The 18 Main Symptoms of Dengue

The Main Symptoms of Dengue that many ignore and go unnoticed. In addition, dengue is an acute febrile illness caused by a virus, being one of the main public health problems in the world. It is transmitted by the Aedes aegypti mosquito, which thrives in tropical and subtropical areas. Currently, the vaccine is the best way to prevent dengue .
The World Health Organization (WHO) estimates that between 50 and 100 million people are infected with dengue annually in more than 100 countries on all continents except Europe. About 550,000 patients require hospitalization and 20,000 die as a result of dengue . There are four types of dengue,according to the four serotypes: DEN-1, DEN-2, DEN-3 and DEN-4. When a person has dengue , they have relative immunity against another serotype.

It is believed that the Aedes aegypti mosquito arrived in Brazil by slave ships, since the first appearances of the mosquito took place on the African continent. At the beginning of the 20th century, the doctor Oswaldo Cruz implemented a program to combat the mosquito, aiming to reduce cases of yellow fever . This measure even eliminated dengue in the country during the 1950s. According to the Ministry of Health, the first occurrence of the virus in the country, confirmed by laboratory tests, occurred in 1981-1982 in Boa Vista (PR).

However, dengue reoccurred in Brazil in the 1980s. Currently, the four types of viruses circulate in the country, with 587,800 cases of dengue recorded in 2014, according to the Ministry of Health.

Causes of Dengue: Dengue iscaused by an arbovirus of the genus Flavivirus. It is the most common arbovirus that affects humans, which is its vertebrate host. The dengue virus exists in four serotypes DEN-1, DEN-2, DEN-3 and DEN-4. The person with dengue serotype DEN-1 cannot, theoretically, be reinfected by this serotype, since the immune system creates defenses against this form of the disease. However, the same person can get type 2 (DEN-2) and possibly type 3 or 4. Note that the order may be different, the person may be affected first type 2 (or 3 or 4) and then type 1 etc. The same individual can therefore suffer from the 4 types of dengue more than 4 times from dengue. A person with dengue for the second time has a higher risk of developing a severe form of dengue ( dengue hemorrhagic fever). Vaccination would be adequate to prevent the complications of the disease, which is why several researchers around the world are working to find a vaccine against dengue .

Symptoms of Dengue: After the mosquito bite with the virus, symptoms usually manifest from the 3rd to the 15th day. This period is called incubation. The average duration of illness is five to six days. It is only after the incubation period that the following symptoms appear:, so check now The Top 18 Symptoms of Dengue.

Classic Dengue:

• high fever  with sudden onset.
• Headache .
• Pain behind the eyes, which gets worse with their movement.
• Loss of taste and appetite.
• Nausea and vomiting.
• Dizziness.
• Extreme tiredness.
• Measles-like patches and rashes on the skin, especially on the chest and upper limbs.
• Softness and pain in the body.
• Lots of bone and joint pain.

Dengue Hemorrhagic:  The symptoms of dengue hemorrhagic fever at the onset of the disease are the same as those of common dengue . The difference most often occurs when the fever ends  and the alarm signs begin to appear:

• Severe and continuous abdominal pain.
• Persistent vomiting.
• Skin pale, cold and clammy.
• Bleeding from the nose, mouth and gums.
• Drowsiness, agitation and mental confusion.
• Excessive thirst and dry mouth.
• Pulse rapid and weak.
• Breathing difficulty.
• Loss of consciousness.

Dengue Treatment:  The treatment of these 3 diseases are similar, with measures that involve pain relief and hydration. The indicated drugs are usually Paracetamol or Dipyrone, but these should only be used when recommended by the doctor. Aspirins should not be used because they increase the risk of bleeding.

When the symptoms of these diseases manifest, it is important to take the individual to a medical consultation because cases of Dengue , Zika virus and Chikungunya must be reported to the authorities and because complications can arise that compromise the individual’s life.

How to Avoid Dengue:  The period of greatest risk of contagion of dengue , Zika virus and chikungunya fever  is in the summer, especially during or after rainy days because Aedes Aegypt reproduces in clean and still water and the best way to avoid these diseases is by preventing the proliferation of the mosquito, eliminating all clean and stagnant water from houses, streets and businesses.
Another strategy, which can help prevent mosquito bites, is to eat foods rich in vitamin B1 , such as Ovaltine, brown rice and brewer’s yeast, or to take a supplement of this vitamin that you can buy at the pharmacy.
