What are the characteristics of yellow fever in Congo

According to foreign media reports, the World Health Organization said Tuesday that 21 people in the Democratic Republic of Congo have died of yellow fever, some of them in neighboring Angola.

The yellow fever outbreak in Angola has killed 225 people and infected 1600 people, the report said.

It was previously reported that the outbreak in Angola began in Luanda, the capital. Health experts say the outbreak has been linked to the collapse of health services and waste accumulation in Luanda and other cities, which has led to a significant increase in the number of mosquitoes carrying the virus. At present, 450000 people have been vaccinated in Luanda, the capital of Angola, while the target population is nearly 1.6 million.

At the same time, the country's health officials point out that cases of malaria, cholera and chronic diarrhea are also increasing.

Who says there is a higher risk of further spread of yellow fever here, given the number of people who regularly travel between the DRC and Angola. Yellow fever is really terrible. Once you have it, you can't find it in time, if you don't treat it in time, it's terrible. Even serious cases can lead to death. So you must know the symptoms of yellow fever. Let's learn about it.


The body temperature decreased to normal after 7-8 days, the symptoms and proteinuria disappeared gradually, but the fatigue lasted for 1-2 weeks or even several months. In this period, we still need to pay close attention to the heart condition. Generally, there is no sequela.

Poisoning period

Generally, it starts on the 4th day of the course of disease. Some cases may have a short period of symptom relief (from a few days to one day). The body temperature slightly drops and rises again, which is saddle shaped. This period still has the high fever and the heart rate slows down, the jaundice deepens, the yellow fever therefore gets the name. The patient was apathetic, pale and vomited frequently. Proteinuria was more significant with oliguria. The prominent symptoms of this period are bleeding phenomena such as epistaxis, skin ecchymosis and ecchymosis, gastrointestinal tract, urinary tract and uterine bleeding. The vomit was black denatured blood. The heart often expands, the heart sounds weaken, and the blood pressure is low. Severe patients may appear delirium, coma, obstinate hiccup, urination and so on, accompanied by a large number of black vomitus. Most of the deaths occurred in this period.

Infection stage

Acute onset, accompanied by chills, followed by rapidly rising high fever, severe headache, systemic pain, significant fatigue, nausea, vomiting, etc. Vomitus was initially gastric content, and then bile like. The patient was anxious, blushing, conjunctival congestion, red tongue, dry skin. The heart rate increased in parallel with fever at the beginning, and then gradually changed to a relatively slow pulse. This period lasts for about 3 days. At the end of the period, there are mild jaundice, albuminuria, etc.

Yellow fever is very harmful, so we should pay attention to the spread of yellow fever in ordinary times. Don't go to crowded places in ordinary times to avoid being infected. Of course, when it's OK, we should go out for exercise more often to breathe fresh air.
