The plant cells are exposed in a change of pressure liquid depending the quantity of solids that are inside and outside the cell.

Write a short note on malaria as a disease its causative, target organs symptoms and control.
anastassius [24]

Answer:

Explanation:Malaria is a life-threatening disease. It’s typically transmitted through the bite of an infected Anopheles mosquito. Infected mosquitoes carry the Plasmodium parasite. When this mosquito bites you, the parasite is released into your bloodstream.

Once the parasites are inside your body, they travel to the liver, where they mature. After several days, the mature parasites enter the bloodstream and begin to infect red blood cells.

Within 48 to 72 hours, the parasites inside the red blood cells multiply, causing the infected cells to burst open.

The parasites continue to infect red blood cells, resulting in symptoms that occur in cycles that last two to three days at a time.

Malaria is typically found in tropical and subtropical climates where the parasites can live.

What causes malaria?

Malaria can occur if a mosquito infected with the Plasmodium parasite bites you. There are four kinds of malaria parasites that can infect humans: Plasmodium vivax, P. ovale, P. malariae, and P. falciparum.

P. falciparum causes a more severe form of the disease and those who contract this form of malaria have a higher risk of death. An infected mother can also pass the disease to her baby at birth. This is known as congenital malaria.

Malaria is transmitted by blood, so it can also be transmitted through:

an organ transplant

a transfusion

use of shared needles or syringes.

Symptoms of Malaria

The symptoms of malaria typically develop within 10 days to 4 weeks following the infection. In some cases, symptoms may not develop for several months. Some malarial parasites can enter the body but will be dormant for long periods of time.

Common symptoms of malaria include:

shaking chills that can range from moderate to severe

high fever

profuse sweating

headache

nausea

vomiting

abdominal pain

diarrhea

anemia

muscle pain

convulsions

coma

bloody stools.

Diagnosis and Treatment : infected person is diagnosed and treated with ACT drugs.
