The common cold can be described as an infection of the higher reaches of the respiratory tract, or in other words the throat, the nasal passages and the nose. It is interesting to note that there are over two hundred different virus’ that can presently cause the common cold, but the main culprit in adults is the rhinoviruses, of which there are a hundred different strains and are classified as nose virus’.

When an individual becomes affected by a cold, the symptoms usually show up around two days later and these include a sore throat, a runny nose and sneezing. Later symptoms can consist of watery eyes, headache, muscle aches, stuffed nose, and a general feeling of being unwell. The symptoms of a cold can last anywhere from two to seven days but in some cases may even last up to two weeks.

Common Cold

People who have a common cold may find that is accompanied by bronchitis, laryngitis, an ear infection or with those who suffer from asthma, a worsening of the condition. Common cold infections are so prevalent that it is estimated that an adult will suffer between two and five colds each year. Because of this, the condition is the leading cause of people missing work days through illness.

Contrary to belief, colds are actually not very contagious when compared to other infections. Prolonged and close contact is required for the virus to spread and it must get into the nose for there to be infection.

Diarrhea can simply be defined as loose, watery stools. People are classed as having diarrhea if they pass such stools more than three times a day. If somebody has acute diarrhea, the problem usually persists for a couple of days only and then clears up of its own accord. On the other hand, if an individual suffers from prolonged diarrhea, meaning more than a couple of days, it could be symptomatic of a more serious problem, as well as posing a risk of dehydration. Dehydration is especially dangerous in young children and the elderly and as such should be treated immediately to help avoid any future potential health issues.

Diarrhea

Individuals of any age can get diarrhea and you may be surprised to find out that the average in developed countries will have a bout of acute diarrhea approximately four times per year. Acute diarrhea is normally associated with a parasitic, a viral or a bacterial infection whereas a chronic diarrhea is typically related to some sort of functional disorder like irritable bowel disorder.

Some other causes of the condition include food intolerances, a reaction to certain medicines, and intestinal diseases such as Crohn’s and celiac disease. Diarrhea can be accompanied by abdominal pains, cramps, nausea, bloating and an urgent overwhelming need to use the toilet.

More often than not, the only treatment required for diarrhea is the replacement of lost fluids. There are some medicines available that can stop the condition, but these aren’t recommended for individuals who have diarrhea caused by a parasitic or bacterial infection. This is because if you stop the diarrhea before the bacteria or parasite is removed from the intestines they will be trapped there prolonging the problem.

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.
