Where is malaria distributed? What is malaria

According to the World Health Organization, about 100 million people worldwide were infected with malaria in 2019, and 10,000 of them died.

More than 90% of malaria cases worldwide are concentrated in Africa, among othersNigeria, Democratic Republic of the Congo, Tanzania, Niger, MozambiquewithBurkina FasoThese six countries account for 50% of the world's total cases.

Asia (India, Indonesia, Myanmar, Cambodia, Vietnam, Philippinesand other countries), the Eastern Mediterranean region (Afghanistan, Pakistanand other countries), the Western Pacific region (Papua New Guineaand other countries), the Americas (Brazil, Colombia, Venezuelaand other countries) are also endemic of malaria.

Current status of malaria epidemic in China:

As of 2020, there have been no local primary malaria cases reported in China for four consecutive years. Since 2006, Fujian Province has reported no locally acquired malaria cases for 15 consecutive years, and passed the national malaria elimination assessment in 2019.

However, for a long time, Fujian Province has a large number of business, work, and tourism people going to Africa, Southeast Asia, South America, etc., and about 100 imported cases are reported every year.

In the case of the widespread presence of the malaria vector, Anopheles sinensis, the prevention and control of imported malaria is still the focus and difficulty of the prevention and control of infectious diseases.

We're all going to have some people who are either me or you, and I don't want to have one person, and I have one person, me, mine.

Malaria is a severe, sometimes life-threatening tropical disease that is transmitted by parasites. Every year, 10,000 people die from the disease, many of them children in Africa.

Countries with warmer climates can lead to a proliferation of malaria parasites and mosquitoes that carry malaria parasites. These regions include sub-Saharan Africa, Southeast Asia, Latin America, and the Middle East.

Before you travel, check the Centers for Disease Control and Prevention (CDC)** to see if your destination is in an area with a high incidence of malaria. Travelers may need to take medication before, during, and after travel to reduce the likelihood of getting sick.

Why malaria is harmful to humans.

Malaria causes high fever, chills, and flu-like symptoms that can be life-threatening if not promptly**. The disease is caused by the parasite malaria, which is transmitted by the Anopheles mosquitoes.

Only female mosquitoes transmit the malaria parasite. When a mosquito bites a person who already has malaria, it sucks the person's blood, which contains the malaria parasite. When a mosquito bites the next victim, it injects the malaria parasite into the person's body. This is how malaria is transmitted.

Once the malaria parasites enter the body, they reach the liver, where they multiply. They invade red blood cells, which are important cells in the blood that carry oxygen. The malaria parasite enters the red blood cells, lays eggs, and then multiplies until the red blood cells burst.

Types of malaria.

There are five species of Plasmodium that infect humans, two of which are considered the most dangerous:

Plasmodium falciparum. This is the most common malaria parasite in Africa, and it is responsible for the highest number of malaria deaths in the world. Plasmodium falciparum multiplies quickly, causing severe blood loss and blockage of blood vessels.

Plasmodium vivax. It is the most common malaria parasite outside of sub-Saharan Africa, especially in Asia and Latin America. This malaria parasite becomes dormant and then becomes active again months or years after a mosquito bite and infects the bloodstream.

Symptoms of malaria usually begin to appear 10-15 days after being bitten by an infected mosquito. However, there are a few things to keep in mind:

Because these symptoms are very similar to those of a cold or flu, it can be difficult to tell what you have at first.

Malaria symptoms do not always appear within 2 weeks, particularly with Plasmodium vivax infection.

People who live in malaria-prone areas may develop lifelong partial immunity when infected.

Blood tests can confirm malaria.

In addition to high fever, chills, and sweating, other symptoms of malaria include:

Vomiting or a feeling of vomiting.

Headache and diarrhea. Fatigue, body aches.

Yellowing (jaundice) due to loss of red blood cells

Kidney failure.

Seizures. Confusion.

Malaria causes coma.

Children with severe malaria may be anemic, which is the loss of too many red blood cells. Affected children may also have difficulty breathing. Rarely, children develop cerebral malaria, which causes brain swelling and damage.

When should I see a doctor?

Considering that malaria would.

Malaria is an insect-borne disease caused by infection with the Plasmodium parasite through the bite of Anopheles mosquitoes or the transfusion of blood from a person with the malaria parasite. There are four types of Plasmodium parasites that live in humans, namely Plasmodium vivax, Plasmodium malariae, Plasmodium falciparum, and Plasmodium ovale. In our country, it is mainly Plasmodium vivax and Plasmodium falciparum; The other two are rare, and some cases imported from abroad have occasionally been seen in recent years.

Different Plasmodium parasites cause vivax malaria, malaria malariae, falciparum malaria and peripheryx ovale. The disease is mainly manifested by periodic and regular attacks, with chills, fever, and excessive sweating all over the body, which can cause anemia and splenomegaly after multiple attacks for a long time.

Malaria is an infectious disease, its transmission route is mosquito bites, malaria is divided into four types, there are called the three days of the disease. Malaria ovale and falciparum malaria have been sporadic cases in warm areas of our country. In places like Africa, where you are also going to a very serious infectious disease, people who travel to Africa will be advised to protect against mosquito bites.

Malaria is an insect-borne disease caused by the Plasmodium parasite through the bite of an Anopheles mosquito or the infusion of the blood of a person carrying the malaria parasite. There are four types of Plasmodium parasites that live in humans, namely Plasmodium vivax, Plasmodium malariae, Plasmodium falciparum and Plasmodium ovale. In our country, the main ones are Plasmodium vivax and Plasmodium falciparum, and the other two species are rare, and some cases imported from abroad can be seen in recent years.

Malaria is mainly manifested by periodic attacks, with chills, fever, and excessive sweating all over the body, which can cause anemia and splenomegaly after multiple attacks over a long period of time.

Malaria is a global acute parasitic disease caused by the parasite Plasmodium and transmitted primarily through Anopheles mosquitoes. Malaria was also known as miasma in ancient China and malaria abroad, which is a combination of the Italian words mala (bad) and aria (air). The disease is caused by the bite of Anopheles mosquitoes and the introduction of parasites such as malaria parasites into the body.

Malaria is characterized by periodic hot and cold episodes, splenomegaly, anemia, and various syndromes caused by damage to the brain, liver, kidneys, heart, intestines, and stomach. Between 3500 million people and 1 million 3 million people die from malaria each year, most of them children.

This infectious disease of the gastrointestinal tract.

A disease transmitted by Anopheles mosquitoes.

Malaria is a serious disease with chills and high fever as the main symptoms, which is transmitted to people through the bite of infected mosquitoes. At present, malaria has been effectively controlled in China, but malaria is still common in Africa, South Asia, Central America and South America.

Malaria is typically characterized by periodic episodes of flu-like symptoms (chills, high fever, muscle aches, fatigue, dry cough), but falciparum malaria usually does not have periodicity. People who are partially immune may not have any symptoms.

Plasmodium falciparum and Plasmodium knowlesi infections are the most dangerous forms of malaria, most of which can be cured with medications**, and may require exchange transfusion in severe cases**.

Preventing mosquito bites and taking preventive drugs correctly in advance are the main measures to prevent malaria. Pregnant women, children, the elderly, and people with weakened immune systems are at higher risk of severe malaria and should avoid traveling to these places.

Malaria is first and foremost a contagious disease, which is an insect-borne infectious disease caused by infection with Plasmodium parasites after being bitten by mosquitoes or transfused into the blood of a person with Plasmodium. In China, Plasmodium vivax and Plasmodium falciparum are more common, and they are more common from abroad, and can be transmitted through mosquito bites or transfusion of blood from people with malaria parasites.

Malaria infection usually occurs periodically, accompanied by chills, fever, sweating, anemia and splenomegaly. Moreover, it will affect liver and kidney function, and in severe cases, it will even be life-threatening, and the more dangerous complications at this time are anemia and splenomegaly. It is necessary to check the blood routine, stool routine, biochemical examination, liver and kidney function test, malaria parasite examination, as well as CT and bone marrow smear staining to check for malaria parasites, and the positive rate is still relatively high.

Malaria is a contagious disease caused by the parasite malaria. Symptoms appear on average 12 to 35 days after infection, and the typical symptoms are repeated alternating high fever, chills, and sweating, followed by splenomegaly, anemia, jaundice, etc. If detected in time, it is possible to use appropriate antimalarial drugs**.
