HIV Viral Infection
Most people infected with the virus show few, if any, symptoms for a few years .But during this asymptomatic period, is actively multiplying, infecting, and kill cells in the immune system, particularly CD4+ T cells. People are very infectious during this early phase. As the immune system weakens, symptoms begin to emerge. Some people ,have develop symptoms within a month or two of exposure to these people may have a flu-like illness. If you recognize symptoms of as soon as possible start the treatment quickly its will help you to improve the immune system's response to HIV. This precaution is useful for you to reduce the chance of transmitting the virus to others. This topic discusses the early signs and symptoms of .
HIV infection is usually acquired through sexual intercourse, exposure to contaminated blood or body fluids, or transmission from an affected woman to her baby during pregnancy, birth, or breast-feeding. In other words, infection is not spread by casual contact but rather through direct exposure to infected blood or body fluids. Human immunodeficiency virus (HIV) infection is infection with a virus that gradually destroys cells in the immune system. Symptoms of infection develop in 50 to 90 percent of infected patients. Some people who contract experience very strong symptoms, but others experience none at all.
HIV infection is highly contagious at this stage because there are large amounts of the virus in the blood and other bodily fluids. As an example, a man could potentially infect 7 to 24 percent of susceptible female partners during the first two months of infection. Recognizing symptoms early, being tested for HIV, and starting treatment as soon as possible could help to decrease the risk of transmitting to another person. The initial signs and symptoms of include problems like fever, muscle and joint pain, and swollen lymph nodes. Because these signs and symptoms may be caused by other common illnesses like the flu, most people do not initially realize that they have HIV.
In most patients, symptoms of begin about two to four weeks after exposure. However, there have been instances in which up to 10 months have passed between exposure and the first signs and symptoms of infection.
The symptoms typically have an abrupt onset, beginning with a fever between 100.4ºF (38ºC) to 104ºF (40ºC). Most patients tend to develop the "full-blown" syndrome within one to two days. During the second week of the illness, most patients also have painless swelling of certain lymph nodes, including those under the arms and in the neck. Although the lymph nodes decrease in size after the first few weeks, some moderate swelling remains. Some patients develop mild enlargement of the spleen (known as splenomegaly).
On average, these symptoms last for about two weeks. However, some patients experience lingering fatigue, listlessness, or depression that lasts for weeks to months.
Skin, mouth, genital symptoms ¡ª A characteristic feature of acute infection is open sores or ulcers involving the mucous membranes and skin in certain areas of the body. They may be located in the mouth; the esophagus (throat, which extends from the mouth to the stomach); the anus; or the penis. Ulceration involving the esophagus often causes pain during swallowing. The ulcers tend to be shallow, with sharply defined edges, and are typically swollen and painful.Many patients also develop a rash or reddish inflammation of the skin about two to three days after the onset of fever. The rash usually

affects the face, neck, and upper chest or may be more widespread, involving skin of the scalp, the arms and legs, and the palms and soles. The inflammation is usually pink to deep red spots and/or small, solid, slightly raised areas of the skin. Itching is rare and tends to be mild.
Digestive symptoms ¡ª Many patients with primary infection develop nausea and vomiting, diarrhea, lack of appetite (known as anorexia), and associated weight loss. Rarely, more severe abnormalities of the digestive system develop, such as inflammation of the liver or the pancreas.
Respiratory symptoms ¡ª A dry cough is usually the only respiratory symptom associated with acute infection. A few rare cases have been reported in which patients developed inflammation of the lungs, resulting in difficulty breathing, coughing, and insufficient supply of oxygen to tissues.
Neurological symptoms ¡ª Headaches are common in persons with primary infection. Patients often describe pain behind the eyes that worsens with eye movement. Rarely, more severe neuralgic features have been reported, including:
Inflammation of the protective membranes that cover the brain and spinal cord (meningitis), with associated fever, severe headache, skin rash, abnormal sensitivity to light, or other signs
Inflammation of the brain (encephalitis), sometimes with meningitis. Symptoms can vary and may include fever, headache, confusion, personality disturbances, and episodes of uncontrolled electrical activity in the brain (seizures).
Impairment of certain "peripheral nerves" or motor and sensory nerves outside the brain and spinal cord. For example, following acute infection, some patients develop facial nerve paralysis; paralysis and muscle wasting (shrinking of muscle) of the arm; or Guillain-Barr¨¦ syndrome.
Guillain-Barr¨¦ syndrome causes weakness, tingling, and numbness that begins in the legs and progresses upward to the chest, arms, and facial area. Weakness is rapidly progressive and can sometimes lead to paralysis.
Opportunistic infections ¡ª After becoming infected with HIV, the immune system may not function as well to protect the body from organisms that do not usually cause disease. These organisms cause infections known as "opportunistic infections". While these opportunistic infections are more common in patients with AIDS who have had for many years, they can occur less commonly in people with primary infection as well.
Opportunistic infections may include yeast infections in the mouth or esophagus. Yeast infections are caused by Candida, a yeast-like fungal organism that is normally found on the skin and in the mouth, intestinal tract, and vagina in healthy individuals. Candidacies of the mouth, also known as thrush, causes cream-colored, slightly raised patches in the mouth, soreness, and easy bleeding. Candidacies of the esophagus may cause difficulty swallowing. Candidacies of the vagina is known as a yeast infection . Candidacies does occur in people without HIV, although people with are at a higher risk for this and other types of opportunistic infection.
There is no way to know for sure if someone else has HIV. Many people with look perfectly healthy. Other people who are sick with may have symptoms that are identical to other common illnesses. You cannot tell by looking whether someone is positive. The only way to know for sure is if someone tells you. It is important to consider how well you know someone and how much you trust them when talking about sex and HIV.
