home from the fronts, the soldiers were not only welcomed home by the citizens of America, but also introduced a new threat that led to much desolation throughout the American nation.
