Knowledge is Power

When Darwin propounded his theories ‘struggle for existence’ and ‘survival of the fittest’ in the mid 19th century, he had scientifically proved that homosapiens were the most superior of all animals. It was not only due to some special physical attributes of human beings, but primarily due to their immense capacity to adjust. The power of speech, memory, etc. all helped the human beings reach great heights from where they command and control all other animals, and controlling the forces of nature to a large extent.

Importance of Knowledge in Today’s World
The culture, society, thought, science and technology are the men’s powerful weapons. The societies which are scientifically more advanced have a better place in hierarchy. In today’s world, the power of physical strength has been given least importance as compared to the power of knowledge.

This is not only true for the societies and groups, but also for the individuals. The ones with more knowledge and sharp minds do better in life as now we have meritocracy, i.e. merit-based society. Nowadays, the standard of measurement of knowledge is tested through examination, discussions, interviews and performances.

The knowledge today provides opportunities to hold positions, which by the sanction of the society, carry some rights. These rights are actually the powers which go along with that position. The more organized and complex the society and civilization become, the more will be the importance of knowledge. This is because complexity and organization cannot be managed by people who lack knowledge. Thus, we can say that in the present world, knowledge is power.

Information on AIDS – Symptoms, Causes and Treatment

AIDS stands for Acquired Immune Deficiency Syndrome. AIDS gradually reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections by making the body vulnerable to life-threatening illnesses. People with AIDS also have an increased risk of developing various cancers.

What are the causes of AIDS?
AIDS is caused by a retrovirus called HIV, the Human Immunodeficiency Virus. This virus causes slow but constant damage to the immune system cells, thereby leading the body to have difficulty in fighting off the infections. HIV is usually transmitted through sharing needles, unprotected sex, and from mother to infant before or during delivery or while breastfeeding.

Symptoms of AIDS – HIV Infection
People who become infected with HIV may not notice any immediate change in their health. However, some suffer from a flu-like illness within a few weeks of becoming infected, have complaints of fever, headache, tiredness, and may also develop a rash or swollen glands. These symptoms usually disappear within a few weeks after which the person feels normal. This asymptomatic phase often lasts for years. The median time to receive an AIDS diagnosis among those infected with HIV is 7-10 years.

Treatment of AIDS
The treatment of AIDS includes the antiretroviral medications which control the reproduction of the virus slow down the progression of the disease. When used in combination, these medications are termed Highly Active Antiretroviral Therapy (HAART). HAART combines three or more anti-HIV medications in a daily regimen.

When you start to choose antiretroviral treatment, you must adhere to it. People with this condition should take the advice of the experts to know the latest mode of therapy.
