In nearly all countries of the world, back pain is the single largest cause of absence due to sickness from work. It is a chronic problem in a lot of people and a large proportion suffer from recurring problems. More often than not, the pain is due to minor damage that may have occurred to the muscles of ligaments of the back due to a variety of reasons such as lifting, twisting, being overweight or even standing in the wrong sort of position.

On other occasions it can be caused by more serious medical conditions such as a slipped disc, a disease like arthritis, muscle tears or scoliosis (curvature of the spine). When first suffering from back pain it is always advisable to visit a physician just to clarify the pain is not due to a treatable medical condition, and this is especially true in younger people.

Common Back Pain

Symptoms of back pain include a sharp pain in a specific area, a generalized ache in the region of the buttocks or lower back, stiffness and difficulty bending over. When the pain is due to a prolapsed disc there could be pressure on a nerve which will send pain radiating down the back of a leg to the foot. This is known as sciatica.

Back pain can occur to anyone of any age, but is more common in individuals who are overweight and those who sit in a slouching position for long periods of time. Treatment for back pain depends on the cause, but things like pain killers, losing weight and changing posture are the norm for “non-medical” back pain.

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.

West Nile Virus

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.
