Hiv or the human immunodeficiency virus is the lentivirus which causes hiv infection and leads to acquired immunodeficiency syndrome or aids.

The symptoms of hiv vary from person to person. There are three main stages of hiv infections, where each stage has different symptoms.

Here are some facts about the three stages of hiv infections along with the accompanying symptoms.

Acute hiv infection stage
This is the first stage of hiv infection and after three to four weeks of becoming hiv infected, people experience symptoms, which are similar to flu. This flu usually does not last more than two weeks.

Symptoms include:
Fever
Rashes on the body
A sore throat
Swelling of different glands
Headache
Joint and muscle pain
Improper digestion

These symptoms appear and indicate that the body is reacting to the hiv. Infected cells circulate throughout the blood, and the immune system produces hiv antibodies in order to attack the viruses. This process is termed as seroconversion, and it takes place within 45 days of getting infected. The levels of virus in your blood are quite high during this stage.

Clinical latency stage
This is the second stage of hiv infection, which follows the early stage. This stage is also known as chronic hiv stage. During this stage, hiv is active, but is reproduced at a very low level. People in this stage may not receive symptoms related to hiv or may get mild indications.

In case of people who do not take medicines for hiv treatment, this stage lasts for a long period. Some people, however, progress faster through this stage. Medicines should be taken to keep the virus in check. During this stage, people can transmit hiv to others very easily in spite of not experiencing any symptoms. People who are on medication stay suppressed virally and have a low level of hiv in their blood, and the risk of transmission is less.

Symptomic hiv infection or aids stage
This is the third stage of hiv infection, which is characterized by severe damage to the immune system of an hiv-virus affected person. A patient is likely to have serious infections and gets bacterial or fungal diseases. The infections are termed as opportunistic infections. The patient is now said to be having aids.

The symptoms of this stage are:
Loss of weight
Diarrhoea
Sweating at night
Fevers and persistent coughing
Problems in the mouth and skin
Infections on a regular basis
Illness and development of other diseases.

Hiv infection affects the body via three stages and leads to aids in the third stage. Each stage is accompanied by several symptoms.

Stages and Symptoms of HIV Infections

HIV: QUICK FACTSIntroductionThe human immunodeficiency virus (HIV) is a subgroup of retrovirus (lentivirus) that causes HIV infection. After a period of time, this infection leads to what is called acquired immunodeficiency syndrome (AIDS).

Epidemiology

According to the Centers for Disease Control and Prevention (CDC), from 2010-2015, the estimated rate of HIV infection in all 50 US states decreased from 14.2 per 100,000 population in 2010 to 12.3 per 100,000 population in 2015. In 2015, 39,513 individuals were diagnosed with HIV infection. From 2010 to 2014, the annual number of new HIV infections decreased by 9%.

Virology HIV-1 and HIV-2 are retroviruses in the Retroviridae family, Lentivirus genus. They are enveloped, diploid, single-stranded RNA viruses with a DNA intermediate.Upon entry into the target cell, the viral RNA genome is converted into double-stranded DNA by an enzyme, reverse transcriptase that is transported along with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integrase. HIV contains three retroviral genes, namely gag, pol, and env.

Gag gene: Encodes group-specific antigen; the inner structural proteins
Pol gene: Encodes polymerase; it also contains integrase and protease
Env gene: Encodes the viral envelope, the outer structural proteins responsible for cell-type specificity. Glycoprotein 120, the viral envelope protein, binds to the host CD4+molecule
Pathophysiology

HIV infects vital cells in the human immune system, such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells and leads to cellular immune deficiency. This results in the development of opportunistic infections and neoplastic processes.

Mode of Transmission
Sexual intercourse: Unprotected sexual intercourse; especially receptive anal intercourse and different sexual partnersContact with or transfer of blood, pre-ejaculate, semen, and vaginal fluids infected with the virus.Spread from an infected mother to her infant through breast milk. An HIV-positive mother can transmit HIV to her baby both during pregnancy and childbirth due to exposure to her blood or vaginal fluid.

Signs and Symptoms There are 3 categories of infection 

Category A: Asymptomatic HIV infection without a history of symptoms or AIDS-defining conditions
Category B: HIV infection with symptoms that are directly attributable to HIV infection
Category C: HIV infection with AIDS-defining opportunistic infections
Investigation

A high-sensitivity enzyme-linked immunosorbent assay (ELISA) should be used for screening.

Management

Start with antiretroviral therapy (ART) in all HIV-infected adults ready to start therapy. 
CD4 count is no longer a criterion for starting the therapy.
Use of nucleoside reverse transcriptase inhibitors and protease inhibitors.
For refractory cases, during the failing treatment regimen and before switching therapy, use rapid confirmation, perform resistance testing and reevaluate.

HIV - Quick Facts Need To Know!

Hearing that a person is HIV positive instantly makes us wary of him or her and unconsciously we may begin avoiding social interactions with them. However, HIV does not spread through the air or by water and hence there is no reason to ostracize HIV positive people. To understand how to prevent the transmission of HIV it is essential to first understand how the virus is transferred from one person to another. There are three ways in which this virus can be transmitted from an HIV positive person to another. These are:

Through blood
Through bodily fluids such as semen and vaginal or rectal fluids
From a mother to a child
Keeping this in mind, here are a few ways to prevent the transferring of HIV from one person to another:



Use only Disposable Syringes: Getting pricked by a needle that has been used on a HIV positive patient can increase your risk of suffering from the disease. Hence, insist on using a fresh needle for blood tests etc. Also ensure that the syringe and needle and destroyed after being used.
Registered Blood Banks: In case you need a blood transfusion, get blood only from registered blood banks. These blood banks need to run HIV screening tests before collecting blood and hence are guaranteed to have only HIV negative blood as opposed to local quacks.
Use a Condom: The only way to prevent the transference of HIV cells while having intercourse is by using a condom. This is essential not only for vaginal intercourse but for anal intercourse as well.
Get Tested: Today, an HIV screening test can be easily done and your results are guaranteed to be kept confidential. STDs can increase your risk of getting infected with HIV or spreading it to others. Get tested regularly for STDs and insist that your partners are checked for it as well. This is crucial if you have more than one sexual partner.
Limit the Number of Sexual Partners: The more number of people you have sex with, the higher your chance of getting infected with the virus and transmitting it to others. Remember, HIV has no overt symptoms that are visible to the naked eye.
HIV cannot be cured but it can be controlled through medication. Hence, if you suffer from this disease, follow the doctor's prescription religiously to prevent transmitting the virus to your partner. If you wish to discuss about any specific problem, you can consult a doctor.

HIV/AIDS - How To Prevent It?

Tuberculosis is an opportunistic infection caused by the bacteria Mycobacterium tuberculosis. The infections occurring in people with weak immunity as compared to the people with a healthy immune system are called as opportunistic infections. As, HIV enters the human body, it replicates and weakens the immune system which in turn increases the risk of contracting Tuberculosis in people already suffering from HIV infection.

An HIV and Tuberculosis co-infection occurs when an individual has both, the HIV infection and an either latent or active TB disease simultaneously.  Each disease acts in speeding up the progress of the other, when HIV and TB infection is present together in the body. HIV infection speeds up the progression from latent to active Tuberculosis, Mycobacterium tuberculosis also accelerates the progression of replication and spread of the HIV infection.

HIV infection and Tuberculosis are totally different type of infectious diseases. HIV is a viral infection and TB is a bacterial one. An HIV infected person will not contract TB unless a contact happens with a TB infected person. TB spreads via droplet infection and is communicable. If a person lives in a country with a high prevalence rate of TB, an HIV patient is highly susceptible to contracting the infection. In the similar manner, a person suffering from TB gets infected with the HIV infection only through the blood and bodily fluids borne route, with unprotected sexual intercourse with an HIV infected individual being the most important cause.

Amongst all the other opportunistic infections, TB occurs at an earlier stage in the course of an HIV infection than most other opportunistic infections. Mortality rate in the co-infected patients is more than twice that of HIV infected individuals without a TB infection. Even if a patient is undergoing anti-retroviral therapy, the death rates remain high in co-infected individuals.The natural history and course of TB gets altered in people with an infected immune system. The damage to immunity due to HIV infection causes a drastic reduction in the pathogen killing capacity of the body. In such patients if there is no anti-retroviral treatment prescribed, then the latency period between the infection and progression of disease gets eliminated. 

An active phase of TB is observed in such individuals progressing within a short span of time, ranging from weeks to months, rather than years as it normally should be spanning. Risk of progression from a latent stage to an active stage of TB is around 10-15 times greater in an HIV infected individual as compared to the non-infected person. Such individuals also communicate the disease more rapidly to others.Pulmonary tuberculosis in an HIV infected person can present similar symptoms like that of a classic TB disease. However, a co-infection can sometimes show less presenting TB symptoms, where even the chest X-ray scans can be observed to be normal. A  subclinical  phase of Tb in co-infected patients can cause delay in the diagnosis of the symptoms and subsequently affect the prognosis due to lack of timely treatment.

Social stigma and discrimination has caused an obstacle in provision of adequate treatment for people with HIV. Proper counseling  and initiatives taken to provide indiscriminate care can aid in identification of co-infection and earlier stages. Anti-retroviral treatment teamed up with anti-tubercular drug regimen is prescribed and a successful treatment for drug sensitive cases of TB can be provided with medications for 6-8 months.

How HIV & TB  Are Related?

Acquired Immune Deficiency Syndrome(AIDS) is caused by a virus called Human Immunodeficiency virus (HIV). It should be remembered that it is not necessary that a person having HIV is suffering from AIDS or will inevitably result in it. The illness damages the immune system of the person and makes them more vulnerable to diseases and infections. As the syndrome progresses, opportunistic infections attack the patient, ultimately causing their death.

What are the causes of AIDS?
The virus is spread by person-to-person contact like:
1. Through sexual contact.
2. By sharing the same needle or through blood transfusion.
3. The disease can be spread from mother to the newborn child.

What are the symptoms of AIDS?
1. You may have a high fever or suffer from constant diarrhea which may last for weeks.
2. Red rashes may appear on your skin.
3. You may feel weak and tired all the time.
4. You may have excessive sweating, particularly at night.
5. Your muscles and joints may ache.
6. Your swollen glands don t heal for weeks.

What are the complications related to AIDS?
During the last stage of infection, there is a high risk of having life-threatening diseases.These include:
1. Infections to the nervous system like meningitis, peripheral neuropathy.
2. Inflammation in the lower end of the esophagus.
3. Cancers like cervical cancer, neck cancer, and lymphomas.
4. Tuberculosis.

Can AIDS be treated with homeopathy?
Homeopathic treatment can be of a great help for such patients. It can boost up not only physical health but mental health too. It can combat opportunistic infections very effectively by boosting up the immunity of the patient. There are marvellous results with homeopathic medicines tried in Africa (an epidemic zone for AIDS). Many patients of AIDS are still waiting to die after using homeopathy and their quality of life has improved drastically. Homeopathy works by modulating the immunity which is an important factor in AIDS patient. Some of the homeopathy medicine used to treat symptoms of AIDS are:
1. Syphilinum
2. Arsenic iodum
3. Sulphur
4. Silica,
5. Tuberculinum
6. Kali carbonicum
7. Calcaria iodum
8. Bacillinum
9. Arsenica Album
10. Phosphorus
These medications can be used in conjuction with ART or antiretroviral therapy along with other treatments and has been shown to be very effective in alleviating some of the commonly encountered symptoms of AIDS related complications. But utmost care must ensured and these medicines should not be taken without consulting a homeopathic doctor.

HIV / AIDS - Can Homeopathy Medicines Helps in Treating it

HIV infection and AIDS (commonly referred to as HIV/AIDS) are caused by the Human Immunodeficiency Virus (HIV). HIV is transmitted sexually and through exchange of body fluids, such as blood. The HIV attacks our defense system (immune system) giving opportunity to many illnesses to attack the body. These infections (called opportunistic infections) range from common cold and diarrhea to life-threatening illnesses including uncommon pneumonias and cancers. The type, range and intensity of opportunistic infections vary with the severity of the HIV infection and the extent to which our immunity is compromised. 

AIDS is the last stage disorder of the HIV infection. Though there is no complete cure for the HIV-infection till date - despite thousands of scientists across the world working on it, spending countless hours of research involving billions of dollars - there has been tremendous progress in medicare improving the quality of life of the HIV-infected, in extending their life-span to almost normal levels and in preventing mother-child transmission. 

The key factors in extending the life-span, and in keeping good immunity and good health are 

balanced and nutritious diet

regular physical exercise

correct, consistent and lifelong use of the prescribed medicines

periodic medical checkups

staying psychologically positive and strong

good family support and

good lifestyle habits.

The last one involves maintaining good personal hygiene, avoiding smoking (active as well as passive), alcohol, recreational drugs, unhygienic and disease-prone environments and sedentary life style. Those who follow these will guidelines certainly have better prognoses. 

Diet:

A nutritious diet is of utmost importance to the HIV-infected, as adequate nutrition contributes to the development of the immune system, prevents malnutrition and wasting, achieves and maintains optimal body weight and strength, enhances the body s ability to fight opportunistic infections, helps delay the progression of HIV, improves the effectiveness of drug treatments, and improves the quality of life. 

Ensure that the food contains adequate macronutrients, that is, carbohydrates, proteins and fat, otherwise the patient may end up with - protein-energy malnutrition, manifesting itself in the weight loss and wasting that is typical of AIDS patients.

As per WHO, an HIV-infected person has additional nutrient requirements: 10-15 percent additional energy intake and 50 to 100 percent increase in protein intake as compared to a non HIV-infected person.

Consuming micronutrients (especially Vitamins A, B6 and B12, iron and zinc) is important for building a strong immune system and fighting infections.

Try and maintain a daily diet containing rice/roti, vegetables, legumes, and fruits which provide you energy and micronutrients. Choose foods that are low in saturated fat, trans fat, and cholesterol.

Eat at least two servings of fish each week. Oily fish, which contain omega-3 fatty acids, are best. If you cannot eat fish, you can also get omega-3 fats from omega-3 eggs, walnuts, flax seeds.

Better avoid fast foods.
