What is Dengue Fever?
This summer, "dengue fever" outbreak suddenly in many places around the world, causing serious panic.
So what exactly is "dengue fever"?
Dengue fever is an infectious disease, as its name suggests, is an acute insect-borne infectious disease caused by dengue virus infection.
Clinical dengue symptoms can involve multiple systems throughout the body, and its onset is closely related to factors such as season, climate, and environment.
How is dengue fever transmitted?
Although dengue fever is a contagious disease, it does not spread from person to person.
The only way it can be transmitted is when a susceptible person is bitten by a mosquito carrying the dengue virus.
Dengue fever mainly exists in tropical and subtropical regions where the temperature is relatively high and the rainfall is relatively high.
Dengue outbreaks generally do not occur in areas with cooler temperatures or drier climates and less rain.
Which groups are susceptible to dengue fever?
Since being bitten by dengue mosquitoes will catch dengue fever, will all people get dengue fever after being bitten by dengue mosquitoes?
of course not.
In affected areas, all people can be infected with dengue virus, but dengue virus is more likely to infect young children and children.
In addition, the elderly, pregnant women, and people with long-term chronic diseases, such as diabetic patients, are also susceptible groups.
Due to the relatively weak immune function of these people, they have poor resistance to various pathogenic factors. Once bitten by mosquitoes carrying dengue virus, the virus enters the body and cannot be cleared by the immune system in time, and they will become sick.
People working in the jungle are also susceptible to dengue virus. They are more likely to be bitten by mosquitoes, and although the individual's immune function is better, the chance of being infected increases accordingly.
To sum up, the dengue virus is more likely to spread among the following factors:
1. Seasonal factors
The prevalence of dengue fever has a distinct seasonality. In the rainy season, due to the humid environment, mosquito breeding accelerates, the chance of people being bitten by mosquitoes increases, and they are more likely to be infected with diseases;
2. Regional factors
The incidence is generally higher in tropical and subtropical regions with more rainfall. Especially people who live, travel or work in rural areas, fish ponds, and jungles are more likely to get sick;
3. Individual factors
The lower the immunity, the weaker the ability to resist the virus invasion, and the easier it is to be infected. People with chronic diseases such as diabetes, severe anemia, and tuberculosis have weak immune functions and are also prone to illness.
