Symptoms of HIV / AIDS:
Depending on the phase of the infection, the symptoms of HIV and AIDS vary. In early HIV infection, a person may have no signs or symptoms at all. Nonetheless, a person may develop a brief (two to four-week) flu-like illness when first infected with HIV. The signs and symptoms in this phase of infection include fever, sore throat, headache, rash and swollen lymph glands. It's also important to note that someone is still able to transmit the virus to others even when he/she doesn't have any symptoms.
In the later phase of infection, an infected person may remain symptom-free for close to nine years or more ("Symptoms" par, 3). As the virus continues to multiply and destroy the immune cells in this phase, the infected person may develop chronic symptoms or mild infections. These mild infections or chronic symptoms include diarrhea, weight loss, swollen lymph nodes, fever and cough and shortness of breath.
The last or latest phase of infection occurs within 10 or more years after the initial infection. During this phase, the appearance of more serious symptoms is evident and the infection may proceed to the official definition of AIDS. By this time, the immune system has been severely damaged and the signs and symptoms include chronic diarrhea, dry cough, soaking night sweats, weight loss, headaches, blurred and distorted vision and fever higher than 38 C.
AIDS-Defining Illnesses and Infections:
In addition to a laboratory-based AIDS diagnosis, the independent and presumptive diagnosis of AIDS is based on the presence of an AIDS-defining illness in a person whose HIV positivity and CD4 cell count are unknown. The variety of infections and diseases experienced by a patient with a weakened immune system is usually referred to as AIDS-defining illnesses ("AIDS-defining illnesses" par, 1).
The occurrence of an AIDS-defining illness is a sign that the infected person has entered the latest phase of HIV infection and is developing AIDS. These AIDS-defining illnesses are in four major categories namely opportunistic infections, central and peripheral nervous systems' diseases, malignancies and wasting syndrome. The examples of diseases affecting the central or peripheral nervous system include AIDS dementia complex, neuropathy, myelopathy and myopathy.
Natural AIDS Immunity:
Despite HIV / AIDS being a deadly disease, it has been discovered that about 2% of HIV patients were protected in some way. According to American and Chinese researchers, a group of bodily proteins block...
HIV Vaccine It Takes a Village Advances in medical treatment follow two paths more or less simultaneously. The first of these is the basic and directed scientific research that is needed to provide the concepts and solutions that may be channeled into particular treatments or cures. The second is equally important in terms of the ways in which medicine is conducted in the current age: The infrastructure to fund medical developments, to
HIV Nursing The human immunodeficiency virus (HIV) is a retrovirus (actually a lentivirus) that eventually causes the acquired immunodeficiency syndrome (AIDS; World Health Organization [WHO], 2014). There are two subtypes of the HIV virus: HIV -- 1 in HIV -- 2 (the agent in the epidemiological triangle). Both are transmitted to the host (humans) via the exchange of bodily fluids such as by sexual contact, rectal contact, blood, or breast milk
HIV Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system causing the individual to be at risk for opportunity infections, or infections that come about because the immune system is weak. It is a slow progressive disease that is present throughout the body. Humans can get infected with HIV through contact with tissues, such as vaginal, anal area, mouth, eyes, or a break in the skin, such
Healthy People 2020' initiative (HP2020) greatly emphasizes social health determinants, health inequity factors, and income and educational goals. Further, it adopts a broader perspective of the health effects of natural and manmade environments. The National Prevention and Health Promotion Council, by building on this initiative, offers a new means to implement a government-wide 'health in every policy' approach. Several NPS (National Prevention Strategy) interventions will extend across sectors and departments,
Focus and Purpose of the paperHIV has become a very contentious and controversial illness for many around the world. HIV has become a societal health concern as it continues to grow as a result of increased sexual activity of individuals around the world. In the United States alone roughly 1.5 million people have HIV. Even more alarming is that roughly 20% of these individuals do not know they have the
Customer Inserts His/Her Name Explain how HIV infects CD4+ cells? The HIV (human immunodeficiency virus) is the virus which belongs to a group of viruses known as the retroviruses. HIV causes in AIDS (acquired immunodeficiency syndrome) by infecting the cells of the human and uses up all the energy inside the cells which is required for the growth and development of human cells. AIDS is a fatal disease in which the immunity
