General Health asked:


A swine influenza virus has health officials around the world working to contain the outbreak of growth. One in five residents of Mexico for the most populated city wore masks to protect against virus, Mexico City seems to be the epicenter of the outbreak. As many as 103 deaths have been attributed to the swine flu so far with many more to be feared in the background. The health department said a Mexico 1614 cases have been documented.

So far, however, only 18 deaths in Mexico have been confirmed by laboratory tests after Swine Influenza Virus and was reported to the World Health Organization as such.

In the U.S. have been improved in preparation for a possible outbreak of swine influenza virus after 20 cases, the first cases of the virus in Canada was reported on Sunday – six mild cases.

Swine influenza or swine flu is a contagious respiratory illness that usually only found in pigs. It is caused by a type A influenza virus. Outbreaks occur in pigs throughout the year. The current strain is a new variation of the H1N1 virus, which is a mixture of animal and human versions.

Normally, the swine influenza virus is spread from person to animals it contains, but when the spread of the flu is spread from person to person, you can continue to mutate, making it more difficult to combat because people do not have natural immunity.

The symptoms are similar to common flu. Which include fever, lethargy, lack of appetite, cough, runny nose, sore throat, nausea, vomiting and diarrhea. Learn more about swine flu and how to treat the link below.

The swine flu virus spreads when an infected person coughs or sneezes on another person. People can become infected by touching something with flu viruses on it and then touching your mouth, nose or eyes.

Calling it a “public health emergency of international concern” of the World Health Organization (WHO) is very worried. WHO also said that a public health emergency is an occurrence or imminent threat of illness or health conditions caused by bioterrorism, epidemic or pandemic disease, or highly fatal infectious agents or toxins that pose serious risk to a significant number people.

Protection against swine influenza virus?

Expert advice on health is to follow the instructions for common sense: wash your hands, staying home if ill and listen to their local health authorities. The advice from the CDC about the situation is “very frequent hand washing is something we talked again and again and that is an effective way of reducing disease transmission.” It also advises, “If you’re sick, it is very important that people stay at home. If your child is sick, fever and flu-like illness should not go to school. And if you’re sick, you should not get on an airplane or other public transport to travel. Those things are part of the personal responsibility to try to reduce the impact. “

The symptoms of swine flu

It is also noted that Symptoms of Swine flu is relatively general and not specific. “So many things can cause these symptoms. It is a dilemma,” says one doctor interviewed by CNN. “It’s a challenge we’re wrestling with. There is no perfect test to become a doctor that a person has the swine flu.” It has been observed that most people with the swine flu has a set of principles on the fever. It was also common to see dizziness, vomiting and body aches, in addition to the common sneezing, headaches and other symptoms of colds.

If you notice sick and early onset of body aches, vomiting and dizziness should consult their doctor immediately. Although it is highly unlikely that you have the swine flu virus, you should seek medical confirmation just to be safe.

This virus of swine flu outbreak could be a very dangerous epidemic or just another bump in the road. Health officials still trying to figure out exactly where the virus originated, how it is transmitted and why it is mild and sometimes lethal in others. In the half hour. Wash hands, using common sense and be in a high alert to the signs and symptoms of swine influenza virus. See your doctor if any unusual symptoms such as flu.



Flu Remedy

Subhash asked:


Influenza, commonly known as the flu, is an infectious disease of birds and mammals caused by an RNA virus of the family Orthomyxoviridae (the influenza viruses). In people, common symptoms are fever, sore throat, muscle pains, severe headache, coughing, and weakness and fatigue. In more serious cases, influenza causes pneumonia, which can be fatal particularly in young children and the elderly. Sometimes confused with the common cold, influenza is a much more severe disease and caused by a different type of virus. Similarly, the unrelated gastroenteritis is sometimes called “stomach flu” or “24-hour flu”.

Types of influenza virus

The influenza virus is an RNA virus of the family Orthomyxoviridae, which comprises the influenzaviruses, Isavirus and Thogotovirus. There are three types of influenza virus: Influenzavirus A, Influenzavirus B or Influenzavirus C. Influenza A and C infect multiple species, while influenza B almost exclusively infects humans.

The type A viruses are the most virulent human pathogens among the three influenza types and cause the most severe disease. The Influenza A virus can be subdivided into different serotypes based on the antibody response to these viruses.

Influenza B virus is almost exclusively a human pathogen, and is less common than influenza A. The only other animal known to be susceptible to influenza B infection is the seal. This type of influenza mutates at a rate 2-3 times lower than type A and consequently is less genetically diverse, with only one influenza B serotype. As a result of this lack of antigenic diversity, a degree of immunity to influenza B is usually acquired at an early age.

The influenza C virus infects humans and pigs, and can cause severe illness and local epidemics. However, influenza C is less common than the other types and usually seems to cause mild disease in children.

PATHOGENESIS AND DISEASE

Spread

The virus is spread person to person via small particle aerosols (less than 10μm diameter) that can get into respiratory tract. It can also survive for a short time on surfaces and can be spread by this route if the virus is introduced into the before it loses infectivity. The incubation period is short, about 18 to 72 hours.

Virus concentration in nasal and tracheal secretions remains high for 24 to 48 hours after symptoms start and may last longer in children. Titers are usually high and so there are enough infectious virions in a small droplet to start a new infection.

Site of infection

Influenza virus infects the epithelial cells of the respiratory tract. The cells die, in part due to the direct effects of the virus on the cell, and also possibly due to the effects of interferon. Cell death at later times may also result from the actions of cytotoxic T-cells. As a result, the efficiency of ciliary clearance is reduced, leading to impaired function of the mucus elevator; thus there is reduced clearance of infectious agents from the respiratory tract. Gaps in the protective epithelium provide other pathogens with access to other cells; however, viremia is very rare.

Recovery

Interferon may play a role by decreasing virus production. Many of the symptoms of uncomplicated influenza (muscle aches, fatigue, fever) are associated with the efficient induction of interferon. The cell-mediated immune response is important in viral clearance. The antibody response is usually not significant until after virus has been cleared. Repair of the respiratory epithelium begins rapidly, but may take some time to complete.
