Here are 7 questions. Tick the answer you think is correct as. Next question comes up first when you have answered correctly. By following the link in question text, you can find detailed information on the issue.
One of the allegations of viruses is right, what? Virus is considered the smallest living preparation h organism A cell infected by viruses create new viruses Scarlet fever is caused by viruses Antibiotics can cure most viral infections
Viruses can not subsist and propagate their own help, they need a host to do this. Most will not count viruses living organisms. Viruses and bacteria are the predominant causes of infections. Virus causes damage in that they acquires control of body cells and uses the cell constituents to multiply and create thousands of new viruses. During this process, the cells are broken and new cells are invaded. Just a few viral infections can be treated with antiviral drugs. Antibiotics have no effect on viral infections, they treat only bacterial infections. A viral infection can weaken the body (immune system) enough that it is affected by a bacterial infection (called a secondary infection), and if that happens, antibiotics can be relevant.
Why are not immune to colds? One can not become immune to viruses immune response is too slow to prevent preparation h virus infections Many different viruses can cause colds immune response against viruses items 3-4 months
Colds caused by a virus that attacks the nose and pharynx. Different preparation h viruses preparation h can cause upper respiratory tract infection, but often it is called a rhinovirus. Among the various viruses that can cause colds, there are hundreds of subtypes. The large diversity of viruses that colds can occur throughout life. Although you develop immunity against the virus that has made you sick, there will still be many other viruses that can give you a cold.
Chickenpox is a childhood disease with fever and rash caused by varicella virus (varicella). Chickenpox is the most contagious of all childhood diseases. Most children get chickenpox, and the disease occurs worldwide. 40% infected before age 4 and 40% in 4-8 years age. The disease also occurs in adults. At the age of 30 years is 98% of the population immune, but many do not remember that they have had chickenpox (not all develop preparation h symptoms of infection, especially if they are affected in early childhood).
Shingles is due to the same virus that gives chickenpox preparation h in children, the varicella zoster virus (VZV). One must have had chickenpox first to get shingles. Following the outbreak of chickenpox in childhood, the virus infects the nerves that go out to the skin. The virus is transported preparation h along the nerve and settles preparation h in nerve nodules located near the spinal cord. Here lies the virus for years, without giving any symptoms. preparation h When one grows older, the virus can suddenly preparation h begin to multiply, and it travels along nerve onto the skin again. Here starts a powerful inflammation that produces pain, rash and general symptoms (here you can read more about shingles). As the inflammation is associated preparation h with a particular nerve, the affected skin area fairly clearly delineated and will normally only frame on half side of the body (right or left).
Ebolavirus preparation h origin is unknown. It is a so-called filovirus. One assumes that it is found naturally in the rainforest in Africa and Asia, and that man is not natural reservoir. There is little evidence preparation h that the virus is spread via airborne infection. Infection occurs through direct contact with blood, semen or other body fluids, ev. contact with internal organs from infected persons. There are no reported cases in Norway. The infection is feared with good reason. A typical course is suddenly fever, fatigue preparation h and muscle aches. Gradually also headache and sore throat. This is followed by vomiting, diarrhea, rash, and failing liver and kidney function. Later occurs both internal and external bleeding followed preparation h by shock and pronounced bleeding (DIC). Less than half of those who develop symptoms of infection with Ebola survive.
Gastroenteritis is for most a harmless condition and goes over in 3-7 days. A possible problem in handling flu is still drying. A loser much fluid through both vomiting and diarrhea, in addition one has less desire of both food and drink during illness. Drying can cause serious problems, especially in children under 2 years of age and among older people. To avoid dehydration, it is important to drink a lot. Small and dark urine is a sign of fluid deficiency. In young children can desiccation also be manifest when the child becomes limp and dull, possibly irritable.
Three of the options below is correct preparation h regarding mononucleosis, preparation h which option is WRONG? preparation h The chance of developing the disease several times is great It is caused a herpesvirus Half of the adult population has had mononucleosis Some antibiotics can cause a rash of this disease preparation h
Kissing disease is also called infectious mononucleosis. It is an infection with a virus called Ep
