11 Flu symptoms 2013: Treatment of flu! Flu epidemic prevention!

The flu is a disease, accompanied mankind for centuries, but it remains a serious medical and social problem in our days. The flu can be manifested in the form of pandemics, epidemics, local outbreaks and isolated cases. Worst flu epidemics caused by type A influenza virus.The flu epidemics occur almost every year, although the severity varies great ly - its distribution is limited to a neighborhood, city or country.

Flu is acute, self-limiting infectious disease that is caused by influenza virus types A, B and C. The temperate climate region, flu epidemics always occur during the winter months. The disease is manifested by toxic infectious syndrome - a sharp deterioration in general health, headache, pain behind the eyeballs, pain in muscles and joints, acute tracheitis, and pulmonary complications leading to high mortality.

Infection is accomplished by transmission of the virus by the secretions from the upper respiratory tract of infected persons. At the beginning of the infection in the secretions of infected concentrate huge amounts of viruses that are transmitted by sneezing, coughing or talking. Only one person is able to infect a wide range of sensitive individuals. This can lead to explosive and snap-onset disease in many people. Man is the primary reservoir and source of infection of influenza. Leading role of Air droplet mechanism in enclosed spaces such as public facilities, vehicles and more. The period of infectiousness in adults is 3 to 5 days after the onset of the disease and up to 7 days in children.

The main factors that determine the risk of disease are: level then its predecessor specific immunity and age of infected them - the final ages are extremely susceptible to infection. With the increased risk are people with sore subject for the cardiovascular and respiratory systems, metabolic diseases, especially diabetes, cancer, immunodeficiency, pregnancy and more.

The incubation period - time from inoculation to first appearance of disease symptoms is from 24 hours to 4-5 days, depending on the infecting dose and the immune status of the organism. The flu infection in adults include a wide spectrum of manifestations of asymptomatic infection to primary viral pneumonia, which can be fatal.

Despite exist in the public domain opinion about "atypical forms" of influenza, the clinical picture of flu is very typical stereotype. Onset is sudden, with severe general condition, headache, chills, pain in muscles and joints, loss of appetite. The main feature of influenza is the sharp rise in temperature to 38-40 degrees. She remained at high levels by the second or third day began to rapidly decline. The second day appear catarrhal symptoms: nasal nose, leaking serous discharge from the nose, sneezing, irritation and discomfort in the throat. There may be redness of the mucous membranes of the eyes and hard tears. There is a dry irritating cough. In the neck detected single enlarged lymph nodes. In auscultation and radiography of the lungs Absent abnormalities. Typically, a temperature decrease of the symptoms of the respiratory tract are exacerbated. Cough gradually becomes moist and productive.

In people over the age of 65 the temperature was increased in low-grade values (slightly elevated - br), respiratory symptoms are mild, often noted blurred consciousness. After normalization of temperature and symptom recovery runs from 1 to 2 weeks with malaise, tiredness and cough.

In children, the course is similar to that in adults, but is also characterized by certain features. The temperature normally is higher and may be accompanied by convulsions. Higher the incidence of otitis media, croup (viral infection of the respiratory tract in children 3 months to 3 years, with ongoing barking cough, hoarse or raspy voice, loud, rapid and labored breathing, etc.. B. River ), pneumonia, and myositis. (Myositis in children covers the muscles of the lower leg and is expressed in much pain when walking.) Influenza predisposes to secondary bacterial pneumonia and exacerbate pre-existing asthma. In children under 3 years are common dyspeptic events, such as nausea, vomiting, abdominal pain. There may be multiple diarrheal stools.

In infancy the disease is particularly high temperatures, severely impaired general condition in the absence of local signs and can be fatal.

In the second and third trimester of pregnancy have an increased risk of fatal ending influenza infection to the fetus, since the virus is not isolated from it.

Influenza virus type B gives the same spectrum of diseases influenza A, but the incidence of serious and complex shapes is 4-fold lower. Typical events are gastrointestinal - nausea, vomiting, diarrhea, and myositis. Infection with Influenza occurs in small epidemics and affects mostly school and adolescence.

Influenza C occurs as sporadic cases with mild catarrhal manifestations (inflammation of the mucous membranes of the respiratory tract)

Complications of influenza are mainly from the lungs, and less of the nervous system. They are more common in patients of advanced age.

The diagnosis of flu made on the basis of data on the seasonal incidence, clinical features of acute onset with marked intoksikotsionen and subsequent catarrhal syndrome. The final placement is by virological investigations. In the acute period of the disease (the third day) materials from patients for research pharyngeal and / or nasal swabs and washes, and tracheal or bronchial aspirates. They demonstrate any naspetsifichni influenza antigens within minutes and hours. (For virus isolation in eggs and cell culture and subsequent identification take 1 to 2 weeks.) Used different serological methods for the detection of antibodies to influenza virus in two consecutive serum samples taken. Differential diagnosis is necessary in the first place with the other acute respiratory viral diseases due to increased seasonal incidence during the cold months of the year, the presence of intoxication and catarrhal symptoms.

Treatment of uncomplicated forms of influenza are appointed antipyretics, analgesics or nonsteroidal anti-inflammatory drugs. In persistent cough include antitussive. For the treatment of flu A are known four antiviral agents: amantadine, rimantadine, and neuraminidase inhibitors (zanamivir, oseltamivir). To exhibit therapeutic activity, need to be employed in the first 24 to 48 hours from the onset of the disease. Their therapeutic effect, comprising: a mild course of the disease, reduction in the duration of the symptoms, reducing the incidence of complications and duration of the radiation navirusa. The preparations can be used for prophylaxis of influenza in naive patients during the flu epidemic or when it has been shown that the population circulating virus strain which is not included in the panel for flu vaccines.

Primary prophylactic measure against influenza has been the use of flu vaccines. All of which are developed after isolation and precise selection of circulating the season influenza A and B viruses, which is supposed to cause the disease in the following season. Vaccines decrease in greater severity than the incidence of infection. It is essential to familiarize the public and health care personnel with the basic principles of personal hygiene and the risk of transmission of influenza virus: coughing and sneezing and by contact with contaminated hands mucosa. Chemoprophylaxis with antivirals has a high efficiency - 80%.

1 Flu symptoms 2013: Summer Flu - Particularly at risk are children.

Summer Flu

* The impact of the summer flu are no less dangerous. Particularly at risk are children.

Most often in people's minds the word flu is associated with winter, aching joints and muscles, irritating cough, nausea and dizziness. Besides the usual flu viruses during the cold time of year there are a separate group of flu strains that cause diseases from May to October. Unlike winter flu attacking respiratory and urinary system

summer viruses damaging mainly the gastrointestinal tract.

Consequences of the summer flu the body are no less dangerous than other types of influenza viruses.

Flu Symptoms

Warning signs of the development of flu infection is manifested in several symptoms.
Mild sore throat, fever up to thirty-nine degrees, but the main complaints come from the digestive system.
Start colic in the gastrointestinal tract, passing mucous stools repeatedly during the day, vomiting of gastric juice. Hence the danger of the loss of the mineral salts and the dehydration of the body, accumulation of toxins from the activity of viruses.

Chronically ill people can get tosevere intoxication, peritonitis, volvulus, occurrence of chronic colitis.

Especially endangered group young children are rapidly dried, and their immune system is not yet formed as in adults.

Flu Prevention

To prevent viral diseases in the summer is not enough respect for good personal hygiene and healthy food. The main factor for the stop any infection is the health of the immune system.And something that can not be achieved with the drugs or the release of major errors in the diet.

Consequences of the summer flu are not only for digestive system are affected and joint system, the endocrine system and the formation of lasting immunodeficiency. This is at full strength for children under ten years of age and older with long-term chronic diseases. The basic operation for the treatment and prophylaxis of viral diseases is directed to the stabilization of internal reserves of the organism.

In conclusion:

What causes summer flu?

Summer flu is a viral infection that is caused by influenza viruses A and B.
Flu symptoms were pain, chills, fever, and cough or throat irritation. Influenza is common during the winter months, but you can catch the flu at any time of year, even in summer.

Symptoms of summer flu


Complications of summer flu

In rare cases may develop complications of the summer flu and ear infections or pneumonia.

0 Bird flu H7N9 attacked again, warning of a pandemic!

avian flu H7N9

Syndicate mail alert these days doctors in France for the presence of an alleged case of the deadly bird flu H7N9. The new bird flu strain was detected for the first time in China in late March, and his victims are now 35. Most of them are from the area of ​​Shanghai. Experts are concerned about the speed with which the virus is spreading faster than its mutation and the possibility of infection has to be passed from person to person.

According to the World Health Organization H7N9 is one of the most lethal influenza viruses can stand on the threshold of a new global pandemic. Mankind has no immunity to the new strain of flu in more than 90% of the clinical forms of the disease are severe, and scientists have not been able to invent a vaccine.

Virus spread are increased

One of the most insidious features of the new avian flu strain that infects birds without Symptoms. That is, without making them sick. This complicates the control of the spread of the virus which can survive for several days in the environment. Scientists are still hoping most worrying scenario - the transmission of the new strain from one person to pass us by. The method of transmission of infection to humans, however, lies a mystery.

If birds are the ultimate source of the infection, how do we explain the fact that almost half of those infected before they get sick from avian flu, had no contact with poultry? Such is the case with a patient ill from H7N9 in Taiwan. Virologists studying the cases of infection within a family. To solve the mystery of the new avian flu H7N9, the World Health Organization launched an investigation in China. Peyris Malik, Professor of Virology and Medical Sciences at University of Hong Kong, suggesting that the wide range of deadly virus responsible merchants to help carry the virus between poultry farms and shops.

In 2002, just infected bird cages have been the key factor in the outbreak of the H5N1 strain in Hong Kong, highlights Peyris. It is quite possible that such traffic is one of the major risk factors for the dissemination and the new virus. What is worrying is that last week the dangerous strain was first discovered in a bird purchased on the wholesale market in Dongguan, Guangdong Province, 100 kilometers from Hong Kong. This, according Peyris perhaps the moment when China and Asia need to review practices in poultry-farming, and Hong Kong to serve them as a model of biosecurity. In the first place should be closed wet markets. It is urgent and large-scale testing of blood samples to look for "silent infections." This will help to answer the question can now H7N9 virus of bird flu is transmitted from person to person.

The study will clarify and whether infected develop only mild symptoms - cases they have not hitherto been discovered and reported. If it is proved that the cause of the virus in poultry, getting rid of the deadly H7N9 strain will not be easy because they are very popular food in the world. But experts fear that the new flu strain can now infect other animals, including pigs, make spreading more widely. Because if H7N9 came out of the continent of Asia, can create more problems than his kinsman H5N1, which failed to evolve, but for now over 63 countries, leaving hundreds of thousands of dead birds behind and took hundreds of lives.

Probability of transmission of the new virus of bird flu, H7N9, from person to person, it is much more!

According to experts, the likelihood of transmission of the new virus of bird flu H7N9, from person to person, it is much larger than the other strains, ITAR-TASS reported.
Experts from the World Health Organization in China compared with other H7N9 strains and have concluded that it spreads faster than them. Its susceptibility to mutation greatly increases the risk of illness. The features of the new virus are not fully explored, scientists warn the authorities in Beijing to preserve the condition of caution.

0 Stomach flu treatment. Viral, bacterial and parasitic gastroenteritis.

stomach flu treatment

What is gastroenteritis?

Gastroenteritis also known as stomach flu is a gastrointestinal infection caused by viruses, bacteria or parasites. Stomach flu is a disease associated primarily with hygiene and sanitary conditions of living, dining and living.

Stomach Flu Symptoms

The most characteristic stomach flu symptom is diarrhea preceded by abdominal pain. Apart from this characteristic symptom, the disease can be expressed more in the presence of:
- Temperature
- Lack of appetite
- Nausea
- Vomiting
- Weight loss and dehydration
- Mucus or blood in stool
Usually, viral gastroenteritis lasts a few days and goes away by itself.
More severe, dangerous and time consuming are bacterial and parasitic gastroenteritis, which are more common and known as "food poisoning" because the most common sources of infection are consumption of food and water.
The stomach flu is an acute infectious disease care so that other people will not become infected after contact with the patient must be related to the maintenance of good personal hygiene and sanitation.

Stomach flu treatment:

Viral gastroenteritis usually do not need treatment because the body itself solves the problem for a few days.
Situation for bacterial gastroenteritis is a little different because disease-causing bacteria are more virulent than viruses and can cause more problems and complications. In addition, in people with weakened or compromised immune system bacteria can scatter to other parts of the body and cause an even life-threatening infection known as "sepsis." Therefore, very often it is reasonable in the case of a bacterial infection using the appropriate antibiotic to eliminate the risk of spreading the infection or growth.
Usually, the main focus is on stomach flu symptoms treatment, ie addressing and eliminating the symptoms. Firstly these are antidiarrheals means to mitigate or stop the disorder and drinking plenty of fluids to compensate for their loss due to diarrhea. Are suitable for clear, salted soups, but because the body loses fluids important sodium and potassium ions and their loss must be compensated. For the duration of the disorder to avoid carbonated beverages, milk and sweets because they reinforce diarrhea.
