u003cstrongu003eIs malaria contagious?u003c/strongu003e

No, malaria transmission cannot take place in the same way as a cold or the flu, because the malaria parasite is not found in an infected person’s saliva. Nor can it be sexually transmitted. The only way that malaria can spread from one person to another is through blood, as with blood transfusions, organ transplants, needle sharing, or if it is acquired by an unborn child from its mother. Otherwise, malaria is normally transmitted by being bitten by a female Anopheles mosquito, infected through a previous blood meal taken from an infected person.

u003cstrongu003eIs there a malaria vaccine?u003c/strongu003e

The world’s first malaria vaccine, known as RTS, S, is being piloted in Ghana, Kenya, and Malawi, starting in 2018. However, it is not otherwise available yet. Despite many decades of research and development efforts, there is currently no commercially available malaria vaccine. The complexity of the malaria parasite, Plasmodium, makes the development of a malaria vaccine very difficult.

u003cstrongu003eCan a person acquire immunity to malaria through exposure?u003c/strongu003e

After repeated attacks of malaria, a person may develop semi-immunity. Such a person can often still be infected by malaria parasites, but may not develop severe disease. After time spent away from a malaria-endemic area, this acquired immunity will gradually disappear. Many cases of malaria in travelers are acquired by people who have moved to an area without malaria, visited the malaria-affected areas where they grew up, and not taken antimalarial tablets because they assumed they were still immune.

u003cstrongu003eIs malaria caused by a virus or bacteria?u003c/strongu003e

Malaria is not caused by a virus or bacteria. Malaria is caused by a parasite known as Plasmodium, which is normally spread through infected mosquitoes. A mosquito takes a blood meal from an infected human, taking in Plasmodia which are in the blood. About a week later, the mosquito takes another blood meal and injects the Plasmodia into the body of another person, spreading the malaria disease.

**What is Malaria?**

**Malaria** is a life-threatening parasitic disease that is ⁣transmitted by ⁤mosquitoes infected with the malaria parasite. ⁢It ‍primarily affects people⁢ in tropical and subtropical⁤ regions of the world,⁣ particularly⁢ in Africa,‍ Asia, and Latin America.

**Transmission:**

Malaria is transmitted through the bite of an infected female Anopheles mosquito. When the mosquito bites a⁤ person, the ⁢parasite enters the bloodstream through the mosquito’s saliva.

**Symptoms:**

Symptoms‌ may appear ‌within 10 days to 4 weeks after the bite. Initial symptoms include:

* Fever, chills, and sweating

* Muscle pain

* Fatigue

* Headache

If‍ left ⁣untreated, ⁤malaria ‍can lead ‌to severe complications,‍ including:

* ‍Anemia

* Cerebral malaria (infection of the brain)

* Kidney failure

* Liver‍ failure

**Diagnosis:**

Diagnosis of malaria requires a ‌blood test to detect ⁣the parasite. ⁤Diagnosis‌ should be ‍prompt to prevent severe complications.

**Treatment:**

Treatment for malaria involves ⁢antimalarial drugs, which are prescribed ‍depending ⁢on the species of⁤ parasite and the severity of the infection. Early treatment is crucial to prevent life-threatening complications.

**Prevention:**

Preventing‍ malaria⁣ includes:

* **Using mosquito ‍repellents:** Apply repellents containing DEET, picaridin, or IR3535.

* **Wearing protective clothing:** Wear long ‌sleeves, pants, ‍and socks when mosquitoes⁣ are active.

*‍ **Using mosquito nets:** Sleep under‍ insecticide-treated mosquito nets.

* ‍**Antimalarial medication:** ⁢In areas where malaria is⁤ common, travelers can ‍take ⁢antimalarial medication as a preventive ‍measure.

**Impact:**

Malaria is⁣ a major public health concern, particularly in vulnerable populations ‍such⁤ as children⁣ and pregnant women. According ‍to the World Health Organization ‌(WHO),‌ there were‌ an estimated 241 million cases of‍ malaria in 2020, ⁤resulting ⁢in over 627,000 ⁤deaths.
