Q: 

What is the most interesting fact about ebola?

A: The most interesting thing about ebola is that the virus causes a hemorrhagic fever. This is in part due to the virus but also due to our own bodies immune response to the virus. Chemicals our bodies white blood cells produce are largely responsible for the bleeding. I did a paper on this years ago. I remember that it basically turns your insides into a liquidy mess. You bleed from everywhere cuz it breaks down cell walls. Also, in late stages, it can cause epileptic-like flailing and violent shaking, which spurts blood and mucus everywhere, infecting those around them. Stay out of Africa! The most interesting thing is that it is a lethal disease. The infected person vomits black bile and blood. Hope that helps! It is a wicked little virus! And very efficient, too! Probably the most...


Q: 

HIV conducting tests?

A: Hi there, An HIV trial shows if someone is infected with HIV, the virus that attacks the body''s immune system and cause acquired immune not as much as syndrome, or what is more commonly known as AIDS. There are several different test that can be used to determine if you are carrying the HIV virus. The first test developed is still the most frequently used for the initial detection of HIV infection: the enzyme-linked immunosorbent assay or as it''s more commonly set, the ELISA or EIA. The ELISA is usually done by drawing blood, usually from a vein surrounded by the arm. The process is occasionally slightly uncomfortable. For most race, it is not particularly bumpy and the blood draw is...


Q: 

How does gonorrhea attack your body?

A: FAIL Symptoms of gonorrhea in women As many as 80% of women with gonorrhea show no symptoms. If present, symptoms may include the following: bleeding between menstrual periods chronic abdominal pain painful urination vaginal discharge, often cloudy and yellow in the case of oral infection, there may be no symptoms or only a sore throat. anal infection may cause rectal itching or discharge. Because women often do not show any symptoms, complications are more likely to occur as the disease progresses. The most common complication is pelvic inflammatory disease (PID). PID can occur in up to 40% of women with gonorrhea and may result in damage to the fallopian tubes, a pregnancy developing outside the uterus (ectopic pregnancy), or sterility. If an infected woman is pregnant,...


Q: 

  After my husband and I had been together for 6 years I got pregnant and wastested for chlamydia, i had had no othersexual partners and as far as i know hehadn''t either, is there any way you can get chlamydia other than throughsexualcontact and can the i

A: Hi! Thanks for the question on the forum. I can understand your concern regarding the reports. Chlamydia istransmitted only during vaginal, anal, or oral sex. Chlamydia can also be passed from an infected mother toher baby during vaginal childbirth. There is no other route of transmission of Chlamydia. So if you aretesting positive and your husband is not either your test is false positive or your husband?s is falsenegative, considering you both have not had other partners. It is possible to get false positive or falsenegative results with the standard tests for Chlamydia. Hence it would be wise to repeat the tests (may not bea good option as standart tests are coming positive). Else you can opt for specific tests for Chlamydia whichinclude Nucleic acid amplification tests (NAAT, to find...


Q: 

False-positive HIV test?

A: Dear Reader, Getting a false positive HIV test result can be stressful, especially when you are expecting. Based on what your say, you can have confidence in your doc and the negative result of your second test. The Western Blot test is a confirmatory test that is definitive, provided you were not infected during the three-months before your exam. For more info on the window period, see How long does an HIV test take? and HIV Transmission: When does it show up on a blood test? If the Western Blot is negative, you do not have any HIV antibodies in your blood. If this still concerns you, you can always have another HIV test. When your blood is tested for HIV, the lab first performs what is known as an EIA or ELISA (enzyme-linked

Q: 

defning charataristic of hiv

A: The virus can go undetected, with minor flu-like symptoms that are merely annoying for a long time as it sets up to overtake the immune system. Prominent symptoms of HIV are fever, weight loss, achey muscles and joint pain, headaches, skin rashes or persistent infections especially of the respiratory system. The most conclusive evidence of HIV is in blood tests which can be done in your doctor''s office or in an anonymous clinic. Your doctor will confirm the diagnosis of HIV infection through these blood tests. The initial screening test is called enzyme linked immunosorbent assay (ELISA). It detects disease-fighting proteins in your immune system (antibodies) specific to HIV. A Western blot...


Q: 

Herpes Testing and Results

A: Hi Shena, Although it seems like you increased your antibody level 2-3x (0.06 to 0.17), it is not thought to be "positive" reflecting antibody (your body"s reaction to a viral infection) to the virus until the numbers exceed (1.09) depending on the test technology. Other things can cause variations in these antibody tests. That is why low levels of antibody are not significant indicators of anything. Most of these tests are enzyme-linked immunosorbent assays (ELISA), whereby a chemical luminescence is measured by a light emitting and recording piece of equipment. An instrument measures and assigns an artibrary numerical value to the "strength" of the chemical reaction. If the number exceeds...


Q: 

Herpes Testing...

A: Hi Hannah, How did your guy friend find out he had herpes? There are 4 types of herpes testing. These descriptions are from the excellent resource, WebMD <http://www.webmd.com/genital-herpes/Herpes-Tests>: 1) Herpes viral culture. Cells or fluid from a fresh sore are collected with a cotton swab and placed in a culture container. A viral culture is regarded as the most specific method of diagnosing a genital herpes infection. 2) Herpes virus antigen detection test. Cells from a fresh sore are scraped off and then smeared onto a microscope slide. This test detects markers (called antigens) on the surface of cells infected with the herpes virus. This test may be done in addition to or in place of a viral culture. 3) Polymerase chain reaction (PCR) test. PCR testing can be...


Q: 

home access test

A: Hi Robert, I cannot say for certain, but I presume this is either a finger prick with a drop of blood, or a mouth swab. In order to do a Western Blot confirmatory test for HIV, you need to provide a tube of blood, which only a lab through a clinic or doctor"s office can order. The various rapid tests available don"t collect enough of a specimen to run those confirmatory tests. I"m not sure if the actual testing technolgy used is ELISA (enzyme linked immunosorbant assay) or something else. Is there a reason why you fear you may have been HIV infected? One of the good things about anonymous or confidential test sites that do such testing besides the fact that the test is free and essentially immediate, is that...


Q: 

Gonorrhea

A: Hello Lora, Gee, I know that such news is awful. First I would suggest that you speak with the doctor"s office to find out EXACTLY what tests were performed, and what the actual results were.   The Pap smear test may show nonspecific INFLAMMATORY changes, but in and by itself, cannot diagnose specific infections like gonorrhea or chlamydia. Paps are specifically designed to detect early cellular changes suggestive of precancerous changes caused by the human papilloma virus (HPV). Frequently, ACUTE inflammatory changes are indeed due to gonorrhea or chlamydia, but there are CHRONIC inflammatory processes that are due to a physiologic maturation of the cervix in women in their 20s, 30s, and 40s, known as "squamous metaplasia (SM)."  The Pap test examines superficially shed...
