Herpes HSV – Causes, Symptoms and Diagnosis
Простой герпес - вирусная инфекция, вызванная одним из вариантов вируса ВПГ. Существует 8 типов вируса герпеса, из которых HSV 1 и HSV 2 являются наиболее распространенными. Вспышка вируса герпеса приводит к герпесу, который может возникнуть на половых органах и ротовой полости по нервным путям. Генитальный герпес относится к генитальной инфекции вирусом простого герпеса. Опоясывающий лишай или опоясывающий лишай вызывается другим вирусом, называемым вирусом Varicella Zoster (VZV). Пациенты с простым герпесом в 3–4 раза чаще заражаются ВИЧ, и эта новая информация делает своевременное лечение орального и генитального герпеса еще более необходимым!
Вирус герпеса обладает сверхъестественной способностью находиться в нервных ганглиях за гематоэнцефалическим барьером в месте, куда иммунная система не может попасть. Это причина, по которой он полностью избежал лечения по западному образцу, поскольку никакое лекарство не может добраться до него, пока это бездействует
Этапы герпетической инфекции
Вирус герпеса имеет тенденцию оставаться бездействующим, прячась в нервных ганглиях и приводя к вспышкам, когда нарушается иммунитет. Стадии герпес-инфекции следующие:
Primary stage: Within 2-8 days of infection, the virus starts off as small, red, painful and fluid filled blisters. These blisters form sores when they break open and eventually dry up.
Latent stage: In this stage there are no symptoms at all as the virus travels to the nerve ganglia.
Shedding stage: Once the virus reaches the nerve ganglia, it starts multiplying and invades body fluids such as semen, vaginal fluids and saliva. These fluids are responsible for shedding or transmitting the virus and hence this stage is known as the “Shedding stage”.
Симптомы герпеса
Oral herpes (Mostly caused by HSV 1) is characterized by red, fluid filled blisters on the lips, mouth and tongue. There is severe pain, tingling, difficulty in eating and swallowing accompanied by fever.
Genital herpes (Mostly caused by HSV 2) is characterized by reddish, fluid filled blisters around the genitals which bursts open to form sores or ulcers. These blisters when present in the genital region result in painful micturation and causes pain while passing stools (if present in the anal region). Other symptoms include headache, bodyache and fever and are prevalent in both men and women.
Please note that both HSV 1 and HSV 2 can cause both genital and oral herpes.
Chicken pox (Caused by Varicella zoster) is characterized by rash, general malaise and low grade fever. In 2-3 days, the rash forms in to vesicular eruption and cause severe itching. After 5-6 days, these eruptions turn into scabs. Rashes appear all over the body except for the palms and soles. Once afflicted with chicken pox, the body develops a natural immunity and the virus remains dormant in the human body.
Cytomegalovirusis a herpetic virus associated with the salivary glands. It affects immune – compromised individuals, such as new born infants, organ transplant recipients and HIV patients. It causes vision problems, diarrhea, infection of the stomach and could even be fatal.
Roseola (caused by Human herpes virus 6 and Human herpes virus 7) is characterized by skin rash and high fever in the pediatric age group. This infection could lead to convulsions in children.
Infectious Mononucleosis (caused by Epstein-Barr virus) is characterized by fever, sore throat, swollen lymph nodes, body-ache, headache and swollen tonsils. A person may remain symptomless even when infected.
Диагностика Герпеса
Your physician may preliminary diagnose Herpes by looking at your sores. He or she may then take a sample of the cells in the sore and send it to a lab for a cell culture. Doctors then may recommend blood tests to confirm the presence of the Virus. Specific tests for blood and fluid from eruptions may be conducted to determine whether the infection is due to HSV1 or HSV2. The most common type of blood test done for the herpes virus are the antibody tests that look for antibodies that your body has created to fight the virus. We always have antibodies for anything we have been infected with. There are now more accurate PCR DNA tests that look for the actual virus in the blood and our Doctors recommend taking PCR DNA tests to find out if the actual virus is left in your blood stream or not.
