Can people who return from Africa with malaria transmit it to others they don t get sick until they

Malaria is not contagious, so there is no need to worry about human beings passing it on to each other. Malaria is an arbo-borne disease caused by the Plasmodium parasite through the bite of Anopheles mosquitoes. Infection through the bite of Plasmodium mosquitoes or transfusion of blood from a person with Plasmodium.

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 a parasitic disease caused by the parasite Plasmodium, which is more common in summer and autumn.

**Malaria should be treated with antimalarial drugs such as chloroquine, quinine, artemisinin, etc. Malaria remains one of the biggest killers of humanity today. The word "malaria" means "bad air" in Latin, and even the ancient Romans realized that miasma in certain swampy areas should be avoided.

However, malaria is not caused by germ-laden air, but by mosquitoes that breed in immobile water. A parasite the size of a red blood cell has been found in malaria patients. How does it invade the human body?

It is first found in the stomach of the mosquito. After breeding there, the larvae invade the mosquito's salivary glands. When a mosquito bites, the parasites in the saliva enter the body's bloodstream.

After a few weeks, the infected person will develop the fever and chills characteristic of malaria and fall ill. This fever is transient and reverse. Only female mosquitoes bite and suck blood, so only female mosquitoes transmit malaria.

Many Chinese working hard in Africa die from this disease every year.

I've been to Africa and learned about malaria, so it won't spread, don't worry, malaria still needs dirty water and environment, and it's long gone in China.

Analysis: Hello, malaria is very contagious, it is recommended that you describe the people you have been in contact with to see if anyone has symptoms.

Suggestions:

Before going abroad, authoritative experts warned the Chinese team members that the probability of not suffering from malaria is very small for Chinese people who have stayed in Africa for more than one year. At first, they were a little unconvinced, but when they arrived in Liberia, they found that the mosquitoes that spread falciparum malaria here were very good.

They are small, silent, piercing hard, fleeing so fast that they are extremely difficult to detect. Coupled with the fact that 80 per cent of patients admitted to the hospital suffer from falciparum malaria, the chance of transmission is greatly increased. The disease is said to kill an average of one child under the age of 5 every 30 seconds in Africa.

As far as I know, malaria is not only present in Africa, but also very numerous, especially in sub-Saharan Africa, where the incidence of malaria is more than 85%.

I remember when I was a sophomore in parasites, my teacher used to say that malaria causes several children to die of malaria every minute in Africa.

In addition, if a person returning from a tourist tour from Africa has symptoms that are difficult to diagnose with a high degree of fever, the occurrence of malaria is largely considered.

Malaria occurs for a number of reasons, not the least of which is the displacement of people after the war.

In addition, the infection rate of pregnant women is also very high, and many are infected with malaria and AIDS at the same time.
