Infectious Diseases Practice Questions

Q: Identify the symbol in the image:

MDT. ***Correct Answer: MDT (Multi-Drug Therapy)*** - The image depicts a human figure divided into two halves, one red and one orange, against a yellow circle. This specific logo is widely recognized as representing the **Multi-Drug Therapy (MDT)** for leprosy under the National Leprosy Eradication Programme. - The use of two colors symbolizes the different drugs used in combination therapy, and the human figure within a circle represents holistic treatment and the goal of restoring health and dignity to individuals affected by leprosy. - MDT is the cornerstone of leprosy treatment and consists of a combination of rifampicin, dapsone, and clofazimine. *Incorrect: DOTS* - **DOTS (Directly Observed Treatment, Short-course)** is a strategy for tuberculosis control, not leprosy. - The DOTS logo typically focuses on lungs or abstract representations of TB treatment and does not match the image shown. *Incorrect: ART* - **ART (Antiretroviral Therapy)** is used for HIV/AIDS treatment. - ART program logos generally incorporate themes related to HIV/AIDS awareness, often including ribbons or stylized health symbols, which differ from the image provided. *Incorrect: NRHM* - **NRHM (National Rural Health Mission)** is a government initiative in India for strengthening rural healthcare infrastructure. - The NRHM logo typically incorporates national symbols or themes related to rural health and community, such as families or health workers, not the dual-colored human figure shown in the image.

Q: Which is not true about the organization shown?

Launched in 1987. ***Launched in 1987*** - The **National AIDS Control Organisation (NACO)** was actually established in **1992** as a division of the Ministry of Health and Family Welfare, Government of India. - Its formation was a response to the growing HIV/AIDS epidemic in India, five years *after* the first case was reported in the country in 1986. *Group I states = with > 1% HIV infection in high risk groups* - This statement is **true** and accurately describes one of the classifications for states based on HIV prevalence among high-risk groups as defined by NACO. - NACO categorizes states to tailor intervention strategies, with Group I states requiring intense focused interventions due to higher prevalence rates. *RTI/STI clinics are known as "Suraksha clinics"* - This statement is **true**. NACO has indeed branded clinics providing services for **Reproductive Tract Infections (RTIs)** and **Sexually Transmitted Infections (STIs)** as "Suraksha clinics" (meaning 'protection' clinics). - These clinics are crucial for preventing the spread of HIV by treating co-morbid STIs, which can increase HIV transmission. *Red ribbon clubs are formed in colleges* - This statement is **true**. **Red Ribbon Clubs (RRCs)** are a prominent initiative by NACO, primarily established in colleges and universities. - Their main objective is to spread awareness about HIV/AIDS, promote voluntary blood donation, and instill positive health-seeking behavior among youth.

Q: The following symbol denotes:

RSBY. ***RSBY*** - The image depicts a logo representing several stylized human figures (resembling **antibodies** or active people) around a central circle, which is the **logo for Rashtriya Swasthya Bima Yojana (RSBY)**, a government-funded health insurance scheme for the poor in India. - This symbol is widely recognized in India as representing the **health insurance coverage** provided under the RSBY scheme. *Factory act* - The Factories Act of 1948 in India is a legislation aimed at **regulating working conditions in factories**, with a focus on safety, health, and welfare of workers. - Its symbols or representations usually involve industrial safety, machinery, or worker protection, and not the stylized human figures shown. *NREGA* - NREGA (**National Rural Employment Guarantee Act**), later known as MGNREGA, is an Indian labor law and social security measure that guarantees the 'right to work' and aims to enhance livelihood security in rural areas. - Its official logos typically involve imagery related to agriculture, rural development, or hands working together, not the specific design shown. *RTI act* - The Right to Information (RTI) Act is an Indian law that mandates timely response to citizen requests for government information. - Its symbols are usually associated with transparency, information access, or scales of justice, which are not reflected in the given image.

Q: The following symbol denotes:

Kishori Shakti Abhiyan. ***Kishori Shakti Abhiyan*** - The symbol is the **official logo of Kishori Shakti Abhiyan (KSA)**, an Indian government scheme focusing on the holistic development of adolescent girls. - The stylized image of a girl looking upwards with a bindi and hair signifies **female empowerment, growth, and aspiration**, central themes of the KSA program. *Sarv Shiksha Abhiyan* - The **Sarva Shiksha Abhiyan (SSA)** logo typically features a child reading a book, often with a symbolic representation of education and literacy. - This logo focuses on **education for all**, which is distinct from the specific focus on adolescent girls in the provided image. *Save the girl child campaign* - While related to female welfare, "Save the girl child campaign" is a **generic term**, and this specific logo is not universally associated with it. - Various campaigns under this umbrella have different logos, often depicting themes of **birth and survival of girls.** *Beti bachao beti padhao andolan* - The **Beti Bachao Beti Padhao (BBBP)** campaign has a distinct logo, usually incorporating elements like a mother and child or educational symbols. - Its objective is to **address declining child sex ratio** and promote girl education, which differs from the *Kishori Shakti Abhiyan's* focus on adolescent girls' overall development.

Q: The following symbol is used to depict awareness for which disease?

Breast cancer. ***Breast cancer*** - The **pink ribbon** is an internationally recognised symbol for breast cancer awareness. - It is prominently used in campaigns, especially during **Breast Cancer Awareness Month** in October, to promote screening and early detection. *Diabetes* - The symbol for diabetes awareness is typically a **blue circle**, representing the global unity in the fight against diabetes. - While it's a significant health issue, it does not use the pink ribbon for its awareness campaigns. *Cervical cancer* - The awareness ribbon for cervical cancer is typically **teal and white**. - This symbol highlights the importance of vaccination and regular screening tests like Pap smears. *Hypertension* - There isn't a universally recognized ribbon symbol for hypertension; however, sometimes a **red dress** or variations of a **red ribbon** are used for heart health awareness in general. - Hypertension awareness focuses on lifestyle modifications, regular monitoring, and medication adherence.

Q: The kit shown in the picture is used for treatment of:

Leprosy. ***Leprosy*** - The pictured blister pack is a characteristic "MDT blister pack" or **Multi-Drug Therapy (MDT) kit**, specifically designed for the treatment of **leprosy**. - These packs contain the combination of **dapsone, rifampicin, and clofazimine**, pre-sorted for daily or monthly administration to simplify treatment and improve adherence. *Tuberculosis* - While tuberculosis also uses multi-drug therapy, the **kit's specific layout and combination of drugs** are not typical for standard TB treatment regimens. - TB drug regimens usually involve drugs like isoniazid, rifampin, pyrazinamide, and ethambutol, often packaged differently. *Malaria* - Treatment for malaria involves **antimalarial drugs** (e.g., chloroquine, artemisinin-based combination therapies), which are packaged and administered in a manner distinct from the pictured leprosy MDT kit. - The drug types and administration schedule would differ significantly. *HIV* - HIV treatment (Antiretroviral Therapy or ART) involves a combination of **antiretroviral drugs**, which are typically packaged in daily dose combinations but **do not resemble the specific leprosy MDT kit** in appearance or the types of medications included. - ART regimens are highly varied and personalized based on viral load and resistance profiles.

Q: The life cycle shown below is of:

Nipah virus. ***Nipah virus*** - The diagram clearly illustrates the transmission pathways characteristic of Nipah virus, involving **fruit bats (flying foxes)** as primary reservoirs, **pigs as intermediate hosts**, and human infection through direct contact with infected animals or consumption of **contaminated date palm sap**. - The described "rapid pig-to-pig transmission" and "people consume contaminated date palm sap" are key epidemiological features of Nipah virus outbreaks in Southeast Asia. *Japanese encephalitis* - Japanese encephalitis is primarily transmitted by **mosquitoes** (Culex species) and involves **water birds** as primary reservoirs, and pigs as amplifying hosts. - The life cycle shown does not depict mosquito vectors or water birds, which are central to Japanese encephalitis transmission. *Chandipura virus* - Chandipura virus is an arbovirus transmitted by **sandflies** and often associated with seasonal outbreaks of acute encephalitis, primarily affecting children. - Its transmission cycle does not involve bats, pigs, or contaminated date palm sap as depicted in the image. *Influenza* - Influenza viruses circulate mainly among **humans, birds, and pigs**, with transmission primarily through **respiratory droplets** or direct contact. - While pigs can play a role in certain influenza strains (e.g., swine flu), the involvement of bats and consumption of contaminated sap is not characteristic of human influenza transmission.

Q: Which is correct sequence of handwashing technique?

A → B → C. ***A → B → C*** - Follows the **WHO 6-step handwashing protocol** progression from **palm-to-palm with fingers interlaced** (step 3) to **backs of fingers against opposing palm** (step 4) to **rotational thumb rubbing** (step 5). - This sequence ensures **systematic cleaning** of all hand surfaces, moving from basic interdigital spaces to more complex finger positions before focusing on the thumb. *A → C → B* - Skips the **backs of fingers cleaning** (step 4) before proceeding to **thumb cleaning**, disrupting the systematic progression. - **Thumb cleaning** should come after thorough **interdigital cleaning** to ensure complete coverage of all finger surfaces. *B → A → C* - Begins with **backs of fingers to opposing palm**, which requires **fingers interlocked**, before completing basic **palm-to-palm interlacing**. - This reverses the **WHO protocol** by attempting advanced finger positioning before establishing proper **interdigital contact**. *C → B → A* - Starts with **thumb cleaning** before addressing **interdigital spaces**, completely reversing the systematic approach. - **Thumb cleaning** should be performed after **thorough finger and palm cleaning** to prevent recontamination of cleaned areas.

Q: The following leprosy kit is used for management of:

PB adult treatment. ***PB adult treatment*** - The blister pack contains only **two drugs**: **Rifampicin (red capsules)** and **Dapsone (white tablets)**, which is characteristic of the **PB (paucibacillary) regimen** for adults. - The **absence of Clofazimine** (light brown tablets) confirms this is a **PB treatment kit**, as MB regimens always include Clofazimine as the third drug. *PB child treatment* - While PB child treatment also uses **Rifampicin and Dapsone**, the dosages would be **lower** (Rifampicin 450mg monthly, Dapsone 50mg daily) compared to adult doses. - The tablet quantities and packaging size in the image suggest **adult dosing** rather than pediatric formulations. *MB child treatment* - **MB (multibacillary) regimens** require **three drugs**: Rifampicin, Dapsone, and **Clofazimine**, which is clearly **absent** from this blister pack. - Child MB treatment would use **reduced doses** of all three medications based on body weight. *MB adult treatment* - **MB adult treatment** includes **Clofazimine (300mg monthly + 50mg daily)** as the third essential drug, which is **not present** in this kit. - MB regimens are used for **12 months** duration, while this PB kit is designed for **6 months** treatment duration.

Q: Which one of the following terms is an "all-or-none phenomenon" and is best described as termination of all transmission of infection by extermination of the infectious agent?

Disease eradication. ***Disease eradication*** - **Eradication** means the permanent reduction to zero of the worldwide incidence of infection caused by a specific agent as a result of deliberate efforts, with no risk of reintroduction. - It is an "**all-or-none phenomenon**" because the infectious agent is completely exterminated globally, signifying a definitive end to transmission. *Disease surveillance* - **Disease surveillance** is the ongoing systematic collection, analysis, interpretation, and dissemination of health data essential to the planning, implementation, and evaluation of public health practice. - It does not involve the termination or extermination of an infectious agent but rather monitors its spread and impact. *Disease elimination* - **Elimination** refers to the reduction to zero of the incidence of a specified disease in a defined geographical area as a result of deliberate efforts. - While local transmission is stopped, the infectious agent may still exist elsewhere, meaning there is still a risk of reintroduction. *Disease control* - **Disease control** involves ongoing public health efforts to reduce the incidence, prevalence, morbidity, and mortality of an infectious disease to a locally acceptable level. - It focuses on managing and reducing the burden of disease, not necessarily eradicating the causative agent.
