Soon, flu viruses will circulate extensively again. The difficult thing about it: you do not know what order and composition they appear and how much they differ from the previous year. As the current vaccine is always based on experiences in the previous year, speculation is always about their development. The stresses of Influenzagruppe B. are particularly difficult for assessment.
"It's hard to predict which specific types of flu B will appear in a year. Flu A group has always been the same stress, H3N2 and H1N1, in recent years, but their time was different," he explained Günter Weiss, director of the Department of Internal Medicine II in Innsbruck.
Sometimes a virus changes so low that the biological memory can identify and fight the virus. Sometimes a virus is changing more and the immune response is getting worse. Weiss: "The problem with the vaccine is that it lies behind a year, so to talk."
Another restriction is the effect of the age of the vaccine. "In children, we have 90 per cent of vaccination, in the elderly about 30 percent," explains Weiss. Good news: If people become ill despite the vaccination, flu is less serious.
So who should be vaccinated against the flu? The expert recommends the vaccination of chronic and elderly people. It is also important that members of serious and chronic people are vaccinated. Weiss: "One is trying to build some herd immunity around these people." It is also suggested that people in medical occupations are vaccinated regularly. Here you will decide to protect yourself, the family and the nutrition.
Finally but not least, parents repeatedly ask if they should have a child's vaccine against the flu. Children with chronic conditions, such as asthma, advise Weiss to get vaccinated. Otherwise, it really looks at the advantages and disadvantages. For example, flu in children can sometimes be severe. Or the parents can not accept that two children of care need their child at home. "You have to offer a talk to parents about risks and benefits," said the expert.
From December to April, flu viruses will be transferred again. Flu is still a serious illness. Where the start of the disease usually starts suddenly with minor violence, with joint pain and muscle and coughing each other. Slips and high fever, even up to 40 degrees, come to it. By contrast, the thermometer rises in a flu infection from 37 to 37.5 degrees, with the nose, the tiredness, the neck and the head head being infected with the infection this. Every year about 5-10 percent of the population in the Tyrol suffers from severe flu.
Flu diseases in this country disappear. "In order to ensure effective security, the average injection rate must be 80 percent, we are currently between 10 and 15 percent. For people at higher risk of having flu or death , a higher rate of vaccination would be important, "comes to the Weiss collection. So every population of the population needs to be moved.
The development in science is also exciting. As Weiss says, a lot of research is taking place "how often you can have flu in life or if there is a permanent immunity. And you also want to know how often you should get vaccinated, annually or perhaps every year "Although it is a common disease, there are still many unknown ones.
… ban the pathogens
Virus and Cho protection wash hands several times a day. Moderate sports (do not outweigh) and also a balanced diet for winter. Smoking absence protects the mucus membranes in the neck.
… Thousands of flu patients
Each year in our latitudes, there are five to ten percent of flu in the cold-term population contract. More than 100 people are hospitalized every term in the Innsbruck Clinic as a result of severe flu.
… a flu epidemic during the holidays
Flu waves occur from December to April. Possible reason: In cold weather, people are more likely of it and they like to move with each other. In the tropics, flu occurs every year, in the south hemisphere during the summer months.
When you are tired, the thief responsible for the infection spreads within a radius of one to two meters. Pathogens are also transmitted by speaking, hawking and touching the doorknobs.
… flu in comparison
Flu patients are believed to infect three to five other people. Measles for measles B. the frequency of infection is higher. Here one expects a sick person infecting 13 to 20 other people.
