Taking Charge of Your Asthma

Very much confused with the common cold, influenza or flu is a graver disease and brought about by a distinct type of virus. In a similar manner, the gastroenteritis that is not related is at times referred to as stomach flu or 24 hour flu.

The influenza virus would be an RNA virus of the Orthomyxoviridae which makes up the influenzaviruses, Thogotovirus and Isavirus. There would be three varieties of flu virus: Influenzavirus A, Influenzavirus B and Influenzavirus C. Influenza A and C can inflict infection on a lot of species, when influenza B has an exclusive effect on humans.
Type A viruses would be the most virulent of the human pathogens among the three flu types and makes the most severe of diseases. The grave Influenza A virus may be divided in various serotypes with a basis on the antibody response to the viruses.

Influenza B virus would just be exclusively a human pathogen, and appears less common than influenza An other animal which is regarded to be susceptible to influenza B infeation would be the seal. Such an influenza would mutate at a rate that is 2*3 lower compare to type A, and as a consequence would be genetically diverse, with only one influenza B serotype. Because of such antigenic diversity, immunity to influenza B is at an early age.

The influenza C virus causes infection on pigs and humans, as well as inflict severe illness and local epidemics. But influenza C is not as common compared to the other types and would seem to cause disease in children.

The virus is renowned to spread from one person to another through small particle aerosols that are less than 10 ¼ diameter that enters into the respiratory tract. It could also live for a short time on surfaces and could be spread through the said route should the virus be introduced in the nasal mucos before losing infectivity. The incubation period would be considered short, aroung 18 to 72 hours. The virus concentration in the nasal and tracheal secretions will stay high for 24 to 48 hours after the symptoms begin and could last a while longer for children. Titers would be quite high, and there would be a couple of infectious virions within a small droplet to begin a new infection.

The flu virus would have an effect on the epithelial cells of the respiratory tract. The cells will die in part because of the direct effects of the virus on the cell, and probably because of interferon effects. Cell death that are coming could also come from the actions of the cytotoxic T-cells. Because of this, the effect of the ciliary clearance will be reduced, leading to the impaired function of the mucus elevator, therefore ther will be reduced clearance of infectious agents in the respiratory tract. The gaps in the protective epithelium will give other pathogens access to the other cells, but viremia is quite rare.
Interferon could have a role in the reduction of virus production. A lot of the symptoms of uncomplicated influenza which are muscle aches, fever and fatigue would be associated with an efficient induction of interferon. The cell-mediated immune reponse is significant in viral clearance. The antibody response would not usually be an issue until the virus has been cleared. The repair of the respiratory epithelium will start rapidly, but could take time to complete.

Knowledge on Bird Flu or H5N1 Virus
How this virus is often referred to is H5N1 or HPAI A (highly pathogenic avian influenza virus). The existing form of the bird flu virus would be a fast mutating virus and very pathogenic in form than the previous strains until the date. The viruses are evident in the respiratory system of a lot of species of birds.

The viruses of bird flu are composed mostly of subtypes of the Influenza Virus A. There are a lot of H5 and H7 subtypes of the virus that is the root of the bird flu among the birds. The wild birds are known to be the reservoir of bird flu virus for ages. The migratory birds bring along with them pathogens from different places, and in turn will infect the population of the birds responsible for deaths.

Up until 1997, the virus had a renown to be relegated to arboreal species and pigs. They have never had an effect on humans back then. However, deaths in Hong Kong plus other parts of the Southeast Asian countries have caused alarm in the medical world. Though it was of knowledge that the bird viruses had adapted themselves to be strong to have an attack on mammals just as on humans and on dogs. The bird flu virus has been referred to as the H5N1 virus, which is a subtype of the H5 viruses.

H5N1 has developed into a form that could infest humans and other mammals, and the impact of this will be fatal enough to commit destruction on the hosts. They would generally attack the respiratory system, and symptoms have a large similarity to normal flu. It is refered to as a panzootic virus, which implies it could create an attack on other species.

Studies that are mad on them refkect that they continuously evolve via antigenic drift. They would cause infection on humans via direct contact with birds that are infected, or the patients who have the bird flu. The infected birds would pass the virus through the environment via nasal secretion, feces, blood droplets and saliva. The virus gets into motion through the human body via the nasal cavity or the mucous membrane of the eyes.

The H5N1 virus has indeed turned into a nightmare due to its tendency to mutate quickly, and the evolving status could take it to a dangerous form. Scientists who are using their resources on the bird flu have the view that the consequence of the combination of the H5N1 virus along with the human flu virus may be too complicated that before anything would be regarded that it would wipe over millions of lives.
Precaution is of significance. So should there be an outbreak in the area, prepare to defy bird flu virus with proper care and implement methods made by the health department in the area.

Vitamin C to Fight Colds and Flu
With the entry of winter, there also lies the possibility of becoming sick for a lot of people. A lot of Americans go under just one bout of the flu or the cold yearly, which would bring about millions of hours of lost work time, millions of dollars made on the remedy products, as well as flat-out despair. Such people who have the cold or flu will end up getting syrups, lozenges, tablets and pills that aren’t made to rid of the ailment, however just suppress the different symptoms in its place.

There has been no known cure as of the present for the various virus strains behind the flu and colds. But conventional medicine has made an attempt to suppress flu and cold symptoms, many of the products would be relatively ineffective, and go along with various side effects. It is a good thing that there are natural methods as well as products that aid to stop infection from flu and cold viruses, and also aid in shortening the duration and lessen the severe impact of an infection from flu or cold.

The distinctions between a flu and a cold would often not be detected immediately. But there are also notable differences. Though there are more than 20 identified major virus groups, a lot of the groups just hail from 5 of each. The three other virus groups make flu, which are usually noted as A, B and C strains. The flu types B and C would just be mild in adults, both of which could be mistaken for bad colds. As soon as a person experiences a type C flu, they would usually have immunity, but children could get it more than once. The type A virus would be the least stable and the most volatile, as it would change genetic makeup a lot. The type A strains would cause a lot more severe symptoms compared to a cold, and individuals would not generally have an immunity to it. The virus located in the type A flu would be the viruses behind epidemics.
The flu would always come as more severe than a cold, as it would usually be accompanied by chills, fever and aches. The coming of a flu would also be much more rapid compared to that of a cold, with the flu usually lasting at times from a few days up to a week. But the residual effects of the flu could last up to a few weeks.
Majority of the colds come from one of the 5 virus families, with around half arriving by way of the rhinovirus family. This rhinovirus was not officially detected up until the late 80s. The colds would just be kept to the nose, throat and the surrounding air passages and mostly do not bring fever, chills, or the severe symptoms that go with the flu. It is a bad thing that the duration of the symptoms of a cold would be longer than that of the flu, as it at times lasts several weeks at a time.

Viruses would be the cause of majority of symptoms located with the cold or flu. They would be involved in the cause of the symptoms in many ways. First, a couple of the symptoms of a cold would be caused by the body’s own response to the infection. A couple of these symptoms are fever, cough, runny nose, sneezing and watery eyes. Viruses would often prompt what would be regarded as a disease process, wherein antibodies are made that attach to the viruses they are fighting as both go through the body.

The virus has the ability to damage or destroy the vital organs which they invade. Dependent on the extent of the infection in the organs, along with the invasion of virus overall, the immune system of the body could be worn down, making it more prone to other infections. It is a good thing that nature gives relief., Those who encounter suffering from the cold or flu could take vitamin C, known to lessen the severity as well as the length of a cold.

Yearly the flu will affect people, and there would be little to do except for being clean through regular washing of the hands. Though the flu could not be prevented, vitamins including vitamin C could help lessen the length and severity the cold one would have. Good vitamin C is not so expensive and can be picked up from an online or a local health store.
