HIV Transmission Routes and Latency Period — NEET Biology
📚 Practice ConceptDo you know—when do people need repeated blood transfusion? Find out and make a list of such conditions. It is important to note that HIV/AIDS is not spread by mere touch or physical contact; it spreads only through body fluids. It is, hence, imperative, for the physical and psychological well-being, that the HIV/AIDS infected persons are not isolated from family and society. There is always a time-lag between the infection and appearance of AIDS symptoms. This period may vary from a few months to many years (usually 5-10 years).
Which of the following statements regarding the transmission and control of HIV/AIDS are NOT correct? S1: Mass awareness campaigns are crucial as HIV infection often spreads due to conscious behavior patterns and ignorance. S2: Ensuring the use of only disposable needles and syringes is a key step to prevent HIV transmission, especially among intravenous drug abusers. S3: HIV infection can be prevented by avoiding insect vectors such as mosquitoes, as they can transmit the virus during blood feeding. S4: Regular screening of blood and blood products before transfusion is essential to make blood safe from HIV. S5: Promoting safe sexual practices, including the free distribution of condoms, helps control the spread of HIV. S6: People with HIV infection should be isolated from family and society to prevent its wider spread.
View solution & NCERT explanation
Correct answer: D — S3 and S6
The question focuses on understanding the correct and incorrect methods of HIV transmission and control based on NCERT guidelines. S1: Mass awareness campaigns are indeed crucial because HIV infection often spreads due to conscious behavior patterns and ignorance, as stated in the NCERT text. So, S1 is correct. S2: Ensuring the use of only disposable needles and syringes is a specific measure mentioned in NCERT to prevent HIV transmission, particularly among drug abusers. So, S2 is correct. S3: HIV/AIDS is not spread by mere touch or physical contact; it spreads only through body fluids. Mosquitoes are not vectors for HIV transmission. So, S3 is NOT correct. S4: Regular screening of blood and blood products from blood banks for HIV is explicitly mentioned as a step to make blood safe for transfusion. So, S4 is correct. S5: Advocating safe sex and free distribution of condoms are vital steps in preventing the spread of HIV. So, S5 is correct. S6: HIV/AIDS-infected persons should not be isolated from family and society; rather, they need help and sympathy. Isolation would increase the chances of wider spread. So, S6 is NOT correct. Therefore, statements S3 and S6 are NOT correct. The correct option is A because it correctly identifies the statements that are not correct.
