What is the impact of climate change on malaria?

Hello,

Welcome to iCliniq.com.

I read your query and can understand your concern.

Yes, certain regions and populations are more vulnerable to mosquito-borne diseases due to climate change. Warmer temperatures and altered rainfall patterns can expand the geographical range of mosquitoes that carry diseases like malaria, dengue fever, zika virus, and chikungunya.

Populations in tropical and subtropical regions, where these diseases are already prevalent, are at higher risk due to increased mosquito activity and longer transmission seasons. Additionally, marginalized communities with limited access to healthcare, proper sanitation, and mosquito control measures are more vulnerable.

Climate change also affects socio-economic factors such as housing conditions and water management, which can influence the proliferation of mosquito breeding sites and increase disease transmission.

Efforts to mitigate climate change and implement effective mosquito control strategies, alongside improved healthcare infrastructure and public health education, are essential in reducing the impact of mosquito-borne diseases on vulnerable populations.

Cause:

Plasmodium species, an obligate intracellular protozoon using the mosquito as its vector, permeates the tropical and subtropical world.

Symptoms:

Typically beginning with a flu-like illness, the hallmark symptom of malaria is its paroxysmal fever, which can last up to 10 hours at a time. The classic description is a quartan (every 72 hours) or tertian (every 48 hours) fever periodicity synchronized with Plasmodium merozoites bursting from red blood cells during malaria’s asexual erythrocytic phase. These paroxysms occur with abrupt cold “chills” that transition after about an hour to profuse sweating, high fever, headache, malaise, and myalgias.

Diagnosis:

From thick and thin blood smears by pathologists.

Treatment usually consists of pharmacotherapy:

1. Artemether and Lumefantrine combination(antimalarials).

2. Atovaquone and Proguanil combination (antimalarials).

3. Quinine (antimalarials) (extended duration if infection acquired in southeast Asia) + Doxycycline (tetracycline antibiotics) (Doxycycline is preferred, but Tetracycline (broad-spectrum antibiotics) or Clindamycin (lincomycin antibiotics) are also options).

4. Mefloquine (antimalarials).

Prevention:

The R21 vaccine is the second malaria vaccine recommended by the WHO (World Health Organization), following the RTS,S/AS01 vaccine. I would suggest you do the following to prevent malaria:

1. Put screens on windows and doors.

2. Treat clothing, mosquito nets, tents, sleeping bags, and other fabrics with insect repellent.

3. Wear long pants and long-sleeved shirts to cover your skin.

4. The surface of the water may be coated with oils. The pupae and larvae are suffocated as a result. Kerosene or vegetable oil can be used for the same purpose.

5. Have fogging done in your area before the rainy season arrives, and repeat the process at regular intervals. The mosquitoes that may be hiding in places are helped by fogging.

6. Avoid letting water collect in coolers, tiny pits, or tires. These are conducive environments for mosquito development. It is best to make sure that storage areas do not have any standing water. If it rains, you should clean the surroundings immediately.

Kindly consult a physician, discuss with them, and start taking the medications with their consent.

I hope I have answered your question.
