First of all we should try and explain what influenza (flu) is. There are three main types: A, B and C, with B and C only infecting humans and influenza A being able to infect humans, animals and birds. The surface of each influenza A virus contains two types of protein, neuraminidase (N), of which there are nine types, and haemagglutinin (H), of which there are sixteen types. Consequently, there are lots of sub-strains of the influenza A virus and they are given names depending on the type of proteins found on the surface. Examples of these sub-strains could be H1N1, H1N2 and H2N3.

Another characteristic of the A strain is that it has the ability to produce new strains – in other words, mutate. It is as these new strains occur that new types of flu are discovered.

Bird flu is a strain of influenza A that affects birds, of which all species can be affected. Whereas wild birds can carry the disease when they migrate, they don’t usually become ill with it whereas poultry birds like turkeys and chickens do become ill. The virus spreads easily between these birds.

Bird Flu

It is the H5N1 virus that is causing all the problems with humans at the moment. This strain has affected birds for almost half a century, but it mutated back in 1997 in the Far East and spread to humans. As of yet this strain of the virus cannot be transferred from human to human, only from bird to bird or sometime bird to human.

Multiple sclerosis (MS) is an autoimmune condition that affects the nerves located in the brain and spinal cord, giving rise to issues with muscle control, balance and vision. It can also affect memory as well as associated mood swings and emotions.

MS sufferers can find that their symptoms are different from other sufferers, while also varying from day to day. Sufferers often find that the symptoms can get worse with exercise or heat. In general though, the most common symptoms of MS are problems with the eyes (blurring and double vision); muscle weakness or stiffness; fatigue; loss of coordination; bowel and bladder issues; tingling or numbness of the skin; general pain; anxiety and depression; difficulty swallowing and talking; and sexual problems. Although these may appear to be many symptoms, a sufferer is highly unlikely to develop all of them and certainly not at the same time.

There are four kinds of MS: benign MS, relapsing-remitting MS, secondary progressive MS and primary progressive MS. The exact reasons that an individual contracts the condition are not fully understood at this present moment in time, although several different factors are thought to be implicated. Although it is not a hereditary condition, having specific genes may make a person more susceptible to it. There could also be some environmental factors involved – bacteria or viruses may trigger the immune system to attack its own body. Also, the place of residence may be an issue. It is known, for example, that MS is more common in countries further from the equatorial regions.

Although there are treatments available for the symptoms of MS, there isn’t actually a cure at present.

Multiple Sclerosis

Scabies is an infection caused by a tiny mite that burrows under the skin usually on the hands, ankles, wrists or male genitalia.  They then live there and lay eggs.  Having these mites under the skin induces an allergic reaction which in turn causes a rash with extreme itching.  Scabies is more common in children but can occur at any age.  It is highly contagious and is spread through direct person to person contact.  The scabies mite cannot live long outside the body but sometimes it can be spread from contact with clothes, linen, etc if the infected person has just touched them.

Scabies

The rash usually develops between two to six weeks after the person has become infected.  The itching usually worsens at night or after a bath or shower when skin is hot. Sometimes burrow marks can be seen on the skin but most often they are hidden by marks caused by scratching or the rash itself.  These burrow marks are thin zigzag lines and are easier to see on hands or feet.

Scabies is treated with a scabicide which is a lotion or cream but it needs to be applied correctly or it may not work.  It needs to be applied twice with a week between each application and should be applied to cool dry skin.  The cream then should be washed off between eight and twenty four hours later.

Everyone in close contact with a person who has been diagnosed with scabies needs to be treated at the same time to make sure the infection has been completely erased.  All bed linen should be washed at a high temperature to make sure that all mites are killed.
