Malaria Persistent (M. Stabilis)

“Persistent” malaria (M. stabilis), or M., is an epidemiologically interesting variant of malaria, characterized by a stable incidence rate without significant fluctuations over the years. This phenomenon may be due to the presence of collective immunity to the pathogen, which is formed in the population after suffering from malaria.

Persistent malaria, also known as endemic or permanent, is one of the most common forms of the disease in the world, especially in tropical and subtropical regions. It is caused by protozoan parasites of the genus Plasmodium, which are transmitted through the bites of Anopheles mosquitoes.

Persistent malaria is characterized by the following symptoms:

1. Stable incidence rate: There has been a stable incidence rate of malaria for many years without significant fluctuations. This may be due to a decrease in population migration or a lack of new cases of infection.
2. Pronounced herd immunity: a population that frequently encounters malaria develops immunity to the parasites. This allows them to better tolerate the disease and reduces the risk of re-infection.
3. Resistant strains: Malaria pathogens are able to adapt to environmental conditions and develop resistance to drugs. This makes treatment difficult and can lead to repeated cases of the disease.
4. Prevalence in warm climates: Persistent malaria is typically found in tropical and subtropical climates where high temperature and humidity encourage mosquito breeding and transmission.
5. Risk of complications: Long-term malaria can lead to serious complications such as anemia, kidney failure and other health problems.

Treatment of persistent malaria requires the use of special drugs, which may be ineffective in the case of resistant strains of parasites. In addition, preventive measures such as mosquito control and personal hygiene should be carried out.

And now, in our country, we have what has always been there: in Russia, WHO has recorded an outbreak of imported malaria. This does not apply to those people who just arrived and settled there, this applies to those who lived for years, gathered friends and walked around Moscow.

The important thing about malaria is blood poisoning. If we are vacationing somewhere in Africa or Asia, this blood could be from mosquitoes that transmit malaria. Our body notices that the blood has been attacked and produces antibodies to protect us. How do they produce antibodies? After a mosquito bite, the malaria parasite multiplies in the mosquito's body, and over time it turns into a so-called oocyst. This oocyte is shaped more like small snowballs on the road in winter, and is already weakened (1).

When a person becomes healthy, his body can destroy part of the parasite lying there, deep in the cells. Sometimes these cells dissolve very slowly, and sometimes they do not dissolve at all. As a result, a person sometimes continues to get sick because the parasite survives in skin cells and other places and manifests itself when the ambient temperature is warm. These conditions can include several things: high body temperature, low humidity, etc. When people spend a long time in hot, humid
