0 Flu symptoms 2013: Chinese bird flu is resistant to drugs

Scientists have discovered a mutation in the new strain of bird flu, showed for the first time in humans in March this year in China, which makes it resistant to key drug without limiting its ability to spread among mammals, Reuters reported, citing published in the journal " Nature Communications ".

The discovery means that unlike seasonal flu strains that often become more difficult transmissible when develop resistance to drugs such as "Tamiflu" to "Roche", the new virus of  bird flu H7N9 has not lost its ability to spread, although developed resistance.





And while it does not strain H7N9 potential to cause a human pandemic, researchers say doctors should be more cautious use of antiviral medications in the treatment of infection with it and be able to use other drugs besides Tamiflu, like Relenza to "GlaxoSmithKline".


"Usually drug resistance damage of viruses, but what surprised us is that in the case of H7N9 resistance does not diminish its ability to spread" says Nicole Bouvier, head of the research team from the hospital "Mount Sinai" in New York.

Experts remind that there is still no evidence of continuing and easy spreading H7N9 strain among people. Published in August scientific analysis, however, offer the most convincing evidence to date that the virus is able to "jump" from person to person and has the potential to cause a human flu pandemic.

In a separate study, experts from the U.S. announced this week that while it is not impossible H7N9 to become easily transmissible from person to person , the virus will have to pass through multiple mutations to achieve it. This means that scientists around the world should continue to monitor it "vigilant" and monitor for signs that developed similar potential .

0 What are the flu symptoms

Learn to identify associated with autorevolezza, the way to protect

The actual flu virus is recognized to distribute very easily through the surroundings inhaled and this is the main reason why any contact with aerosols generates within the onslaught. The virus spreads quickly and hence to prevent an outbreak such as scenario, throughout the world the medical fraternity isolate and treat individuals contaminated with some of the three virus sorts: A, Udem? rket and Chemical substance.

The flu symptoms commonly noticed include fatigue as well as fever related to body as well as headache, severe discomfort sore joints. The condition is also proven to manifest by means of hot and chilly flashes. This provides on ague and also shivering once the fever comes on. The specific resultant cough as well as sore throat due to the trojan being airborne, ushers in an exceedingly sudden loss of desire for food, which usually once again brings on general some weakness and tiredness.

It is possible to see that the virus takes just a single cause element to bring on a number of flu symptoms which are also associated with a whole lot of additional medical maladies. It pays to get over and arrest the particular watering through the eyes as well as a running nasal area or even ear discomfort as quickly as possible. Regarding kids, it is very important avoid the settling within associated with diarrhea. The particular resultant discomforting abdominal pain makes their condition really regrettable. Crucial to remember is the fact that the specific flu virus may be easily overlooked and that this spreads inside the initial week of contraction.




There are a variety associated with remedies at hand that help you in the specific combat and some are actually work from home. Work to private hygiene and being a disinfectant common aspects of interaction go a considerable ways. The outward symptoms could be arrested having lots of rest and a checked diet. Losing desire for food can be best given an increased liquid diet comprising hydrating as well as nourishing fluid consumption and restriction on the intake of any kind of alcoholic beverage. A bout with all the typical cool can mean more things compared to 1 .

The start a common cold could possibly be the consequence of the intake of chilly beverages or even a respiratory system infection because of another health malady or sickness. Still one of the most common manifestations through the flu virus-like infection is also the normal cool. A chilly is recognized to usher in a temperature and the two have a toll on the immune system to actually enable you to get down! Each one of these and the other lead to factors of a common cold are usually surprisingly additionally associated with flu symptoms and signs.

When considering or perhaps deliberating on common cold vs flu symptoms and signs, it is important to keep in mind that the commonalities are just too many! The particular flu virus has existed for a long time right now and hence contracting excellent background in our societies around the world. Still it is vital and also highly critical to note the condition propagates into an outbreak within an issue or days. Like the common chilly, the flu disease too manifests in fever plus body aches. You can find ague as well as fatigue related to both the conditions. The lies in the fact that a common cold are usually treated with home remedies as well as abates along with inhalation and the the consumption of hot fluids; while on the other hand the flu virus requires antibiotics and a shot within severe instances.

It is not even close to wrong to declare which the two immune system weakening conditions occur at the same time. They have also been observed by the portion of the medical related fraternity studying on cold vs flu signs and symptoms that a common cold always comes with the particular onset of flu however it is just not necessary for the chilly in order to result in flu. Instead of treating the observable symptoms like a couple of daily life, it is ital to consider every preventative measure to avoid the particular spread of the condition.

Flu as well as common cold signs and symptoms express by means of a running nose and lack of appetite. Another commonalities range from the starting point of a temperature and general exhaustion. Both the weather is associated with the to the outside exhibition of body soreness, headaches as well as cough, when left disregarded. It is far from uncommon to get a individual with a common cold, like in the situation of influenza, to show signs of feeling sick and vomiting and even diarrhea that will results from disregard. Both the health health problems call for majority, common rehydration, healed steam inhalation and also upgraded private cleanliness.

Flu symptoms could be effectively handled and wiped off the local and work front if handled in time. None of the signs and symptoms need to essentially be neglected, especially in the lighting of understanding that they stick to prolonged tendency of prevalence. It is really worth your time to research and be aware of situation and especially the take factors to be able to challenge the onslaught in the begin. are super easy to detect plus treat as well as hygiene and simple precaution in the common areas of connection and also socialization go a long way to keep the pandemic at bay.

0 Flu symptoms 2013: New flu knocks us just 30 minutes

Only half an hour later we are with temperature and cough .

Epidemiologists revealed that this year we will be attacked by terrible flu with rapid damage to the human body. A few hours after infect 'll be knocked out of bed the usual flu symptoms such as fever, muscle aches and malaise. Experts add that the virus this year will be slightly stronger than last year.


The most dangerous in the new flu strain that spread really fast and actually almost no incubation period. In lower organisms concerned can be broken down within half an hour, and at first did not understand what this is all about.

However, the consequences are severe, because the pain in the throat and whooping cough may continue for weeks, if not timely action is taken. This year's flu strain poses dangers and must go to the GP if misfortune overtake us. As soon as you feel the onset of flu symptoms persist main doctor.

According to experts, self generally lies countless dangers. First is unnecessary for antibiotics that improper dosage can cause serious effects on the kidneys and liver. Furthermore, some of the drugs is quite possible to unlock any allergic reaction, but unfamiliar with the composition of drugs a person can fall right on that.





 Note, however, that a visit to the GP can save you from many unpleasant consequences of flu. Timely medical assistance will help you much more quickly to fight off flu symptoms and healed completely.

1 Flu symptoms 2013: Cold or flu - the difference can be important

Symptoms of the flu and the common cold are similar, but diseases are different

So called  common cold and flu are the most common diseases in the autumn- winter season. Apart from being purely a health issue - they are often confused with each other , as many of their symptoms are the same, their importance is growing more and socially. In many countries, statistics show that 70% of the temporary incapacity of the working age population was due to these seemingly harmless diseases. The tools which are used for their treatment are generally higher than those for the treatment of diabetes, for example. These diseases are not only widespread, but also costly to society, so their prevention and treatment are paying more attention.

The flu and the common cold are different diseases, although occurring in similar ways. Both of respiratory infections, i.e. respiratory tract infections caused by viruses. If common cold is misdiagnosed as the flu, it's not a problem. Rarely, and only in the worst case it may lead to secondary bacterial infections of the ears or sinuses, which are treated with an antibiotic. However, if the flu is misdiagnosed as a common cold and do not take more serious measures, there is a potential risk of serious, even life-threatening complications (such as pneumonia).


Some of the flu symptoms and common cold symptoms are similar, but the two diseases can be distinguished. In contrast to influenza, in which the beginning is suddenly mostly colds gradually - 2-3 days after infection with the virus. The first symptoms are usually irritation and sore throat, followed by sneezing and runny nose with plenty of runny nose, malaise, headache. The temperature most frequently is not raised (at least not substantially ) which also differs in comparison with influenza - with its temperature tends to rise to the higher values. 2-3 days after the beginning of the cold may occur a slight cough. Sometimes the symptoms are more severe in infants and young children - in their temperature can be raised to 39-40 ° C.

Colds usually last between 2 and 7 days. Common cold is a disease which may be caused by more than 200 different viruses - most often they are of the group of the rhinoviruses, but may be from other groups - e.g. coronaviruses, adenoviruses, respiratory syncytial viruses, coxsackie, echo virus and others. Therefore, a variety of agents to the production of a vaccine against cold impossible. To reduce the incidence, it is necessary for people to increase their own defenses and to reduce contact with potential virus carriers.

0 Flu vaccine: Scientists develop new flu vaccine.

 In recent months, U.S. scientists develop new flu vaccine, and their goal is to create a tool to more effectively protect the people of the coming flu pandemic wave.

With the end of summer and the temperature drops, slowly comes and the season of serious disease for which scientists do not stop looking for a cure. Unlike other vaccines, such as hepatitis B, measles, mumps, polio, thie flu vaccine is improving every year.

In the U.S., even now there are proposals by pediatricians children 6 years and older to be vaccinated as soon as the new vaccine becomes available.

According to the Centre for prevention and control of diseases in the U.S. seasonal flu vaccines reduced to 60% risk of becoming ill.

Experts constantly monitor flu viruses to identify those that are most likely to cause sick humans. After the identification, however, it takes at least six months in order to create a vaccine.

The main problem here comes from the long period during which the development of a vaccine takes. Meanwhile, the virus can evolve significantly and then created a vaccine would not be effective enough.

Researchers working on a revolutionary prevention of influenza - a vaccine to protect against all types of influenza viruses, ie seeking "universal flu vaccine". Its development is at an experimental stage, and initial clinical studies suggest that its creation is completely feasible.

Universal vaccine will provide longer protection. It is also planned to be called once like that measles.

What is the prevention of influenza and acute respiratory diseases?
When is the right time to be vaccinated against influenza?

Means of prevention are divided into two major groups - non-specific and specific.

Limit the spread of non-specific causes of respiratory infections such as covering your mouth and nose with a mask or cloth in speaking, sneezing and coughing, frequent replacement and disposal of used masks at designated locations, good personal hygiene, frequent hand washing and rubbing with wipes or disinfectant.

Specific tools include preparations with specific action regarding influenza viruses - flu vaccines and antivirals.

Essential for the prophylaxis of influenza are the current flu vaccines, which are characterized by good tolerability and proven effectiveness.

Vaccination is held in the fall, at least about 1 month before the beginning of the epidemic, as post-vaccination immunity is formed 15-20 days after vaccination. For our latitudes are the most suitable months from October to November, maybe September.

In humans, for which immunization is strongly recommended, but has not been made in time, the vaccine may be administered in December, taking into account the time required for producing immunity - not less than 2 weeks.

Prophylaxis with antiviral drugs is not recommended as standard practice for a number of reasons, including the risk of selecting resistant strains. In any particular case the decision should be made by a specialist.

What should be the prevention of influenza and acute respiratory diseases in at-risk groups?

The only reliable means of protection from flu influenza vaccines. Therefore, they are highly recommended for risk groups.

For people at risk who have not been immunized because of contraindications, no vaccine or other reasons can be applied to prevent antiviral drugs with a prescription.

What other measures can we take to boost immunity to prevent illness during the winter ?

We must not forget that vaccines protect only the included influenza strains, ie from a serious illness, " flu" during the season, and the development of complications. To prevent other causes of acute respiratory disease should not forget some simple rules, often ventilate the premises and hand washing with warm water and soap.

Other measures to reduce exposure to air pollution indoors than solid fuel stoves, smoking, etc..

Full and proper nutrition is also important. It is extremely important to promote breastfeeding of infants for 6 months.

Provision of adequate sleep and rest is also an important measure to improve the overall health and prevention of flu and other respiratory diseases in winter.

1 Stomach flu : Kobuvirus, the new stomach infection

Kobuviruses, new causes of stomach flu

In 1989 . in the county Aihi in Japan in the stool of a person suffering from a stomach flu, was isolated agent called Aihivirus. Yamashita and Takeda authors found that it was 30nm smaller, round, non-enveloped virus that has a positive single-stranded RNA genome of 8280 nucleotides. Aihivirus with newly stomach virus in cattle and swine, formed a new genus Kobuvirus to the picornavirus family .

Increasing also interesting to kobuvirusite rapidly induces numerous studies have found that infection in Asia, Europe and America , both in humans and in animals. Proven so far several different genotypes - to humans, bovine , swine and sheep and possibly rats.
Human kobuvirus a prototype Aihivirusa has 3 variants A, B and C, which are distributed in different continents . Serological survey registers from 70 to 90% of positive blood samples in the elderly . This percentage will get bigger with age. As with other intestinal infections , about half of them pass oligosymptomatic . Clinical picture does not differ much from that of rotaviruses stomach flu. After a short incubation period of up to two days the infection starts with the usual symptoms of stomach flu - transient increase in temperature , malaise, abdominal pain and diarrhea, which is complicated by E. coli . E. coli infection accompanied kobuvirus infection. Rarely appear and respiratory flu symptoms - panting , leaks from the nose , cough, pneumonia , headaches, etc.

Kobuvirus infection has recently become a problem for the human pathology , but still not have developed biologics against her.

Boville kobuvirus is also quite common cause of stomach flu, but because of poorly studied, the distribution is still unclear, and there almost half oligosymptomatic infections occur . Initially infection induces abomazit which reduces appetite , then the virus passes into the small intestine and cause more severe enteritis . Some authors also reported prolonged colitis. Often kobuvirus infection is found in the respiratory tract as bronchopneumonia lesions.Te accompanied regularly by E. coli infections. A subset of infected calves developed respiratory infection catarrhal conjunctivitis . The mortality rate ranges between 5 and 10% , especially if combined with a bacterial infection.

Swine kobuvirus was first isolated in Hungary in 2007, and then in a number of Asian countries - China, Korea , Thailand and Japan. Serological studies show about 90 % positive pigs. Unlike Aihi and Boville kobuvirus, swine Kobuvirus is prone to generalization and viraemias. It is localized not only in the intestine , but can often be found in the body. The virus is excreted in the faeces not only, but also through all the excreta of the sick pig. So it spreads much more intense. Except for diarrhea and stomach flu, the kobuvirus involved in pneumonia with encephalitis and meningitis in pigs, etc.
The Kobuvirus inefection diagnosis is difficult and lengthy. Identification is achieved only through the SGP and then for each genotype using different primers. Clinical picture of kobuvirus infection is not typical and may be confused with several other virus infection.

Despite the significant number of studies , many countries and areas of kobuvirus infection in animals remain unanswered . Spread of infection in many countries is not yet established . Pathogenesis of kobuviruses not only affects the intestinal tract, but also covers a number of other bodies. When this is not yet known which cells and tissues are Predilection for this virus does quiescent conditions , etc.

Immunity against kobuviruses is also unbeaten and appropriate vaccines have not been developed . Since kobuvirus infection becomes relevant especially fever have in this country to begin research vahu this infection .

From the foregoing, it appears that are kobuviruses causative as stomach flu and respiratory diseases such as pneumonia. Among other things, kobuvirus infection usually accompanied with E. coli infection, which further complicates the clinical picture. In some cases the combination is lethal.
Symptoms of kobuvirus infetsiya are standart stomach flu symptoms and in some cases, symptoms of seasonal flu. This makes diagnosis more difficult.

0 Flu symtoms: And this fall, we are not insured by the flu mutation

- What are the forecasts for the expected influenza strains in the new season ? Expect surprises?

Right now it is difficult to make predictions . Influenza viruses have not appeared yet in the Northern Hemisphere.

According to the World Health Organization can expect the emergence of flu strains AH1N1 California, it is possible in some areas to meet and flu strains of AH3N2 Perth , which is known to us from two years ago.

This is somewhat reassuring that the two flu strains have passed through our society and should have some residual immunity in people who have suffered them . On the other hand , as we know , one of the flu virus is very variable , and should not exclude new mutations.

Therefore, to estimate what will be the flu pandemic wave weak or strong by now I can't say.

- A wave of influenza vaccines which will be suitable to use?

If the patient himself has fluctuations what flu vaccine to accept it you should consult your doctor , who advised him most suitable . Putting flu vaccine is a personal choice . In the U.S. the new flu season will be available already and the new quadrivalent flu vaccine . It first includes 4 flu strains - two type A strains and two strains of type B. This provides better protection against flu.

- There are different opinions . Some are opposed to vaccination , others supporters of flu vaccine. Who should be vaccinated?

Experts say that everyone should be vaccinated . This is the only and most secure way to protect not only the flu , but for all diseases for which immunizations are developed . However, there are people who do not need to be vaccinated . Who are you can see in our previous post:
http://stomachflu-symptoms.blogspot.com/2013/09/flu-vaccine-for-you-and-your-children.html

- Which risk groups is recommended to be vaccinated?

Indeed, this is the most important problem. No illusions that flu vaccination should be performed on the entire population. We have no such goals, but to the 2014-2015 season , the need to achieve 75% coverage of vulnerable groups. They are very well defined . These are people over 65 and those with chronic respiratory , heart , internal and metabolic diseases. In fact, this is a large group , it covers the most common diseases. Experience shows that these people must be protected because these complications after suffering flu are most severe , and in some cases fatal.

- What should I do to avoid infection with influenza?

Flu vaccine is the best way. But in life there are different reasons to put it . In this case, always with great skepticism advised to avoid contact with sick . This is impossible . At the beginning of flu epidemics is very large number of people who take the virus. Secondly it is very easy to submit , because becoming airborne . And when sneezing , coughing in public transport , shops and other infection becomes very effective . It is an illusion to say that socially active people can avoid contacts .

- Really treat flu or fight it on foot?

We miss " flu culture " in which at the first flu symptoms - fever , sore throat , coughing , sneezing, we should stop going to work to avoid jeopardizing their colleagues. Unfortunately, these are rare cases.
