Public Health Challenges in HIV Control
Science & Technology
- PYQs8
- Articles1
Background
This concept is crucial for GS2 (Health, Governance, Social Justice) as it highlights critical gaps in public health policy implementation, the social determinants of health, and the need for adaptive strategies in managing major infectious diseases like HIV. It reflects on the effectiveness of welfare schemes and the challenges faced by vulnerable populations.
Public health challenges in disease control involve identifying affected populations, ensuring access to testing and treatment, overcoming social barriers like stigma, and adapting to evolving epidemiological landscapes. Effective programs require robust surveillance, community engagement, and policy support to achieve disease elimination or control.
Facts & tables
- Undiagnosed Cases
- Over 56,000 people in Karnataka are unaware of their HIV status, posing a major challenge to early diagnosis.
- Barriers to Testing
- Reluctance for voluntary HIV testing due to stigma and inadequate awareness, particularly among young people.
- Importance of Early Intervention
- Early diagnosis and linkage to antiretroviral therapy (ART) are crucial for individual health and preventing transmission.
- Institutional Framework
- National AIDS Control Organisation (NACO) and state societies like KSAPS lead control efforts.

Over 56,000 in Karnataka unaware of HIV status; dating apps pose new challenge to tracing infections
Challenges in HIV control include a high number of undiagnosed cases, social stigma hindering voluntary testing, and the need for effective contact tracing and awareness campaigns, despite widespread availability of free testing and treatment.

Which of the following diseases can be transmitted from one person to another through tattooing?
1. Chikungunya
2. Hepatitis B
3. HIV-AIDS
Select the correct answer using the codes given below.
* Chikungunya is a mosquito-borne viral disease that cannot be spread through tattooing. * Hepatitis B is a liver infection that can lead to liver failure and cancer. It's spread through contact with the blood, open sores, or body fluids of an infected person. * HIV is a virus that destroys the white blood cells responsible for fighting infections. It can result in AIDS, the final stage of infection. It spreads mainly through unprotected sex, sharing drug needles, or contact with infected blood.
'Wolbachia method' is sometimes talked about with reference to which one of the following?
The Wolbachia method is a biological method that utilises the Wolbachia bacteria to control the spread of mosquito-borne diseases, particularly dengue fever. * Wolbachia naturally infects some insect species, but not Aedes aegypti mosquitoes, the primary vector for dengue fever transmission. Scientists introduce Wolbachia into Aedes aegypti populations. Wolbachia reduces the ability of these mosquitoes to transmit dengue virus. * As Wolbachia spreads through the mosquito population, it can significantly reduce the incidence of dengue fever. * This method offers a natural and sustainable approach to controlling dengue fever, a major public health concern in tropical and subtropical regions.
What is the importance of using Pneumococcal Conjugate Vaccines in India?
1. These vaccines are effective against pneumonia as well as meningitis and sepsis.
2. Dependence on antibiotics that are not effective against drug-resistant bacteria can be reduced.
3. These vaccines have no side effects and cause no allergic reactions.
Select the correct answer using the code given below:
Statement 1 is correct. Pneumococcal Conjugate Vaccines (PCVs) are effective in preventing several serious diseases caused by Streptococcus pneumoniae bacteria. This includes pneumonia, meningitis (inflammation of the meninges surrounding the brain and spinal cord), and sepsis (a life-threatening blood infection). Statement 2 is also correct. The growing prevalence of antibiotic-resistant strains of Streptococcus pneumoniae is a major concern. PCV vaccination helps reduce dependence on antibiotics, particularly for these resistant strains. This lowers the risk of antibiotic overuse and emergence of further resistance. Statement 3 is incorrect. While most people experience no serious side effects with PCV vaccines, there can be mild reactions like redness, swelling, or soreness at the injection site. Serious allergic reactions are rare.
Which one of the following statements is not correct?
Option A is correct. Both Hepatitis B virus and HIV (Human Immunodeficiency Virus) can be transmitted through blood-to-blood contact, sexual contact, and from mother to child during childbirth. Option B is incorrect. Unlike Hepatitis C, there is a vaccine available for Hepatitis B. The Hepatitis B vaccine is highly effective in preventing Hepatitis B virus infection. Option C is correct. According to global health statistics, the number of people infected with Hepatitis B and C viruses combined is indeed several times more than those infected with HIV. Option D is correct. Many individuals infected with Hepatitis B and C viruses may not show any symptoms for years or even decades. This is known as chronic hepatitis, and it can lead to severe liver damage if left untreated.
Consider the following:
1. Bacteria
2. Fungi
3. Virus
Which of the above can be cultured in artificial/synthetic medium?
* Bacteria can be cultured and grown in various artificial culture media, such as nutrient broth, agar plates, or other specific media formulations. Bacteria can metabolize and utilize the nutrients provided in these synthetic culture media to grow and reproduce. * Fungi can also be cultured in artificial media, such as potato dextrose agar, Sabouraud dextrose agar, or other specialized fungal growth media. Fungi can utilize the organic compounds and nutrients present in these synthetic media to support their growth and development. * Viruses, on the other hand, are obligate intracellular parasites and cannot be directly cultured in artificial or synthetic media. Viruses require living host cells to replicate and propagate, as they lack the necessary machinery for autonomous growth and reproduction.

Consider the following statements:
1. Some microorganisms can grow in environments with temperature above the boiling point of water.
2. Some microorganisms can grow in environments with temperature below the freezing point of water.
3. Some microorganisms can grow in highly acidic environment with a pH below 3.
How many of the above statements are correct?
* Statement 1 is correct: Pyrolobus fumarii, an archaeon living at 113 °C in Atlantic hydrothermal vents.Pyrococcus furiosus, an archaeon which thrives at 100 °C, first discovered in Italy near a volcanic vent. * Statement 2 is correct: Psychrophiles or cryophiles (adj. psychrophilic or cryophilic) are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from 20 °C to 20 °C. * Statement 3 is correct: Acidophiles are microorganisms that show optimal growth in highly acidic environments. These are of two types. The extreme acidophiles dwell in environments with a pH value < 3, and moderate acidophiles grow optimally in conditions having pH values ranging between 3 and 5.
Consider the following diseases
1. Diphtheria
2. Chickenpox
3. Smallpox
Which of the above diseases has/have been eradicated in India?
Statement 1 is incorrect: The Government introduced the Pentavalent vaccine, which also fights against Diphtheria. This implies that Diphtheria is still prevalent. Statement 2 is incorrect: Chickenpox is still widespread among the population. Statement 3 is correct: Smallpox has been eradicated from India. India declared itself free of smallpox in 1979.
Which of the following are the reasons for the occurrence of multi-drug resistance in microbial pathogens in India?
1. Genetic predisposition of some people
2. Taking incorrect doses of antibiotics to cure diseases
3. Using antibiotics in livestock farming
4. Multiple chronic diseases in some people
Select the correct answer using the code given below:
Statement 1 is incorrect. While genetic factors can contribute to susceptibility to infections, they are not directly related to the occurrence of multi-drug resistance in microbial pathogens. Statement 2 is correct. Incorrect use of antibiotics, including taking incorrect doses or not completing the full course of treatment, can contribute to the development of drug resistance in microbial pathogens. Statement 3 is correct. The widespread use of antibiotics in livestock farming can lead to the development of drug-resistant pathogens that can affect both animals and humans. Statement 4 is incorrect. While individuals with chronic diseases may be more susceptible to infections, this factor is not directly related to the occurrence of multi-drug resistance in microbial pathogens.
