Hepatitis A is an infection of the liver caused by the hepatitis A virus. The well-respected World Health Organization (WHO) estimates that almost 1.5 million new cases of hepatitis A related illnesses occur each year worldwide, with a much higher number of people than this affected without showing any symptoms. The condition is more prevalent in the developing world where poverty and sanitation issues are rampant.

Hepatitis A is regarded as an acute infection as opposed to a chronic one, but in rare occurrences it can cause liver damage that is life threatening. The severity of symptoms in patients with the virus varies from individual to individual and whereas some may have no symptoms at all, others may develop symptoms to those similar of catching flu. As a rule, the older a person is, the more severe the infection, and therefore the symptoms, will be.

Some of the symptoms associated with hepatitis A include tiredness, weakness, fever, headache, nausea, loss of appetite, vomiting, dehydration and diarrhea. After a week or so of these symptoms, jaundice will appear. This occurs because in hepatitis infections, the liver is unable to remove a substance known as bilirubin from the blood. The skin and whites of the eyes become a yellow color because of the buildup of this pigment.

Hepatitis can be avoided be taking the following precautions: high levels of personal hygiene, drinking safe tap water and getting vaccinated against the disease if a visit to a high risk country is to be taken.

West Nile Virus is a disease which is spread by mosquitoes and for the most part is not a serious disease.  Often there are no symptoms but sometimes if an infected mosquito bites somebody it can lead to inflammation of the brain, spinal cord or the tissues which surround the brain and spinal cord.

The West Nile Virus is caused when a mosquito feeds on an infected bird and then bites an animal or human.  Most of the time people with West Nile Virus have no symptoms but some people experience symptoms which include headache, muscle ache, loss of appetite, fever, nausea, vomiting, back pain, abdominal pain, sore throat and diarrhea.  The symptoms will usually surface roughly three to 14 days after the infected mosquito bite and will last for approximately three to six days.

There can be complications however, and sometimes the virus can cause an infection of the brain and nervous system.  Symptoms of this would include severe headaches, high fever, stiff neck, lack of co-ordination, muscle tremors, convulsions, coma, disorientation, coma or even partial paralysis.

West Nile Virus is not serious if symptoms are mild.  However, if the virus spreads to the brain or spinal cord it can lead to brain damage or death.

The best way to avoid the virus is to protect against mosquito bites at all times when away.  It is advisable to check whether the virus is present in the country you are visiting and take extra precautions against being bitten.

Vaginitis is the name given to an infection of the vagina.  Symptoms of vaginitis include a sore itching vagina with possible abnormal discharge.  There are various types of vaginitis and each type has its own cause and symptoms.  These different types are yeast infections, bacterial vaginosis, non-infectious vaginitis, and trichomoniasis.

Yeast or Candida infections are the most common type of vaginitis and are caused by an excess of the fungus Candida growing in the vagina.  Symptoms of yeast infections include a thick white discharge which causes the vagina to become itchy and red.

Vaginitis

Bacterial vaginosis is a frequent infection which affects women of reproductive age and is caused by bacteria in the vagina.  Symptoms of bacterial vaginosis can include a thin smelly vaginal discharge although some women find they have no symptoms at all and only become aware of the infection during a visit to the gynecologist.

Non-infectious vaginitis can be caused by a reaction to products used such as soaps, fabric softeners, douches, vaginal sprays or spermicidal products.  It can cause the vagina to become itchy or burn and is accompanied by a vaginal discharge.

Trichomoniasis is an infection of the vagina which is caused by a single cell parasite.  This form of vaginitis is a sexually transmitted disease and will cause soreness, itching, and burning of the vagina.  It can also cause a burning feeling when urinating.

Each type of vaginitis has its own treatment.  An anti-yeast infection is used to treat yeast infection.  An antibiotic is used to treat bacterial vaginosis as there is no remedy which can be purchased over the counter.  In order to treat non-infectious vaginitis it is necessary to cease using the product which caused the reaction and a cream can be used to relieve symptoms. Trichomoniasis is treated with an antibiotic but it is important to avoid any sexual contact until it has been treated.
