Introduction

Historical Context of HIV

How HIV Spreads

The main cause of HIV spread is body fluids that contain the virus. For the prevention of disease understanding its spread is necessary. Below are some reasons for HIV transmission:

Unprotected Sexual Contact:

Sexual intercourse with an infected person is the most common mode of HIV transmission. Vaginal, anal or oral sex causes the transmission of the virus in the bloodstream of an uninfected person.

Blood-to-Blood Contact:

HIV is transmitted through direct contact with infected blood. This occurs through sharing needles or syringes for drug use, or through accidental needlestick injuries in healthcare settings.

Mother-to-Child Transmission:

HIV virus is transmitted to a child after birth from an infected mother. Even breastfeeding also causes such transmission. The risk of such transmission is reduced by applying proper medical procedures.

Sharing of HIV-Contaminated Needles:

Sharing needles and other drug paraphernalia for injecting drugs with an infected person can lead to the transmission of HIV. This is a significant risk factor among individuals who use intravenous drugs.

Occupational Exposure:

Healthcare workers and staff are also at great risk during infected person treatment. Accidental exposure to infected blood, needlestick injuries, or mucous membrane contacts also infect a healthy person.

Important note: Casual cantacts such as hugging, kissing, hand shake do not spread the virus. The HIV virus has also no ability to transmitt through air, water, or insect bite.

HIV Symptoms and Stages

HIV viral infection progresses through several stages. Patients may experience different symptoms at different stages.

Important Note: Symptoms of HIV vary widely among individuals. Even some people unable experience symptoms for many years.

Below are some stages and symptoms of HIV infection:

Acute HIV Infection (Primary or Early Stage):

• Infected persons experience this stage within 2 to 4 weeks after initial exposure to the virus.
• Symptoms are like flu or other common infections like fever, fatigue, muscle ache, sore throat, swollen lymph nodes, rash, headache, and nausea.
• Not everyone with HIV experiences symptoms during this stage.

Clinical Latency (Chronic or Asymptomatic Stage):

• This stage possibly last for several years, and individuals may not experience significant symptoms.
• The HIV reproduces at a low level and the immune system can control the infection.
• Swollen lymph nodes can be experienced by some people but overall there may be no symptoms.

Symptomatic HIV Infection (Advanced or AIDS-Related Complex):

• As the immune system becomes more compromised, symptoms may appear.
• Symptoms include persistent fever, fatigue, weight loss, diarrhea, and night sweats.
• Infections or cancers may occur by taking advantage of the weak immune system.
• This stage is sometimes referred to as AIDS-Related Complex (ARC) and is a precursor to AIDS.

AIDS (Acquired Immunodeficiency Syndrome):

• The final stage of HIV infection is AIDS
• AIDS can severely damage the immune system which further leads to harmful infections or cancers.
• Pneumocystis pneumonia (PCP), Kaposi’s sarcoma, tuberculosis, and cryptococcal meningitis are common AIDS-related illnesses.
• Infected persons may survive for about three years if not treated properly.

Important Note: Progression from HIV to AIDS can be slowed or halted if proper medical care and therapy is accounted for. Effective management of infection depends on early detection and regular testing.

Prevention Strategies

Preventing HIV involves a combination of behavioral, medical, and educational strategies. Here are key prevention strategies:

Safe Sex Practices:

The risk of HIV transmission can be reduced by using condoms during sexual intercourse. Both male and female condoms play an important role in reducing viral infection.

Pre-Exposure Prophylaxis (PrEP):

Taking antiretroviral medications before potential exposure to HIV is called PrEP or Pre-Exposure Prophylaxis. It is preventive action taken to safeguard individuals who are at high risk of contracting the virus. These include people having HIV-positive partner or having high-risk behavior engagement.

Needle and Syringe Programs:

People who inject drugs should use sterile needles and syringes to prevent HIV transmission through the sharing of contaminated injecting equipment. Needle exchange programs and supervised injection facilities can help reduce the risk.

Testing and Counseling:

Proper and regular testing is essential for early detection of HIV and timely medical intervention. Diagnosis enables noninfected people to take appropriate steps to protect themselves and their loved ones.

HIV counseling provides information on risk reduction, safer sex practices, and coping with an HIV-positive diagnosis.

ART Treatment as Prevention (TasP):

HIV management and load reduction in infected persons can be done with the help of ART (Antiretroviral Therapy). Undetectable load volume reduces the risk of transmission among people.

Post-Exposure Prophylaxis (PEP):

PEP involves taking antiretroviral medications after potential exposure to HIV (such as unprotected sex or needlestick injuries). It is a time-limited intervention and must be initiated within 72 hours of exposure.

Promoting Safer Injection Practices:

Proper education on safe injection practices plays a vital role for drug-injected patients and other people in preventing the spread of HIV.

Preventing Mother-to-Child Transmission:

Taking antiretroviral medication during pregnancy can help pregnant women to reduce the risk of viral transmission to their infants. Avoid breastfeeding after birth.

Educational Campaigns and Awareness:

Public health campaigns aimed at raising awareness about HIV transmission, prevention, and destigmatizing the virus are essential. Education helps dispel myths and encourages responsible behavior.

Promoting Sexual Health:

Open communication plays a vital role in the proper sex education of people. Proper medical checkups and addressing sexual issues can contribute to overall HIV prevention efforts.

Challenges in HIV Awareness

There are several challenges in HIV awareness that persist globally. These challenges can vary across different regions, populations, and socio-economic contexts. Here are some common challenges:

Stigma and Discrimination:

HIV-infected people often face discrimination and prejudice. Which creat a sense of fear and shame from getting tested or seeking treatment.

Some people hide their HIV status due to the fear of judgment and rejection. They also hesitate to open discussions about prevention and treatment.

Lack of Access to Information:

Inadequate or incorrect information about HIV transmission, prevention, and treatment can contribute to the spread of misinformation and hinder effective awareness campaigns.

Underdeveloped countries also lack in resources to properly implement comprehensive HIV awareness programmes.

Inadequate Healthcare Infrastructure:

Access to HIV testing and counseling services may be limited in certain areas, preventing timely diagnosis and treatment initiation.

Insufficiently trained healthcare professionals can hinder the delivery of quality care and support for individuals living with HIV.

Economic Barriers:

The cost of antiretroviral therapy (ART) and other medications may be a barrier for some individuals, particularly in low-income communities.

Without proper health insurance, individuals may struggle to afford regular check-ups and necessary medications.

Cultural and Societal Factors:

Cultural norms and traditions can impact HIV awareness and prevention efforts, sometimes hindering the adoption of safer practices.

Gender-based discrimination and power imbalances can contribute to the vulnerability of certain groups, making it challenging to address HIV prevention effectively.

Youth Engagement:

Comprehensive sex education and HIV prevention programs tailored to the needs of young people may be insufficient or unavailable in some educational systems.

Migration and Mobility:

Populations on the move, such as refugees and migrants, may face challenges in accessing consistent healthcare and information about HIV prevention.

Emerging Challenges:

The intersection of HIV with other health issues, such as tuberculosis or non-communicable diseases, poses additional challenges for prevention and treatment.

HIV Misconceptions

HIV is the same as AIDS:

Casual contacts:

HIV from mosquito bites:

HIV is transmitted through mosquito bites. The virus is not present in sufficient quantities in the blood to infect another person through mosquito bites.

Restricted risk:

HIV-positive individuals always look sick:

Assessment by appearance:

There are no physical characteristics that can reliably indicate whether someone is HIV-positive. The only way to know for sure is through HIV testing.

Herbal remedies or alternative therapies:

HIV transmission through saliva, tears, or sweat:

HIV isn’t always transmitted through informal touch or the sharing of saliva, tears, or sweat. The virus is present in certain body fluids, along with blood, semen, vaginal fluids, and breast milk, but no longer in enough portions in different bodily fluids.
