Malaria is a disease caused by a tiny organism called a parasite. When a mosquito bites a person who has malaria, the mosquito sucks up some of the person's blood, which contains the parasites. The parasites then travel to the mosquito's salivary glands, ready to be transmitted to the next person the mosquito bites.

Once the parasites enter a person's body, they make their way to the liver, where they multiply and mature. After a few days, the parasites leave the liver and enter the person's red blood cells, where they continue to multiply. This is where the real damage starts to happen.

As the parasites multiply inside the red blood cells, the cells eventually burst open, releasing more parasites into the bloodstream. This causes a number of problems, including anemia (a shortage of red blood cells), which can make a person feel weak and tired. The parasites can also cause inflammation in the blood vessels, which can lead to fever, chills, and headaches.

In some cases, the parasites can even stick to the walls of the blood vessels, blocking the flow of blood to vital organs like the brain, heart, and kidneys. This can lead to more serious symptoms, such as seizures, coma, and organ failure.

The good news is that there are medicines that can help treat malaria. By killing the parasites in the bloodstream, these medicines can help stop the disease from progressing and help people feel better. Additionally, there are many ways to prevent malaria, such as using mosquito nets and wearing insect repellent, so that people can avoid getting infected in the first place.

HIV is a virus that can make people very sick. It attacks a person's immune system, which is the system in our bodies that helps us fight off infections and diseases.

When someone is infected with HIV, the virus starts to attack certain cells in the immune system called CD4 cells or T-helper cells. These cells are important because they help the body fight off infections. HIV attaches to these cells and enters them, then it starts to reproduce itself inside the cells. This destroys the CD4 cells and makes it harder for the body to fight off infections.

Over time, as more and more CD4 cells are destroyed, the body becomes weaker and more susceptible to infections and other diseases. When the immune system is severely damaged, a person is said to have AIDS (Acquired Immunodeficiency Syndrome).

People with AIDS are at risk of developing opportunistic infections, which are infections that can take advantage of a weakened immune system. These can include infections like pneumonia, tuberculosis, and certain types of cancer.

While there is currently no cure for HIV/AIDS, there are medications available that can help people with the virus stay healthy and live longer. It is important to get tested for HIV if you think you might be at risk, and to practice safe behaviors to prevent the spread of the virus.

Tuberculosis (TB) is a type of bacterial infection caused by a germ called Mycobacterium tuberculosis. When someone gets TB, the bacteria can get into their body and make them sick.

When the bacteria get into the body, they can travel to the lungs and start to multiply. This can cause a lot of damage to the lungs and make it hard to breathe. It can also spread to other parts of the body, like the bones, joints, and brain.

The body's immune system tries to fight off the bacteria by sending white blood cells to the area. These cells can build up in the lungs and form small, round structures called granulomas. The bacteria can hide inside these granulomas and keep multiplying, which makes it harder for the immune system to get rid of them.

Over time, the damage to the lungs can get worse and the person can develop symptoms like coughing, fever, night sweats, and weight loss. TB can be very serious if it's not treated, but there are medicines that can help kill the bacteria and make people better.

I hope that helps you understand a little bit about how TB works!

Yellow fever is a disease caused by a virus called the Yellow fever virus. When the virus enters the body, it can cause a variety of symptoms that can range from mild to severe.

The virus is typically spread by a type of mosquito called the Aedes aegypti mosquito. When the mosquito bites a person who is infected with the Yellow fever virus, the virus can enter the mosquito's body and then be transmitted to another person when the mosquito bites them.

Once the Yellow fever virus enters the human body, it can infect cells in various organs such as the liver, kidneys, and heart. The virus can then cause damage to these organs, leading to a variety of symptoms such as fever, headache, muscle pain, and nausea.

In severe cases, the virus can cause a condition called hemorrhagic fever, which can cause bleeding from the nose, mouth, and eyes. This can be a life-threatening condition and requires immediate medical attention.

To prevent Yellow fever, it is important to avoid mosquito bites by wearing long-sleeved clothing, using insect repellent, and sleeping under mosquito nets. Vaccination is also available and is the most effective way to prevent Yellow fever.

Lassa fever is caused by a virus called Lassa virus. When this virus enters the body, it can cause different types of symptoms such as fever, headache, muscle aches, vomiting, diarrhea, and bleeding from different parts of the body.

The virus enters the body through contact with the urine or feces of infected rodents or through contact with the blood or bodily fluids of infected humans. Once inside the body, the virus multiplies rapidly and can invade different organs such as the liver, spleen, and kidneys.

The immune system tries to fight off the virus, but in some cases, it can actually make things worse by causing an excessive immune response. This can lead to inflammation and damage to different organs.

In severe cases, Lassa fever can cause bleeding from different parts of the body, such as the nose, mouth, and rectum. This happens because the virus can damage blood vessels and interfere with the body's ability to form clots.

Treatment for Lassa fever usually involves supportive care, such as fluids and medications to manage symptoms. In more severe cases, antiviral medications may be used. Prevention measures include avoiding contact with rodents and practicing good hygiene, such as washing hands regularly.
