What is Symptom | Swine flu, what are the symptoms

Symptoms - this post will examine more deeply what is meant by Symptom and all information about the Symptom in relation to the swine flu, and here I give the sense Symptom Symptom according to wikipedia and viruses associated with pig flus, other than that I also gave FAQ's about Symptom I get from www.telegraph.co.uk
Symptom, is a departure from normal function or feeling which is noticed by a patient, indicating the presence of disease or abnormality. A symptom is subjective, observed by the patient, and not measured,
Symptoms may be chronic, relapsing or remitting. They also may progressively worsen or progressively become better (convalescence). Conditions may also be classified as symptomatic (present and demonstrating symptoms) or asymptomatic (present but without symptoms). Asymptomatic conditions and asymptomatic infections can exist for many years undiagnosed and may only be found upon medical testing (such as high blood pressure).
Constitutional or general symptoms are those that are related to the systemic effects of a disease (e.g., fever, malaise, anorexia, weight loss). They affect the entire body rather than a specific organ or location.
The terms "chief complaint", "presenting symptom", or "presenting complaint" are used to describe the initial concern which brings a patient to a doctor. The symptom that ultimately leads to a diagnosis is called a "cardinal symptom

Non-specific symptoms are those self-reported symptoms that do not indicate a specific disease process or involve an isolated body system. For example, fatigue is a feature of an enormous number of medical conditions, and is a documented feature of both acute and chronic medical conditions, both physical and mental disorders, and as both a primary and secondary symptom. Fatigue is also a normal, healthy condition when experienced after exertion or at the end of a day.
Swine flu: what are the symptoms
Q: What are the symptoms?
A: The symptoms of swine influenza in people are similar to the symptoms of regular human seasonal influenza infection and include fever, fatigue, lack of appetite, coughing and sore throat.

some people with swine flu have also reported vomiting and diarrhoea.

Q: What is swine flu?
A: It is a contagious respiratory disease of pigs caused by type A influenza viruses.
Pigs are hit by regular outbreaks.
There are many different types of swine flu and the current cases involve the H1N1 strain of type A influenza virus.
Q: How do humans catch it?
A: While people do not normally catch it, humans can contract the virus, usually if they have been in close contact with pigs.
It is also possible for the constantly changing infection to spread from person to person, which has happened in the latest outbreak.
Experts believe it spreads in the same way as seasonal flu – through coughing and sneezing. You cannot catch it through eating pork.
Q: What is the difference between swine flu, avian flu and the flu commonly seen in the UK during the winter?
A: Influenza viruses are commonly circulating in the human and animal environment, with different strains causing illness in humans, bird and pigs.
Seasonal influenza is caused by viruses that are adapted to spread in humans.
Humans have some natural immunity to the strains that are in common circulation, and this immunity can be boosted by immunisation with a vaccine.
Avian influenza is caused by influenza viruses adapted for infection in birds.
Similarly, swine influenza is caused by influenza viruses adapted for infection in pigs.
These illnesses all cause the same respiratory symptoms in sufferers and can be passed between one another.
Q: How dangerous is it?
A: More than 150 people have died and thousands made ill,.
However, testing has shown that the antiviral drugs oseltamavir (Tamiflu) and zanamivir (Relenza) appear to be effective against the human swine influenza H1N1 strain,
Q: Why should we be worried about it?
A: The World Health Organisation warned the outbreak had "pandemic potential" and countries were advised to step up surveillance and preparation in case the infection spreads rapidly.
Flu viruses have the ability to change and mutate, making it difficult for drugs manufacturers to ensure effective vaccines are available.
The new version of the H1N1 virus is a mix of different animal and human versions of the disease. Mixing can lead to the development of changed viruses to which humans have little immunity.
Q: What is a pandemic?
A: If the flu spreads over a wide geographic area and affects a large proportion of the population it goes beyond an epidemic and becomes a pandemic.
According to the Health Protection Agency, an influenza pandemic is defined as a new or novel influenza virus that spreads easily between humans.
When new influenza viruses are introduced into the environment, humans do not have any natural immunity to protect against them.
Therefore, there is a risk that new influenza viruses could develop into a pandemic if the virus passes easily from human-to-human.
Q: Is it in the UK?
A: Swine flu has already spread to the UK.
Anyone who has recently returned from affected countries should consult a doctor if they notice flu-like symptoms.
Q: What is being done in the UK to prevent the infection?
A: The HPA said it is working with the UK government to review the current incident and any threat it poses to UK public health.
It advised people to follow general infection control practices and good hygiene to reduce transmission of all viruses.
This includes covering their nose and mouth when coughing or sneezing, disposing of dirty tissues promptly and carefully, washing hands frequently with soap and water and cleaning surfaces which are regularly touched
