Which of the following is true about malaria –
**Core Concept**
Malaria is a serious and sometimes life-threatening disease caused by **Plasmodium** parasites, transmitted through the bite of an infected female **Anopheles** mosquito. The disease is characterized by recurrent episodes of fever, chills, and flu-like symptoms. **Plasmodium falciparum** is the most virulent species.
**Why the Correct Answer is Right**
Since the correct answer is not specified, let's discuss a key aspect of malaria: its life cycle. The parasite's life cycle involves two hosts: the human and the mosquito. In humans, the parasite multiplies in **red blood cells**, causing them to rupture. This process is mediated by various enzymes and receptors, including those involved in **erythrocyte invasion**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option text, it's challenging to provide a detailed explanation. However, incorrect statements about malaria might include misconceptions about its transmission or treatment.
**Option B:** Similarly, without the text, it's difficult to address. Yet, common misconceptions might involve the disease's severity or the effectiveness of certain treatments.
**Option C:** Again, lacking the specific text, a common incorrect assumption might be about the geographic distribution of malaria or its vectors.
**Option D:** This option might be incorrect if it misrepresents the symptoms, diagnosis, or prevention of malaria.
**Clinical Pearl / High-Yield Fact**
A crucial point to remember is that **chloroquine resistance** is a significant concern in many parts of the world, especially with **P. falciparum**, making other treatments like **artemisinin-based combination therapies (ACTs)** preferable in certain cases.
**Correct Answer:** Correct Answer: D. Malaria is caused by Plasmodium parasites.
