What is really true and what are myths? Here is the explanation of the ten virgin mysteries.
Vaccines are not dangerous, but they have side effects like any other medical treatment
Myth 1: Influenza is just a hard treat with cold
Colds and flu have certain symptoms in common, and in lighter cases the flu may resemble colds. But the flu is a more serious disease, and is due to a completely different family of viruses.
Symptoms of cold: Runny or tight nose, irritation and sneezing, and often red, runny eyes, light pressure over the sinuses, but no significant temperature increase or general feeling of disease.
Influenza Symptoms: High fever and a massive general impact on the body are often part of the flu symptoms, which also include cold throats, muscle aches, headaches, dry coughs, throat and chest pain and general discomfort, possibly nausea and vomit.
In more severe cases, flu can lead to pneumonia, which can be dangerous especially for young children and elderly.

Myth 2: You can get flu of influenza vaccine
Exercise against colds?
Crush the flu
– No, no and again no, says Professor of Experimental Virology, Allan Randrup Thomsen, for science. dk.
– It is not living virus in a flu vaccine. You have broken and twisted the virus into small pieces, so it’s completely dead. In addition, the vaccine does not contain whole viruses, but selected components that the immune system is able to recognize and then make protection against. There may be some symptoms after the vaccine syringe.
– For example, it is quite normal to swell and get sore in an area around the place where the vaccine was put and, in rare cases, also mild fever. It’s actually a good sign. It shows that the immune system is updating itself, “says Thomsen.
Myth 3: You only transmit infection as long as you cough and sneeze
You can infect others as long as you have the virus in your body, but the amount of virus you divorce is of course the greatest and you spread the most when you cough and sneeze.
– But you can distinguish both flu and colds without having symptoms. Usually, the first flu symptoms appear 3-4 days after infected with influenza virus. In the case of colds, it is about one to three days. And in this period you are also contagious, says Professor of Experimental Virology, Allan Randrup Thomsen.
– Typically, one can also infect others a few days after the symptoms have disappeared. So, in fact, it’s an argument that, in principle, you should stay a day longer at home in sick leave than the symptoms last. And the “heroes” of the workplace, who are sick and bad at the office, even if they have symptoms, are in fact the largest smokers, and they should be home for the sake of others, says Thomsen.

Myth 4: I have just had flu, I do not need to vaccinate until about a year
– Each year’s influenza vaccine contains protection against two to three different influenza viruses, says Professor of Experimental Virology, Allan Randrup Thomsen.
If you have had a type A flu, you may still get a B type next time, and then you will not be protected if you have not taken a vaccine.
Myth 5: Antibiotics and vitamin C can prevent or treat colds and flu
– Antibiotics fight bacteria and therefore have no effect on viral infections, says Professor of Experimental Virology, Allan Randrup Thomsen.
– Vitamin C can not overdose from colds, says lecturer in infection immunology, Jan Pravsgaard Christensen.
– But there is an effective remedy for influenza – the so-called neuraminidase inhibitors, such as tamiflu. It is only important that you start taking the medicine as soon as possible after you have been infected with influenza virus.
Myth 6: Vaccines are dangerous
– Vaccines are not dangerous, but they have side effects like any other medical treatment, Allan Randrup Thomsen strikes.
– The side effects may appear more clearly in vaccines because we take a healthy person and treat it. On the other hand, if a sick patient receives a treatment, he or she may be more likely to accept certain side effects.
– Comparisons we side effects of the vaccine with the natural variation of the disease, will no vaccines near danger level of the natural infection.

Myth 7: You must be vaccinated before December, otherwise the vaccination will not work
Ideally, you should vaccinate yourself in October or November before the flu season starts. It takes some time before the body is protected by the vaccine.
– But that does not mean it’s too late to be vaccinated in December or January for that matter. You should only be aware that it takes some time to get the vaccination until it works and during that time you are still vulnerable, “says Virologist Allan Randrup Thomsen.
Myth 8: Influenza vaccine is only for elderly people and people with weak immune systems
– Elderly and children are the primary target group, because they get the most sick and can die, says Allan Randrup Thomsen.
– But then it comes to the group of people who deal with weak and sick people, they should also be vaccinated. Nurses, doctors, at least healthcare professionals, so they do not become infected with vulnerable patients.
There are also healthy breeders.
– They are not sick, go to work every day and risk to infect others. Or they are of the superfluous type who will not expel guards and “deceive” the patients and go to work even if they have flu, “says Jan Pravsgaard Christensen.
Myth 9: You only get cold and get flu in the winter months
It’s most likely to get the flu or to get cold in the winter months. One of the reasons is that we are more indoors, but also that virus survives easier in cold.
Influenza and colds are often contaminated by a person coughing or sneezing in the hand, and then the virus passes by taking another person in hand, on a door handle or an ATM. Virus can survive longer in winter than in summer.
But it’s possible to get cold or get flu in the summer too.
Myth 10: You do not get the cold to freeze
– The primary path of cold virus into the body is through the nose, explains Allan Randrup Thomsen.
– At the same time, it is important to remember that the immune system’s defense cells, such as the antibodies, penetrate the body through the bloodstream.
– An American survey has shown that if you cool your feet, it presents a greater risk of developing cold symptoms. The explanation may be that cooling can lead to lower blood flow in the nasal mucosa. The cold causes the bloodstream to contract and the blood is pulled away from extremities such as hands, ears and noses to protect and warm the brain and heart. But less blood in the nasal mucosa means fewer immune cells to patrol and slow down a possible invasive cold virus.
It’s not the cold as such, which gives you cold symptoms, but if the virus is about to invade you, you’re more vulnerable if you freeze.
