Sexually transmitted diseases - class-XII

HIV is Human Immunodeficiency Virus that causes AIDS. Hepatitis-B is a viral disease and it has not been eradicated yet. Gonorrhoea is a bacterial disease. Trichomoniasis is a protozoan disease.

A. Sexually transmitted diseases are called venereal diseases. B. Genital herpes is caused by a virus and is considered incurable. C. Sterilization in males is vasectomy and in females is tubectomy.

Syphilis is a bacterial disease caused by Treponema pallidum. It is transmitted through sexual contact and from mother to foetus during pregnancy. In the first stage of this disease, painless ulcer or chancre appears on the genitals and swelling of lymph nodes occur.

Hepatitis D, also known as delta hepatitis, is a liver infection caused by the hepatitis D virus (HDV). Hepatitis D only occurs in people who are infected with the Hepatitis B virus, since HDV requires the help of HBV to replicate. Therefore, by getting a vaccination of Hepatitis B we can save ourselves from Hepatitis D. 

Chlamydia is the most common type of bacterial STD. It doesn't cause any symptoms, hence is difficult to detect in the early stages. 

Diseases or infections which are transmitted through sexual intercourse are collectively called sexually transmitted diseases or venereal diseases or reproductive tract infections. Gonorrhoea, syphilis, genital herpes, Chlamydiasis, Trichomoniasis, Hepatitis-B, AIDS are some of the STDs. Loiasis is a eye infection causedby loa loa worm. Thus option D is the correct answer.

The sexually transmitted diseases also called venereal diseases, are spread by sexual intercourse with an infected person. The major venereal diseases are syphilis and gonorrhea. Fluid discharge, slight pain, swelling in genital region are the early symptom of sexually transmitted disease.

Chlamydia is a common sexually transmitted infection, that can be passed on through sex without a condom with someone chlamydia (even if they don't have symptoms), or from a pregnant woman to her unborn baby. It can be prevented by using male or female condoms during sex. A simple urine test will show whether you have chlamydia. Chlamydia is easily treatable with antibiotics.

Haemophilus ducreyi is a fastidious gram-negative coccobacillus bacteria, which causes the sexually transmitted disease chancroid, a major cause of genital ulceration in developing countries, characterized by painful sores on the genitalia. 

PCR test is used to detect HIV's genetic material, called RNA, in the patient's specimens. ELISA test for the antibodies & antigens in the blood of the affected person. 

Trichomoniasis is a commonly occurring sexually transmitted disease caused by a parasite. It causes different symptoms in the affected men & women.

AIDS, which is caused by the HIV virus, attacks the immune system, making it weak, hence the individual suffers from many different types of diseases. Also in the early stages of the disease, very little or no symptoms, like a headache, fever, fatigue and sore throat appear, which is misunderstood for some kinds of flu.  

The most common type of STD's are chlamydia, herpes & gonorrhea. The early symptoms in each one of these are swelling near the genitals & fluid discharge from the reproductive organs. 

Tricomoniasis is one of the most common type of sexually transmitted disease , caused by a parasite . While HIV , HPV & Herpes can be spread by causes other than unprotected sex with infected person .

The most common type of STD in the world is AIDS , which is spread by HIV virus . It can be detected by ELISA test . It detects and measures the antibodies in the blood .  So, the correct option is  'ELISA'.

The most common sexually transmitted diseases are HIV/AIDS, Chlamydia, Gonorrhea, Syphilis,Hepatitis Mycoplasma genitalium, Trichomoniasis, HPV, crabs/pubic mice.

A. Candidiasis- Candida albicans (Fungi)

Sexually transmitted infections are more common in 15-24 years age
group. Gonorrhoea, syphilis, genital
herpes, chlamydiasis, genital warts,
trichomoniasis, hepatitis-B and AIDS are
some of the common STDs. Haemophilia is
sex-linked recessive disease, which show
its transmission from unaffected carrier
female to some of male progeny. Sickle cell
anaemia is an autoimmune linked recessive
trait in which both the partners are carrier
for the gene

Diseases or infections which are transmitted through sexual intercourse with infected persons are collectively called sexually transmitted diseases(STDs).

All of the diseases like AIDS, Gonorrhoea, hepatitis- B, chlamydiosis, and syphilis are sexually transmitted diseases. While cholera, malaria, hemophilia are water-borne, parasitic and Mendelian disorders respectively.

Hepatitis B or HBV can cause yellowing of skin & eyes, jaundice, dark urine, abdominal pain & in severe cases, liver failure. 

Chlamydiosis or Chlamydia infection is the most commonly sexually transmitted disease and affects the human genital organs. This is caused by the bacterium Chlamydia trachomatis. Gonorrhea or gonococcal urethritis, is a sexually transmitted infection found in men and is caused by the bacterium Neisseria gonorrhoeae and this infection do not show much difference from that caused by Chlamydia trachomatis in men.
