Man returns home with a high fever of 39.5C: not the first fatal infectious disease in Africa

According to the WHO, there are still 228 million cases of malaria worldwide in 2018. Malaria is the number one of Africa’s three leading diseases.

So far in 2017, there have been no new cases of indigenous malaria in china for three consecutive years.

However, in recent years, with the number of people working, doing business, traveling and participating in international exchange activities in overseas areas, especially in Africa and Southeast Asia, there have been nearly 3,000 cases of malaria imported from abroad each year, and the main source of malaria cases imported from abroad.

And once infected, if left untreated, it can be life-threatening.

What disease is malaria?

Malaria, commonly known as “swinging”, “spleen cold”, “hot and cold disease”, is caused by human malaria parasite infection caused by insect-borne infectious diseases.

Malaria may have existed in early humans as early as 500,000 years ago, according to studies.

Depending on the type of malaria parasite, malaria can be divided into interstitasy malaria, ovoid malaria, three-day malaria and plasumuchl.

Malaria is common in summer and autumn, but can occur all year round in tropical and subtropical regions and is prone to epidemics.

On 27 October 2017, the World Health Organization’s International Agency for Research on Cancer (IATA) published a preliminary list of carcinogens, malaria in the list of class 2A carcinogens.

How does malaria spread?

Mosquito bites: Mosquito bites of females infected with malaria parasites are the main route of malaria transmission.

Although mosquito bites do not transmit hepatitis B, AIDS and other viruses, but if the mosquito body carries malaria parasites, when it bites people into the body saliva, it is easy to spread.

Blood transmission: An infection is carried into the blood of a person with malaria parasite.

Mother-to-child transmission: Pregnant women with malaria or asymptomatic infections can infect the fetus through the placenta.

Who is susceptible to malaria?

At present, malaria endemic areas are mainly distributed in Africa, Southeast Asia, the Eastern Mediterranean, the Americas, among which sub-Saharan Africa and South-East Asia malaria is highly prevalent.

Malaria is generally susceptible to people, especially the elderly, pregnant women, infants and young children, people with low immunity, and tourists or migrant workers who travel to affected areas.

Once you have malaria, you should pay attention to these symptoms.

What are the symptoms of malaria?

The onset of malaria is “incubation period – chill period – fever period – sweat period”.

Typical clinical symptoms of adults are periodic seizure schills, high fever, a large amount of sweating, accompanied by headache, fatigue, loss of appetite and sore limbs.

Malaria, three days of malaria

The early intervals of malaria and three-day malaria patients can be irregular, and gradually after multiple seizures, and there is no obvious pattern of plasintos.

Plasmodium falciparum

Plasmodium falciparum is more dangerous, can appear serious anemia, acute renal failure or coma and other symptoms, causing great harm to the human body, such as not timely diagnosis and treatment, or even life-threatening.

Infant malaria fever is irregular, before the fever can be no chill performance, high fever is often prone to convulsions.

How can I distinguish between malaria and new coronary pneumonia?

At present, the outbreak of new coronary pneumonia is raging around the world, in the early stages of the disease, malaria and the clinical manifestations of new coronary pneumonia have many similarities, how should the two diseases be distinguished?

How can I prevent it?

1, anti-mosquito anti-mosquito, to avoid mosquito bites, is the most important means to prevent malaria

Try to avoid outdoor activities during the peak mosquito activity (dusk and night), spray mosquito repellent or mosquito scent in your bedroom before bedtime, and use mosquito nets when you sleep.

2, to eliminate malaria patients blood donation, do not use unknown blood products

Africa and South-East Asia are highly malaria-endemic areas and should be protected by personal protection, such as physical protection (e.g. wearing long pants or using mosquito nets) and chemical protection (e.g. use of drugs, mosquito repellent or preventive medicines).

3, planning travel or work and other occasions, pay special attention to personal protection

Travel to Africa or work to study people, if there is cold, fever, sweating and other symptoms should be timely initiative to seek medical treatment, medical treatment on the way to do a good job of personal protection, clinical diagnosis needs to find malaria parasites in blood smears.

In terms of vaccines, Mosquirix is the first malaria vaccine to pass a clinical trial phase, which has a preventive effect on malaria but has a low rate of protection.

In summary, malaria, although generally susceptible to human son, but it is also a preventable and treatable infectious disease, so do not have to panic.

Do a good job of protection, if the infection symptoms, must be timely medical treatment, so as not to cause serious consequences.
