Is it dengue fever? What is dengue fever

Dengue fever is an acute infectious disease caused by dengue virus and transmitted by Aedes mosquitoes (commonly known as Aedes versicolor). Dengue fever is not transmitted directly from person to person, nor is it transmitted by air or contact, and as of October 2019, there is no vaccine to prevent it.

Its incubation period is usually about 5-7 days, and it has the characteristics of rapid transmission and high morbidity. Because the disease is transmitted by mosquitoes, the epidemic has a certain seasonality, generally from May to November every year, and the peak is from July to September.

Dengue fever dēng gé rè

Name of the disease. An acute infectious disease in which pathogens are introduced into humans by the black spotted mosquito. The patient has general fatigue, fever, chills, headache and muscle aches, and ** rash and other symptoms.

It is also known as tengu fever and dengue fever.

Dengue fever is an acute viral illness caused by the dengue virus that spreads among people through mosquito bites. It does not spread directly from person to person through the respiratory tract, digestive tract, or contact.

The incubation period of dengue fever is 3 to 14 days, i.e. patients usually develop the disease within 3 to 14 days after the mosquito bite.

Main symptoms and signs: sudden onset of high fever, which generally lasts for 3 to 7 days, and the body temperature can reach more than 39. Three pains:

It is mainly severe headache, orbital pain, joint and muscle pain, and may have morbilly, scarlet fever, vitiligo, urticaria, etc. Rash with a positive arm test or petechiae, **, small bleeding from the gums and nasal cavity, fatigue, and gastrointestinal symptoms such as nausea and vomiting.

Dengue fever is an acute infectious disease caused by dengue virus and transmitted by Aedes mosquitoes, and patients and infected people are the main sources of infection. The clinical features are sudden onset, high fever, generalized muscle, bone marrow and joint pain, extreme fatigue, and rash in some cases.

Hello, dengue is an acute febrile illness caused by the dengue virus, characterized by fever, arthralgia, muscle pain, rash, swollen lymph nodes, and leukopenia.

At present, there is no definite and effective pathogen drug for this disease, and supportive and symptomatic measures are mainly taken. Patients should be detected as early as possible, isolated early, and treated as early as possible.

Dengue fever is the most common mosquito-borne virus infection worldwide and is mainly transmitted by the bite of Aedes albopictus (Aedes versicolor). The disease spreads quickly, and people often develop flu-like symptoms, sometimes progressing to a potentially fatal complication called severe dengue.

According to the World Health Organization (WHO), the global incidence of dengue fever has increased significantly in recent decades, and about half of the population is at risk of dengue fever. In China, Guangdong, Yunnan and other places have also had many outbreaks of Denge epidemics, causing serious public health problems.

At present, there is no specific drug for dengue fever, and it can only be prevented by mosquito control and other means for a long time. The development of an effective dengue vaccine is an important means of controlling dengue transmission.

Patients with dengue fever have a sudden onset of symptoms such as persistent fever, severe headache, retroorbital pain, muscle pain, and arthralgia, along with loss of appetite, nausea, vomiting, and rash.

However, the symptoms of dengue fever can be mild or severe, and in the early stage, it is similar to a cold and flu, and it is easy to misdiagnose, but a small number of patients will become seriously ill 3 to 5 days after the onset of the disease.

Like the elderly, pregnant women, children; Patients with underlying diseases such as diabetes, hypertension, coronary heart disease, liver cirrhosis, peptic ulcer, asthma, chronic obstructive pulmonary disease, chronic renal insufficiency, etc.; People with secondary infections and other groups are all high-risk groups that may develop severe disease.

Here is a special talk about the situation of secondary infection:

There are four serotypes of dengue virus: DENV-1, DENV-2, DENV-3, and DENV-4, all of which can infect humans. After being infected by dengue virus, the human body can develop long-lasting immunity to the same type of virus, but it cannot form effective protection against abnormal virus infection.

If the virus is reinfected with a different serotype or multiple serotypes, the body may develop an immune response, which can lead to severe clinical manifestations and even life-threatening.

According to the CDC, patients with dengue fever typically develop a high fever with at least two of the following symptoms:

1. Severe headache.

2. Severe eye pain (especially retroorbital pain).

3. Arthralgia.

4. Muscle pain or bone pain.

5. Rash. 6. Slight bleeding manifestations (such as nose or gum bleeding, or ecchymosis and petechiae, etc.).

7. Low white blood cell count.

Of course, it is still the old rule, do not self-diagnose according to the symptoms, and it is not that the above symptoms must be dengue fever, and you must go to the hospital for a comprehensive examination to be sure.

If dengue fever is not diagnosed, it is also necessary to pay attention to mosquito prevention to prevent dengue fever.
