Swine flu is a disease that affects pigs and is a highly contagious type of respiratory disease caused by a version of the influenza A virus. Typically, swine flu is of the subtype designated as H1N1, and this is also the subtype that is currently affecting humans.

H1N1 Swine Flu Virus

Although swine flu normally affects pigs, it can sometimes jump to a different species, which is what has happened with humans. Symptoms of swine flu are, on the whole, very similar to normal seasonal influenza outbreaks in humans and can range between no symptoms at all or very mild symptoms, to severe and even fatal pneumonia. Because these symptoms are similar to the normal flu symptoms, swine flu is almost impossible to distinguish from normal flu, unless specifically looked for by a doctor.

Humans can catch swine flu either by contact with pigs that are infected, which is the most common way, and contact with humans that are infected, which is less common. For human to human infection to occur, very close contact needs to occur between the two parties.

Swine Flu Symptoms

The symptoms of swine flu in humans is very similar to normal influenza symptoms, as mentioned above, and these can be aches, chills, coughing, diarrhea, headache, sore throat, fever, fatigue and vomiting. Most previous cases of swine flu in humans has cleared up without any medical assistance, but there are a couple of drugs that are successful in treating the condition – adamantanes and inhibitors of influenza neuraminidase.

Rotavirus infection affects the stomach and intestines in children with symptoms including diarrhea and vomiting. Most cases of the rotavirus infection are mild and usually clear up without medical intervention within a few days but some children, especially toddlers under the age of two, can be at risk of dehydration so it is essential to keep them hydrated with plenty of fluids.

The rotavirus infection is spread by infected people who haven’t washed their hands properly after going to the toilet. This can cause tiny amounts of infected feces being passed on to the child.  Small amounts of these infected feces can also be carried in the air resulting in the child inhaling them. Most children will have contracted the rotavirus infection by the age of five.  The rotavirus infection is more common during the winter and spring and it is usually common for the first virus to be the worst as after that the child will have built up some immunity.  It is for this reason that the rotavirus is rare in adults.

Rotavirus Infection

The rotavirus is extremely contagious in children and can even infect children who have already had the infection due to full immunity not being built up.  It is a good idea to isolate an infected child for a period of at least 48 hours after they have stopped having diarrhea and vomiting.

Symptoms of the rotavirus infection include rapid onset of diarrhea and vomiting and also occasionally a high temperature of 38C or above however it is important to recognize the signs of dehydration as this can occur if not enough fluids are taken.  Signs of dehydration include weakness, rapid breathing, little or no urine, or dry mouth and eyes.

The most important thing to do for a child with the rotavirus infection is to keep them hydrated and the infection will usually pass within a few days.

The menopause is that period in a woman’s life when her periods stop permanently. It’s a natural process that marks the end of a females reproductive years and the average age at which this happens is 51, although it varies from woman to woman. The menopause actually takes place when there aren’t any more eggs in the ovaries. It is these eggs that stimulate the production of estrogen, but when the levels of this hormone drop in the blood, the menstrual cycle is disrupted.

Menopause

The menopause normally takes place gradually and for a few years prior to it a woman’s periods may become more irregular; occurring every couple of weeks or every few months. Bleeding may be a bit heavier during this time as well.

Some women do not suffer any symptoms on the onset of the menopause, but approximately eight out of ten women do. These symptoms can include hot flashes, night sweats, mood swings, palpitations, insomnia, dry skin, thinning hair, brittle nails, aches and pains, loss of libido, headaches, weight gain, and vaginal and urinary changes.

The lower levels of hormones brought on by the menopause can also increase the risks associated with other health issues in the long term, including osteoporosis, heart disease, stroke, weight gain and weakness of the pelvis and pelvic floor.

Physical exercise and changes in diet can help in the treatments of the menopause, as does hormone replacement therapy (HRT), which is designed to replace some of the hormones after the menopause occurs.
