Symptoms of Malaria
  • The Plasmodium parasite, which causes malaria, infects female Anopheles mosquitoes that bite people and spreads the disease to them. The most harmful Plasmodium species is Plasmodium falciparum, which is one of numerous different kinds.
  • Both people and mosquitoes serve as hosts in the complicated life cycle of malaria parasites. The parasites enter the circulation and go to the liver after being bitten by an infected mosquito, where they mature and reproduce. The parasites eventually infect red blood cells, which results in the malarial symptoms that are so well known.

Transmission of Malaria

  • The main method of spreading malaria is via the biting of infected mosquitoes. When female Anopheles mosquitoes feed on human blood, they spread Plasmodium parasites to people. When a person gets bitten by a mosquito, the parasites in its saliva enter their bloodstream, which is when the transmission happens.
  • It’s crucial to understand that malaria cannot be passed from person to person. In order for the transmission process to take place, mosquitoes must act as intermediary hosts.

Common Symptoms of Malaria

Depending on the type of Plasmodium involved and the person’s immunological response, malaria symptoms might change. However, a few widespread signs include:

  • extreme fever
  • shivering and chills
  • Sweating
  • Headache
  • muscle pain
  • Fatigue
  • nausea and diarrhoea

Malaria can have serious side effects, including organ failure, convulsions, and even death. If you encounter these symptoms, you must contact a doctor very once, especially if you just visited a region where malaria is common.

Diagnosis of Malaria

Blood samples are examined for the Plasmodium parasite during the diagnosis of malaria. Different diagnostic techniques are employed, such as:

  • Microscopy: To find the presence of malaria parasites, a qualified technician looks at a blood smear under a microscope.
  • Rapid Diagnostic Tests (RDTs): These examinations look for certain proteins produced by the malaria parasite in a sample of blood. Fast findings are provided by RDTs, which are especially helpful in remote locations without access to microscopes.

For effective treatment and to differentiate malaria from other febrile disorders, a precise diagnosis is necessary.

Treatment Options for Malaria

The kind of Plasmodium, the degree of the infection, and the location all affect how effectively malaria may be treated. The main objectives of therapy are symptom relief and parasite removal from the patient’s body.

Typical antimalarial drugs consist of:

  • The most effective treatment for uncomplicated malaria, which is brought on by Plasmodium falciparum, the deadliest variety of the parasite, is artemisinin-based combination therapy (ACT). They combine artemisinin derivatives with other antimalarial medications.
  • To achieve total parasite eradication and avoid the emergence of medication resistance, it is crucial to finish the whole course of therapy as advised by a medical practitioner.

Prevention of Malaria

Controlling mosquito populations and taking human safety precautions are both necessary for malaria prevention. Following are a few effective preventative techniques:

  • Insecticide-treated bed nets, indoor residual spraying, and environmental management to get rid of mosquito breeding grounds are only a few of the steps in the process of controlling mosquito populations.
  • Personal defence strategies: People can defend themselves against mosquito bites by using insecticide-treated bed nets, donning long sleeves and pants, slathering on insect repellent on exposed skin, and taking antimalarial drugs while visiting high-risk locations.

Malaria and Travel

Visitors to regions where there is a high risk of malaria transmission should take steps to avoid getting sick. It is essential to obtain pre-travel advice from medical experts or travel clinics before leaving on a trip. They may tell travellers on the particular malaria dangers present in the area and suggest suitable preventive measures, such as antimalarial drugs.

The likelihood of getting bitten by mosquitoes when travelling may also be considerably decreased by utilising bed nets, insect repellents, and wearing protective clothes.


Symptoms of Malaria

Malaria in Children

Children’s undeveloped immune systems make them especially susceptible to malaria. They are more susceptible to serious consequences and have lower infection resistance. In order to avoid complications and lower death rates, it is essential to diagnose and treat children with malaria as soon as possible.

The prevalence of malaria in children can be significantly decreased by preventative interventions including the use of insecticide-treated bed nets and intermittent preventive medication.

Malaria and Pregnancy

Both the mother and the foetus are significantly at danger from malaria during pregnancy. Serious malaria can affect pregnant women more easily, and consequences including maternal anaemia, low birth weight, early birth, and even miscarriage are possible.

Pregnant women in malaria-endemic regions should take preventative precautions to safeguard themselves and their unborn children, including utilising bed nets, taking antimalarial drugs as directed by healthcare experts, and seeking early diagnosis and treatment for any symptoms.

Complications Associated with Malaria

Malaria can lead to various complications, particularly if left untreated or if the infection is severe. Some complications include:

  • Cerebral malaria: A severe form of the disease that affects the brain, leading to coma, seizures, and neurological damage.
  • Severe anemia: Malaria can cause the destruction of red blood cells, leading to a decrease in hemoglobin levels and impaired oxygen delivery.
  • Respiratory distress: Severe malaria can affect lung function and lead to breathing difficulties.
  • Kidney failure: In some cases, malaria can cause kidney damage and impaired kidney function.
  • Liver problems: Malaria can also affect liver function, leading to jaundice and other liver-related complications.

Prompt diagnosis, treatment, and supportive care are crucial in preventing and managing these complications.

Malaria Vaccines

In order to offer long-term protection against the illness, efforts are being made to create efficient malaria vaccines. There are several vaccine possibilities being explored, and several have shown promise in clinical studies.

RTS,S/AS01, commonly known as Mosquirix, is one of the most cutting-edge malaria vaccines. It has showed some promise in preventing malaria in young infants, and several malaria-endemic nations are considering testing it out.

Together with current preventive and control strategies, vaccination has the potential to drastically lower the burden of malaria on a worldwide scale.


Malaria Research and Global Efforts

Worldwide, malaria continues to pose a serious threat to public health, and major research is being done to better understand the condition and create fresh approaches to its treatment and prevention. Global campaigns like the Roll Back Malaria Partnership and the Global Malaria Programme of the World Health Organisation seek to coordinate efforts and improve malaria control and eradication programmes.

For a future free of malaria, investments in research, cutting-edge technology, and capacity-building are crucial.

Malaria and Climate Change

By changing temperature and rainfall patterns, which affect mosquito breeding habitats and distribution, climate change can have an impact on the transmission of malaria. Research on the effects of climate change on malaria is continuing.

The area where malaria transmission can occur may be expanded as a result of temperature and rainfall changes that favour mosquito breeding. To create effective control and preventive techniques that can adjust to the changing climate, it is essential to understand these dynamics.

Malaria in Developing Countries

By changing temperature and rainfall patterns, which affect mosquito breeding habitats and distribution, climate change can have an impact on the transmission of malaria. Research on the effects of climate change on malaria is continuing.

The area where malaria transmission can occur may be expanded as a result of temperature and rainfall changes that favour mosquito breeding. To create effective control and preventive techniques that can adjust to the changing climate, it is essential to understand these dynamics.People in underdeveloped nations, where resources for prevention and treatment may be scarce, are disproportionately affected by malaria. These areas frequently have the highest rates of the illness and have difficulty putting in place effective malaria control strategies.

In order to lessen the impact of malaria in poor nations, international cooperation, greater investments in healthcare infrastructure, and improvement of healthcare systems are crucial. Increasing access to diagnostics, antimalarial drugs, insecticide-treated bed nets, and other preventative measures falls under this category.



Malaria continues to be a global health concern, affecting millions of people every year. Timely diagnosis, prompt treatment, and comprehensive preventive measures are key in combating the disease. Through ongoing research, global efforts, and individual awareness, we can work towards a world free from the burden of malaria.
