Haemorrhagic fever - a group of infectious diseases that disrupt the natural ability of blood to clot. These diseases can also damage the walls of small blood vessels, causing them to become leaky. The resulting internal bleeding that may be of different intensity from the relatively mild to life threatening.

Some types of viral haemorrhagic fever:

• Dengue fever;
• Ebola;
• Lassa fever;
• Marburg fever;
• Yellow fever.

These diseases are more common in tropical regions. In Western countries, they are usually found among those who have recently arrived from the tropics.

Hemorrhagic fever is spread by contact with infected animals, humans or insects. Currently there are no drugs that can be used to cure hemorrhagic fever, there are only a few types of vaccine to protect against these diseases. As long as not to develop more effective vaccines and drugs, the best solution is prevention.

Symptoms

Signs and symptoms of viral hemorrhagic fever depends on its species. Common symptoms are:

• Heat;
• Fatigue;
• Dizziness;
• Muscle aches;
• Weakness.

In severe cases, hemorrhagic fever can cause bleeding in internal organs and under the skin, as well as bleeding from the mouth, eyes and ears.

Symptoms of life-threatening haemorrhagic fever:

• Shock;
• Violation of the nervous system;
• Coma;
• Brad;
• Cramps;
• Renal failure.

When to see a doctor

It is best to seek medical advice before traveling to tropical countries to make some vaccinations and get professional advice on the prevention of diseases. If symptoms of hemorrhagic fevers have appeared after his return from a trip, it is advisable to consult a doctor who specializes in rare infectious diseases. A specialist can quickly identify and cure the disease.

Causes

The viruses that cause hemorrhagic fever, live organisms of different animals and insects - mostly mosquitoes, ticks, rodents and bats.

Some types of hemorrhagic fever can spread from person to person.

Method infection depends on the particular virus. Some of the hemorrhagic fever viruses spread by mosquitoes or ticks. Others are transmitted by contact with blood or semen of infected. Some viruses can be inhaled, is not far from the feces or urine of an infected animal.

Risk factors

Living or traveling in areas where common hemorrhagic fever, is the most obvious risk factor for the disease in this group. Other risk factors include:

• Working with infected hemorrhagic fever;
• Slaughter of infected animals;
• Using dirty needles when injecting drugs;
• Unprotected sex;
• Work outdoors or in buildings with a lot of rats.

Complications

Hemorrhagic fever can cause damage to the brain, eyes, heart, kidneys, liver, lungs, spleen.

In some cases, damage to the Bench are heavy, causing the death of the patient.

Herpes type 3 causes chickenpox in children and shingles Shingles - from simple ailments and brain damage   in adults. After a childhood chickenpox herpes virus type 3 is not removed from the body completely, and hides in the nerve ganglia, where it can remain inactive throughout life. Activated herpes virus with a decrease in immunity.

As it penetrates into the human herpes virus type 3

Herpes simplex virus type 3 is known as varicella zoster virus, it causes chicken pox (varicella) in children and shingles (herpes zoster) in adults who have had chickenpox as a child.

Infection with varicella occurs in childhood in contact with another child suffering from this infection. Varicella zoster virus is transmitted from a patient to a healthy baby by airborne droplets. Sick chicken pox are highly contagious: in contact with the sick child, previously healthy chicken pox, always infected.

After the baby is ill with chicken pox Chickenpox: painful, but not dangerous . The virus "hides in the nerve ganglia and is in an inactive state. Activation of the virus can be caused by any factor leading to decreased immunity. It is any infection, chronic infectious-inflammatory processes, neuroendocrine diseases, injuries, stress. But most often it happens in older people.

Activation of varicella zoster virus leads to the development of herpes zoster Shingles and chickenpox - from the same pathogen . The virus first starts to actively proliferate, and then down the nerve fibers to the skin and cause inflammation on the skin along the nerves. If contact with a sick child, without a history of chickenpox, it is guaranteed to become infected and sick with chickenpox.

Symptoms and treatment of chicken pox

Chickenpox begins a few days after contact with the sick child of the infection (incubation period lasts from 11 to 21 days). In the first day of the disease the patient has malaise, headache, fever. In severe chickenpox temperature may be high. But this disease in children rarely runs hard and if the temperature rises and then to small values.

Starting from the second day on baby's skin rash. Initially, this small, several mm in diameter, round or oval areas of redness and slight swelling. Then, on the surface of the skin area is formed with a transparent vial contents. In severe disease course content can carry a hemorrhagic (bloody) character. A child at this time concerned about severe itching. If at this time to allow him to comb elements eruption possibly a bacterial infection, in which case bubbles becomes purulent content. New elements of the rash appearing gradually, with breaks and coincide with a rise in temperature.

Period rash can last from 2 to 10 days. Then, the bubbles are covered with crusts (also gradually). After falling away crusts on the skin usually does not remain scars. A child sick with chickenpox is contagious from the first day of the disease up to 6 days from the date of occurrence of the last elements of an eruption.

Chickenpox usually requires symptomatic treatment at a high temperature is prescribed antipyretics elements rash lubricated zelenkoj to quickly dry on them and to prevent the ingress of bacterial infections. Antiviral drugs are prescribed only for severe chickenpox.

Symptoms and treatment of herpes zoster

Shingles Ringworm - not only infectious disease   It begins with unpleasant sensations on the skin along the affected nerve - there are pain, numbness or itching. Approximately one day after this on the skin situated along the nerve initially appear redness, swelling and then. Pain and itching at the same time increase. A few days later on the edematous reddened skin appear groups of small bubbles, fusing with each other. Elements of the rash may appear on the new areas of the skin, then they dry up in about a week and covered with crusts.

Most often affects the skin along the intercostal nerves, as well as along the branches of the trigeminal nerve. In general, the disease lasts from 10 days to a month. After falling away crusts can form on the skin pigmentation or, on the contrary, depigmented patches that are a few weeks.

Shingles may be complicated by postherpetic neuralgia - severe pain in the affected nerve, which may remain after the disease for a long time. In order to prevent the development of this complication. Patients in a timely manner prescribed antiviral drugs.

Complications may be as impaired vision (with the defeat of the cornea), hearing, and episodes of severe vertigo (with the defeat of the middle and inner ear).

Herpes type 3 is a mild childhood chickenpox infection, but then settled permanently in the human body and can cause shingles.
