Viruses exist everywhere from the air, earth, to animal bodies. These tiny organisms have diameters that measure in nanometers. Quite a good number of viruses live how to do countdowns on iphone human bodies. Most viruses are harmless to the body because the immune system produces antibodies that work against the viruses seeking to destroy them. A harmful virus could be opportunistic. This means that when the human immune system gets weak due to certain reasons, the virus takes advantage of the situation to become a pathogen.
Sometimes the virus and the immune system often lie in a balanced system. For example, in the what information do isp providers keep lies the BK polyomavirus.

To diseases caused by viruses, they are known as diseases or viral infections. These are caused by infectious agents that live and propagate into living cell units. Flu virus. These infectious agents are known as viruses. A virus can be defined as a microscopic pathogen, much smaller than most bacteria Mandal, They consist of a coating of protein and genetic material inside. Viruses are the most numerous biological structures on the planet, being very dangerous for humans because they can cause infections and diseases of all kinds.
A disease does not always appear when a virus is acquired, because the immune system may be able to fight it. However, some viruses can attack certain cells, multiply within them and propagate. Cells of the immune system attacking viruses. For the generality of viral diseases, treatments only improve symptoms while the immune system attacks the virus. Antibiotics do not work for viral infections. There are antiviral medicines to deal with and vaccines can make it more difficult to spread.
Viruses can remain in the cell without damaging it, making it a carrier. The patient appears healthy, but infection may occur after a latency period Medline Plus, In the organism it can give a form of immunity that lasts a long time, because the virus enters, the organism confronts it and it remembers producing specific antibodies against him avoiding to re-acquire it.
It is a disease caused by the virus of homonymous name Ebola. It is considered one of the most contagious viral and infectious diseases in the world. Its spread occurs both in animal species and in humans. Its most important symptom is the hemorrhagic fever it generates. This condition leads to muscle aches, physical exhaustion, headache intense. Its transmission is given by having direct contact with any type of fluid derived from an individual carrying the virus. These fluids include discharge, sweating, vomiting, or urine.
Unlike other diseases, its contagion can not be prevented by means of vaccination and the preventive alternatives available today are purely experimental. Gastroenteritis is known as the"stomach flu. You may be given the alternate name of rotavirus or Norwalk virus. Its spread occurs when an individual or group of individuals consume the same food or drink contaminated by the microorganisms that cause the virus. The first symptoms of the disease appear almost immediately and are nausea, vomiting and diarrhea.
Gastroenteritis caused by the transmission of a virus is common in people of all ages. Also, it can be divided into several types including rotavirus, norovirus, enteric adenovirus and astrovirus. This disease can be treated by preventing dehydration by increasing the consumption of beverages rich in salts and minerals. Dengue disease is named after the virus that causes it dengue.
It is one of the most common viral diseases in the world, infecting more than million people annually. Like yellow fever, it is transmitted through the bite of the Aedes Aegypti fly. It feeds on the blood of a person infected and then passes the virus to a healthy person through his sting. The Aedes Aegypti fly reproduces in places where there is stagnant water, depositing its eggs in the walls or edges of these wells of water. The virus can also be transmitted by consuming water contaminated with the eggs of the fly.
Among the most common symptoms of dengue are lymph node growth, severe muscle pain, fever, joint pain and the occasional appearance of skin rashes. Like other viral diseases, dengue can be prevented by administering a single-dose vaccine in patients between 0 and 12 months of age.

The Human Immunodeficiency Virus or HIV attacks the immune system, making people susceptible to life-threatening infections. AIDS or Acquired Immune Deficiency Syndrome is the period of HIV infection, where there are low levels of defenses and the onset of rare infections called opportunistic infections, which arise when the immune defenses of the HIV-infected person are few.
Normally, a healthy organism could fight against them, but an infected organism is unable to defend itself. This virus is transmitted through unprotected sex, by sharing syringes or any object that may have been in contact with infected blood. It can also be spread by a mother to her baby, either during the lactation period or at the time of delivery. It is prevented by having sex with protection, always using sterile material for perforations or tattoos and avoiding sharing of syringes if injected drugs are used Infosida, Today, thanks to antiretroviral treatment, an infected mother can have pregnancy and childbirth without the risk of the baby being infected.
Viral hepatitis is inflammation of the liver caused by any of the five hepatitis viruses A, B, C, D and E that can be transmitted in different ways. Hepatitis A and E are transmitted by contaminated water and food, hepatitis B by blood and other unsafe body fluids, and hepatitis C by infected blood. Hepatitis D virus infections only occur in people with hepatitis B.
All these viruses cause acute hepatitis, which causes fatigue, fever, jaundice, and decreased appetite. With proper treatment, a large percentage of people recover completely. In addition, hepatitis B and C virus infections can become chronic and cause liver cancer or cirrhosis. Measures to prevent hepatitis are not enough, A and E can be avoided by consuming safe water and food. The A, B and E with vaccines. The C, is of blood transmission so you have to take care that the material of injections and transfusions is sterile and safe.
The human papilloma virus HPV is a group of more than types of virus related to each other. These viruses cause warts on different parts of the body and about 40 of them affect the genital area. They spread through sexual contact with an infected person. Some of these viruses can lead to cancer.

These infections are very common and any sexually active person can get it, especially if you have many sexual partners. Many people outgrow HPV infections in two or three years without developing a cancer, other infections can persist for many years and others can cause cell changes that, if left untreated, can become cancerous.
Thanks to cytology, women can opportunely detect changes in the cervix that could become cancerous. The use of condoms and vaccines can prevent the risk of contracting and transmitting HPV. It is a viral disease known as kiss disease.
It is caused by the virus Epstein-Barr EBV , however, can also be caused by the cytomegalovirus that is transmitted orally and causes inflammation of the lymph nodes with fever, general weakness, pharyngitis and headaches.
It attacks mainly adolescents and young people. It is almost always a benign process in which the response of the body's defenses is basic. It is spread by contact with kitchen utensils, coughs, sneezes, or kisses of an infected person, or by a blood transfusion. There is no concrete and effective treatment against this disease, therefore only medicines that relieve the discomforts it causes are used. General culture History biology Other phrases Literature.
