Hepatitis B is a virus that affects the liver. It is more prevalent in Asia and Africa and can be either acute (more common), resolving itself relatively quickly with no long term liver damage, or chronic (in about 20% of cases) lasting six months or more, and sometimes even for life with symptoms coming and going randomly.

Hepatitis B is normally transmitted via contact with infected bodily fluids or blood and only a very small amount of blood is required to transmit the disease because it is that infectious. In the developed world the virus is normally spread via sharing of contaminated needles, unprotected sex and the sharing such things as razor blades. In less developed countries where blood products are not screened properly or medical equipment is not sterilized adequately, this can also lead to the spread of the virus.

Hepatitis B viruses have an incubation period of between six weeks and six months, but approximately one third of all cases show no symptoms of the disease at all. In another third of cases, symptoms appear flu-like in nature and can include aches, pains and weakness; fever; headaches; loss of appetite; jaundice; diarrhea; and, vomiting and nausea. In the last third of cases, the virus can cause severe illness that can last for a long time (many months in some cases).

Vaccines are available nowadays against hepatitis B, but treatment for those infected normally includes nothing more than rest and recuperation. Drug treatments may be required for chronic types of the disease, to prevent damage to the liver and other parts of the body.

In a nutshell, an allergy can be defined as an abnormal reaction from an individual’s immune system normally against a harmless substance. Individuals with no allergies would not have a reaction to these substances, or allergens, but the body’s of those who do release certain chemicals and it is these that cause the allergy symptoms.

An allergy can range from such things as itchy eyes to rashes to runny nose and is so widespread that they can affect 25% of the population at some stage of their lives. People have to be aware though, that these symptoms can be caused by factors other than an allergy as well, and could well be from a disease instead. More or less anything can be classed as an allergen for an individual but the most common come from pollen, dust mites, pets, insects, industrial chemicals, certain medicines and some foods like eggs and milk.

Common Allergic Reactions

The immune system of an allergic person reacts by producing special kinds of antibodies called IgE when it thinks it is being “damaged” by an allergen, and these antibodies attack the invader. This procedure then causes other blood cells to discharge other chemicals, which together with the antibodies cause the allergic reaction symptoms.

Food Allergies

Syphilis is most often a sexually transmitted disease, although it can be passed on through injecting drugs into a vein, from an infected pregnant woman to the unborn infant (congenital syphilis), or through blood transfusions.  It cannot be passed through casual person to person contact, i.e. touching, sharing toilet facilities or sharing things such as cutlery, etc.

Syphilis can be quite dangerous as it can lie in the body undetected and then resurface many years later affecting organs such as the eyes, brain, heart or nervous system.

Syphilis

Primary syphilis starts with painless sores on the skin which are very contagious.  These sores are known as chancres and can if another person comes into contact with these typically during sexual contact, then they will more than likely contract the syphilis infection.

Typically, between two to ten weeks later, more symptoms will appear and this is known as secondary syphilis.  These symptoms include tiredness, headaches, sore throat and skin rashes.  These symptoms will then disappear but the infection can lie dormant for many years and can then return causing organ damage and even organ failure.

Primary syphilis can be quite mild and therefore the patient may not know they even have the disease before passing it on.  It can be treated with antibiotics.

Abstaining from sex is the only definite way to avoid catching the syphilis infection.  However condoms do offer protection.  Sex toys should never be shared.
