A disease characterized by inflammation of liver is known as hepatitis. There are five main types of hepatitis that are caused by a virus:
This is caused by eating infected food or water. The food or water is infected with a virus called HAV (hepatitis A virus). Anal-oral contact during sex can also be a cause. Nearly everyone who develops Hepatitis A makes a full recovery - it does not lead to chronic disease.
It is a disease cause by type B hepatitis virus (HBV). It is one of the common diseases of liver and it is 100 times more infectious than HIV and AIDS. This disease develops gradually without symptoms. So, it is known as 'Silent Killer'. Its incubation period is 6 weeks to 6 months. The patient dies of cirrhosis and cancer of the liver.
Signs and symptoms of hepatitis B, ranging from mild to severe. Signs and symptoms of hepatitis B may include:
It is caused by type C hepatitis virus (HCV).
Mode of transmission
It is transmitted to the embryo during pregnancy.
We have split this list of prevention tips into the individual variation types of hepatitis.
The sexually transmitted diseases are a group of communicable diseases that are transmitted through unsafe sexual contact. Virus, bacteria, pretoria, fungus ans ectoparasites cause them. The common STDs are syphilis, gonorrhoea, HIV/AIDS, etc.
Syphilis is a chronic sexually transmitted disease caused by 'spirochete' or Treponema Pallidum'. It mainly affects heart, liver and brain. The average incubation period of syphilis is approximately three weeks.
A single pain less lesion or sore called a chancre appears in the genitals, anus, lips, tongue, mouth, breast, fingers, etc and they disappear after 1-5 weeks of appearance.
After one week to six months of primary stage, the ulcer secondary syphilis signs appear which are as follows: -
In the final stage, the disease is considered communicable for approximately four years following initial infection. Syphilis, at the least stage, can become destructive in nature
Gonorrhoea is an infection of genitourinary tract caused by Neisseria Gonococcus. It mainly affects the mucus membrane of genitourinary tract. Its incubation period is approximately 3-9 days.
Modes of transmission
AIDS stands for Acquired Immuno Deficiency Syndrome. It is caused by a retrovirus known as HIV (Human Immuno-deficiency Virus). AIDS is not a disease but a stage in which various symptoms and syndromes can emerge.
Modes of transmission
Signs and symptoms
a. Major Signs
b. Minor signs
When a person causes Hepatitis B, the liver of the body is affected.
The bacteria known as Treponema Pallidum causes syphilis.
HIV stands for Human Immuno Deficiency Virus and AIDS for Acquired Immune Deficiency Syndrome.
Gonorrhea is a contagious disease that is brought by a germ known as Neisseria Gonococcus and affects genitals, urinary track, rectum, cervix etc. The germ is received due to sexual contact with infected person or other sources like vaginal discharges containing the germ.
AIDS is transmitted through following ways:
To prevent from sexually transmitted infections, following measures should be adopted. (1) Sexual contact in early age should not be done because of lack of appropriate and necessary skills before right age. (2) Sex with many persons should be avoided as STIs occur due to the sexual contact with STIs infected persons. (3) Condom should be used properly while having sexual contact which prevents STIs as well as unwanted pregnancy. (4) Blood should be checked properly before transfusion of it because HIV & AIDS and other STIs are transmitted through the blood. (5) Syringe and piercing tools should be well sterilized before reuse or used once only. (6) Widespread awareness on the safer sexual behaviours.
