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.

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.

When the heart is unable to pump blood around the body efficiently, it is known as heart failure. Heart failure can affect either the left or right side of the heart, or in some cases, both sides. The condition can be brought on by a number of diseases including high blood pressure, heart valve disease, blood clot in the coronary arteries and heart muscle disease.

Symptoms include shortness of breath, breathing problems, coughing, fatigue, leg swelling, eczema type rash and accumulation of fluid in the organs or abdominal cavity. Heart failure is usually diagnosed by a combination of medical history along with an examination that will check out such issues as heart sounds, heart rate, heart murmurs, fluid on the lungs, swollen legs, swollen neck veins or an enlarged liver. It can also be diagnosed by means of a chest x-ray, an ECG and blood samples. Doctors can also find out what caused the heart failure by performing additional blood tests so certain viral infections can be spotted, an ultrasound of the heart, a coronary artery examinations (done by injecting a dye into the left and right coronary arteries), exercise testing carried out on a treadmill and by taking a biopsy of a small bit of heart muscle.

Heart Failure

Ways to avoid heart failure include stopping smoking, a change of diet as well as avoiding overeating, exercising more often and getting problems such as high blood pressure or high cholesterol treated in a timely manner.
