Hepatitis & short definition

What Is hepatitis?

introduction 

Hepa means liver  ,titis mean inflammation:

 Hepatitis is an inflammation of the liver caused by a hepatitis virus:

An estimated 4.4 million Americans are living with chronic hepatitis; most do not know they are infected. Most do not know HOW they were infected. About 80,000 new infections occur each year.

There are several types of viral hepatitis infections. The most common types of viral hepatitis in the U. S. are hepatitis A, B, and C. In recent years, hepatitis D and E viruses also have been identified. Related health issues affecting the liver are cirrhosis and liver cancer.

How do you get hepatitis? 


Hepatitis A is transmitted through fecal contaminated food or water and anal/oral contact. Transmission of hepatitis B (HBV) and C (HCV) involves contact with infected blood and body fluids. HBV is transmitted by infected body fluid. HCV is a blood born virus and is transmitted blood to blood. In some cases it is impossible to trace the source of a hepatitis infection. 



Can someone visit me if they have hepatitis?

It is perfectly safe to visit someone with hepatitis. Hepatitis is not transmitted through casual contact. It is OK to shake hands with, hug, or kiss someone who is infected with viral hepatitis.

Can hepatitis be sexually transmitted?

Yes, hepatitis B is often sexually transmitted. HBV is found in blood, semen, and vaginal fluids. The virus is 100 times more infectious than the HIV virus. Sexual partners of an infected person should practice safe sex. Partners not infected should get vaccinated for hepatitis B. (Those who have recovered from HBV are immune.)

Hepatitis C is not easily transmitted through sexual contact; researchers are uncertain how often transmission occurs through sex.

Hepatitis A may be spread through anal/oral contact during sex.

Is treatment available for hepatitis patients?

• Hepatitis A: no treatment for hepatitis A (HAV), however 99% of the time HAV will clear up over a period of a few weeks to months. 
• Hepatitis B: treatment for chronic hepatitis B usually consists of Alpha interferon and lamivudine. These drugs are effective in up to 40% of patients. 
• Hepatitis C: treatment for HCV will be interferon, ribavirin, and teleprevir or boceprevir. Currently these are the recommended drugs. Interferon can be taken alone or in combination with Ribavirin. Combination therapy is currently the treatment of choice. 
• Chronic hepatitis D is usually treated with pegylated interferon, although other potential treatments are under study. 
• Hepatitis E usually resolves on its own over several weeks to months.

EBOLA VIRUS DISEASE

EBOLA VIRUS  HEALTH IS WEALTH :-

EBOLA VIRUS DISEASE:-

INTRODUCTION ;

SIGNE & SYMPTOMS

Ebola virus disease (EVD) is a severe disease that causes haemorrhagic fever in humans and animals. Diseases that cause haemorrhagic fevers, such as Ebola, are often fatal as they affect the body's vascular system (how blood moves through the body). This can lead to significant internal bleeding and organ failure.

The current outbreak of Ebola is in Central and West Africa. There have not been any cases of Ebola in Canada.

The Ebola virus can spread through:

contact with infected animals
contact with blood, body fluids or tissues of infected persons
contact with medical equipment, such as needles, contaminated with infected body fluids
Exposure can occur in health care settings when staff do not wear appropriate protective equipment, such as masks, gowns and gloves.

As long as precautions are taken, there is low risk of contracting EVD in a country where the disease is present.

Symptoms show up 2 to 21 days after infection and usually include:

High fever.
Headache.
Joint and muscle aches.
Sore throat.
Weakness.
Stomach pain.
Lack of appetite.
