                        MALARIA 

Causes:

Malaria is caused by the Plasmodium parasite, which is transmitted to humans through the bite of infected female Anopheles mosquitoes. There are several species of Plasmodium that can cause malaria in humans, with Plasmodium falciparum and Plasmodium vivax being the most common and dangerous.


Transmission:

The transmission occurs when an infected mosquito bites a person and injects the parasite into the bloodstream. Additionally, malaria can also be transmitted through blood transfusions, organ transplants, or from a mother to her unborn child.


Symptoms:

Symptoms of malaria usually appear 10–15 days after the infective mosquito bite. The initial symptoms are flu-like and can include:

- Fever

- Chills

- Sweats

- Headache

- Nausea

- Muscle aches

If not treated promptly, malaria can progress and cause severe complications, including:


Effects:

- Severe anemia due to the destruction of red blood cells

- Cerebral malaria, which can lead to coma, seizures, and neurological damage

- Organ failure, particularly of the kidneys or liver

- Pulmonary edema

- Hypoglycemia

- Death


Prevention:

Preventive measures include:

- Using insecticide-treated bed nets

- Wearing protective clothing that covers the arms and legs

- Using insect repellent

- Taking antimalarial medications when traveling to areas where malaria is prevalent


Treatment:

The treatment for malaria depends on the type of parasite causing the infection, the severity of the disease, and the patient's age and health status. Commonly used antimalarial drugs include:

- Chloroquine

- Artemisinin- based combination therapies (ACTs)

- Quinine

- Mefloquine


Global Impact:

Malaria is a major global health problem, particularly in sub-Saharan Africa. According to the World Health Organization (WHO), in 2019, there were an estimated 229 million cases of malaria worldwide, resulting in approximately 409,000 deaths. Children under the age of 5 are the most vulnerable population group, accounting for more than two-thirds of all malaria deaths.


Efforts to control and eliminate malaria include:

- Vector control through mosquito nets and indoor residual spraying

- Early diagnosis and prompt treatment

- Development of new antimalarial drugs and vaccines

- Public health education and community engagement


Conclusion:

Malaria is a life-threatening disease caused by the Plasmodium parasite, transmitted through the bite of infected mosquitoes. It is a major global health problem, particularly in tropical and subtropical regions. Prevention, early diagnosis, and prompt treatment are crucial in reducing the burden of malaria and preventing complications and death.

Most likely, you're not getting enough fibre. Here's how to get more.

New study shows that fibre can help keep your brain healthy as you age. It also has other surprising benefits, but most of us aren't getting enough of it. Fibre is like the middle child of all the macronutrients. Carbs and fats don't get that much attention, but protein does. But fibre isn't thought about until something goes wrong. But if you talk to gut experts, they'll tell you that it's the quiet performer that starts a huge number of biochemical chain reactions that are important for long-term health and, of course, routine. We already know that getting enough fibre is good for your gut system, helps you control your weight, lowers your risk of heart disease, and keeps your blood sugar levels in check. Now, a new study shows that taking a fibre pill every day might help people over 60 keep their brains healthy. The study from King's College London was released in the journal Nature Communications. It found that people did better on cognitive tests after tak...

CDC Sends New ‘Health Alert’ Over Bird Flu in the US

CDC Sends New ‘Health Alert’ Over Bird Flu in the US Exterior of the Center for Disease Control (CDC) offices in Atlanta on Oct. 13, 2014. (Jessica McGowan/Getty Images) The U.S. Centers for Disease Control and Prevention (CDC) sent an alert on April 5 to state health departments and doctors after a human bird flu infection in a Texas dairy farm worker was confirmed earlier this month. In a “health alert network” advisory, the federal agency said that health care providers should be aware of its “updated recommendations” on “instructions for infection prevention and control measures, using personal protective equipment (PPE), testing, antiviral treatment, patient investigations, monitoring of exposed persons” such as individuals who have been “exposed to sick or dead wild and domesticated animals and livestock with suspected or confirmed infection” with H5N1 avian influenza. For doctors and health care workers, they “should consider the possibility of” bird flu in people “showing si...

World Health Day emphasises the necessity of universal access to quality healthcare.

The World Health Organization (WHO) is commemorating World Health Day on April 7 with the theme 'My Health, My Right' in pursuit of health justice and universal access to quality healthcare. This year's theme is particularly relevant in light of the rising global health concerns, emphasizing the importance of protecting every individual's fundamental right to health, according to healthcare specialists. They called on us to reaffirm our commitment to promoting everyone's fundamental right to health. "By fostering inclusive healthcare systems, prioritizing preventive measures, fostering and incentivizing an active lifestyle and advocating for environmental stewardship, we can pave the way towards a healthier and more resilient future for generations to come," they went on to say. Across the globe, billions of people's right to health is jeopardized by a variety of risks, ranging from environmental disasters to a lack of healthcare access. The toll ...
