Consider the following statements about Malaria1. Malaria is caused by...
Malaria is a mosquito-borne infectious disease caused by parasites of the genus Plasmodium. It is a major global health problem, particularly in tropical and subtropical regions. Let's analyze the given statements:
1. Malaria is caused by the virus.
This statement is incorrect. Malaria is not caused by a virus, but by a group of parasites known as Plasmodium. There are five species of Plasmodium that can infect humans, namely Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale, and Plasmodium knowlesi.
2. Malaria is transmitted through the bites of female Anopheles mosquitoes.
This statement is correct. Malaria is primarily transmitted through the bites of infected female Anopheles mosquitoes. When a mosquito bites a person who is infected with malaria, it ingests the parasites along with the person's blood. The parasites then develop and multiply within the mosquito's body. When the infected mosquito bites another person, it injects the parasites into their bloodstream, leading to the transmission of malaria.
3. There is no vaccine available for the cure of malaria.
This statement is correct. Currently, there is no licensed vaccine available for the complete cure of malaria. However, there are ongoing research and development efforts to develop an effective vaccine. The most advanced vaccine candidate is RTS,S, which targets the Plasmodium falciparum parasite. While the RTS,S vaccine has shown some efficacy in clinical trials, it is not yet widely available.
In conclusion, statement 2 is correct as malaria is indeed transmitted through the bites of female Anopheles mosquitoes. Statements 1 and 3 are incorrect as malaria is not caused by a virus, but by Plasmodium parasites, and there is no currently available vaccine for the complete cure of malaria. Therefore, the correct answer is option B (2 only).

Consider the following statements about Malaria1. Malaria is caused by...
Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable. Vaccines against malaria: RTS,S/AS01 (RTS,S) is the first and, to date, the only vaccine to show partial protection against malaria in young children. It acts against P. falciparum, the most deadly malaria parasite globally and the most prevalent in Africa.
The number of malaria cases reported till September 16 this year is higher than those recorded last year, as per data released by the Delhi municipal corporations. The data reveal that 247 cases of malaria were reported this year till the second week of September. Nearly 100 cases were reported in the past two weeks. During the same period in 2018, there were 225 cases; 410 in 2017; 286 in 2016; 66 in 2015; and 120 in 2014.
