Genital Herpes Disease

Category : virus

Start of genital herpes disease after sexual contact with an infected person and symptoms appear in the form of recurrent sores is detected in the clinic. Be sores in glands on the skin and on the penis, where the infection is very painful and continue for a period ranging from 2 - 3 weeks in the absence of treatment. For women, have some problems occurred in the outer regions of the genital organs and in the vagina and cervix symptoms can include difficulty urinating and severe pain, especially when the infection is in the cervical region occurs, burning and pain. Repeat herpes infection increases with the following effects: - Small bruises in the incidence of herpes Other infections, including respiratory sewage small upper Exposure to sunlight (UV) Working Hormone in women (especially before menstruation) Emotional stress Operations performed on the face Dental Surgery Different disease for the first time for recurrence in the size of pimples and the way it collects.

Infection occurs virus type 1 in any area of the body, but mostly you get in the face and on the lips is not a clear pill in the mouth. Repeat virus infection 2 may occur in any area of the body also but mostly occur in the genital area and buttocks. Repeated occurrence of HIV infection in the same areas in the body but not in the same area that was hit the first time infected skin itchy and burning an hour after the injury and accumulate pimples at the center of a red and recovering after 7 to 10 days and without leaving behind spots or marks on the skin and are usually infected person feel comfortable, but there is a high temperature and expanding neighboring lymph roots and although the blisters spreading cluster but sometimes in the form of a line such as measles or herpes blisters, especially when they hit the bottom of the chest and the lumbar region of the body. White spots appear in the incidence of recurrent disease and are more visible on dark skin. Complications: 1 - Eye infection: Herpes causes swollen eyelids. The cause heartburn in the cornea of the eye and swelling and pain in the lymph glands. 2 - Throat infection leading to severe pain. 3 - Sensitivity herpes: Happen for people with allergic children and appears in the form of vesicles scattered in the face accompanied by swelling in the lymph glands and high temperature. 4 - Inflammation of erythematic and allergic erythematic occurs on the hands, arms and lower limbs and appears in the form of reddish spots. 5 - The nervous system: Nerves may be involved in facial herpes virus and the resulting temporary muscle relaxant infected. Proceeded by infection in a time of severe pain due to infection with the herpes virus. Rarely have there in meningitis is associated with disease. 6 - The spread of herpes disease in all the body, particularly those who have a lack of immune and this is dangerous for them.

Treatment: Herpes simplex does not need to treat and as the sun increases the chances of infection but that the use of creams and ointments anti-rays contribute to the alleviation of disease and for injury acute herpes should use anti-virus and include the following drugs that are taken by mouth: - ACICLOVIR - VALCICLOVIR - FAMCICLOVIR Put antiviral for herpes an end to it when it reaches the skin or the mucous membranes, but do not eliminate entirely the virus from its origins in the nerve cells. And can these drugs to stop and prevent the spread of the disease, but one course of treatment is not enough to prevent injury in the future and must be taken courses treatment fully to ensure the injury does not recur in the future. Usually the disease for the first time a simple and lightweight, but they are more serious in the case of recurrence, especially in genital herpes, which is usually more frequently than simple. So you must beware of illicit relationships, which tends to be a major cause of herpes.

What You Should Know About Hepatitis

Category : virus

I have yellow fever doctor, said a patient. How do you know you have yellow fever? The doctor asked. The patient reply "Doc, I have fever and my eyes are yellow."
Here in lies the sea of confusion between Yellow fever, Jaundice and Hepatitis. There seems to be a great deal of confusion about the trio of Yellow fever, Jaundice and Hepatitis. To many people, it would seem that fever along with yellow discoloration of the eyes and mucous membranes and skin (technically called Jaundice) must be yellow fever.
However in the science of medicine, there is a great gulf between these diseases. The yellow fever virus causes yellow fever. A wide range of viruses or toxins on the other hand may cause hepatitis. Both diseases cause inflammation of the liver. An inflamed liver is unable efficiently the breakdown of red blood cells. This results in the accumulation of bilirubin in the blood and connective tissues leading to what is called jaundice. The subject of yellow fever is beyond the scope of this article. Suffice it to say that it is a very deadly ailment with high mortality but totally preventable by an affordable yet very effective yellow fever vaccine which is taken once every ten years.
The specific viruses that cause viral hepatitis include Hepatitis A virus (HAV); Hepatitis B virus(HBV); Hepatitis D virus (HDV) delta agent; Hepatitis E virus (HEV) transmitted in epidemic form in Asia, North Africa and Mexico. There are other viruses that have been implicated in causing hepatitis such as Hepatitis G virus (HGV), SEN-V virus and TT virus (TTV).
The HAV causes the sporadic or epidemic causes of hepatitis. The virus is transmitted or spread through contaminated food and water sources which may therefore lead to outbreaks in large population groups. Its spread is therefore favored by overcrowding, poor sanitation and personal hygiene. The incubation period is usually a few days, 30 days on the average. The illness is usually self-limiting with complete recovery within two weeks. Long lasting infection does not occur. Infections may be severe in adults but may occur in children without any symptoms or indeed ill health. Death from hepatitis A is very rare.
Hepatitis B is usually spread through the inoculation of infected blood or blood products or by sexual intercourse. The virus (HBV) may be found in blood, saliva, semen and vagina fluids in infected persons. A mother who is infected is able to transmit the HBV to the child at the time of delivery. The risk of chronic infection in such cases is very high. HBV tends to occur very commonly in homosexual or gay men and intravenous drug users (IVDUs). Certain groups of people are at higher risk of contracting the infection; doctors, nurses, dentists, blood bank staff, patients and staff of haemodialysis centers etc. Sadly, it takes less blood to transmit HBV than HIV which causes AIDS.
From the time of infection, it takes 6 weeks to 6 months (average 12-14 weeks) for the infected person to become clinically ill. Hepatitis B may also present as very severe form of hepatitis called fulminant hepatitis in about 1% of infected persons. In this group, death may occur in as many as 60% of them. In yet another group, the illness may persist as chronic hepatitis B. In this group, the infection persist for years and then the patient go on to develop liver cirrhosis and liver cancer.
Hepatitis D is a defective virus that is unable to cause hepatitis on its own except in association with HBV. HDV may therefore co-infect a person with HBV or super infected a person with chronic hepatitis. When it occurs concurrently with acute hepatitis or severe chronic hepatitis leading rapidly to cirrhosis.
May be transmitted by blood transfusion, intravenous drug use, sexual contact and from mother to child. Having multiple sexual partners would therefore increase the risk of infection by hepatitis C virus. Incubation period is around 6-7 weeks.
This is a waterborne hepatitis virus. Outbreaks occur in India, Burma, Afghanistan, Algeria and Mexico. The illness is self-limiting with no carrier state. But mortality is usually high in infected in infected pregnant women (up to 10-20%).
This virus has been detected in blood donors, intravenous drug users, haemodialysis patients, haemophiliacs and patients with chronic hepatitis B or C. Hepatitis G does not appear to cause any important liver disease.
The onset of illness may be abrupt or insidious. There is usually a flu-like illness with generalized malaise, fever, muscle aches, joint pains, easy fatigability, sore throat, nasal discharge and loss of appetite, nausea and vomiting. Frequently there is diarrhea, constipation and aversion to smoking for those that smoke. Then as the fever begins to ebb, jaundice sets in 5-10 days. Chill or chillness may occur. The liver is enlarged and painful to touch. The spleen and lymph node may become enlarged also. The diagnosis as to which type of hepatitis is aided through various laboratory tests.
The treatment of hepatitis includes bed rest where applicable. Diet should consist of palatable meals as identified by the patient. Fluid replacement and multivitamin supplements are adjuncts to the treatment. The drug Alpha Interferon has been used in patients with acute hepatitis C and found to reduce the risk of progression to chronic hepatitis C.
In general, the careful handling of needles and the screening of blood before transfusion are useful ways to prevent hepatitis. Hepatitis A may be prevented by vaccination and the use of immunoglobin in people who are in close contact with patient of HAV infection. Hepatitis B has a very potent and effective vaccine, which gives a lifelong protection and requires only intermittent booster doses. Hepatitis B immunoglobulin may also protect or attenuate the severity of illness, if given within seven days of exposure to the HBV.
