  5. Dengue virus genomes find in the middle of a range of 11000 nucleotide bases that code for three other types of proteins – E, C, M. These proteins help to form particles of the virus and also form 7 other types of proteins, namely, NS5, NS4a, NS2b, NS1, NS2a, NS3, NS4b. Most of these proteins found in infected host cells where replication of the virus occurs.
  6. DENV-1, DENV-2, DENV-3, and DENV-4: – Any one of these 4 viruses can cause dengue fever. These are actually 4 serotypes of dengue virus.

Precautions from Dengue

  1. In 2016, the World Health Organization also produced vexing for dengue called Sanofi Pasteur Dengvexia (CYD-TDV). Where dengue epidemics spread, it gives to people between 9 to 45 years of age.

  3. The World Health Organization has said that applying vexing is not so effective, for this it is necessary to control the mosquito population.

Diagnosis

  1. Dengue is recognized only by the symptoms of dengue and the patient has a history of travelling to check his travel. So that the doctor can find out if he has visited any dengue affected area.
  2. However, even after all this, the doctor instructs to get blood and other clinical tests done. The reason for this is that many other diseases like leptospirosis, typhoid, yellow fever, scarlet fever, Rocky Mountain spotted fever, meningococcemia, malaria, chikungunya, food-poisoning and many other diseases are closely related to it.
  3. In such a situation, if the patient has a terrible 104 Fahrenheit fever and the doctor is unable to understand from the initial examination, then further tests do identify dengue and distinguish it from other diseases.
  4. Most physicians conduct a complete blood test (CBC). In which the number of RBCs presents in the blood as well as platelets and white blood cells such as monocyte, basophils, eosinophils, and basophils also know. Decreasing the number of platelets and white blood cells indicates the possibility of dengue.
  5. Apart from this, spinal tapes also use along with blood culture and urine culture in the event of headaches so that there can a differentiation between dengue and other diseases.
  6. The immunoglobin M-based test (MAC-ELISA assay) can also use to test dengue fever. However several other tests are also available which are based on the immunological response of the patient’s dengue virus. Such as immunoglobins-ELISA (IgG-ELISA), dengue viral plaque reduction test and PCR test are the main ones. dengue fever symptoms

Transmission

  1. It spreads by mosquitoes of the species named Aedes aegypti. It spreads when a mosquito has bitten a patient first. And then has bitten a healthy person and transported the virus of dengue to that healthy blood as well.
  2. These mosquitoes are most commonly found in the latitude of 35 degrees south and 35 degrees north. Aedes mosquitoes attack in the morning and evening. Humans are like a host for this, even a single bite of a mosquito creates the possibility of disease. However, due to the presence of dengue virus in the patient’s blood. It can spread from infected blood or from organ donation.
  3. The probability of this disease prevails in children under 10 years of age. It was observed that the death rate in children due to dengue fever varies from 6 to 30%. And the chances of death due to dengue in children less than one year increase.

Treatment

Doctors avoid the use of non-steroidal anti-inflammatory agents (NSAIDs) such as aspirin, ibuprofen. And other NSAIDs for the treatment of dengue as the dengue virus has tendencies to haemorrhage. And NSAID may further increase this snowfall. Another acetaminophen (Tylenol), codeine, and other agents that do not contain NSAID are used for this.

The patient may need treatment in the hospital in the event of more severe dengue-like conditions such as hemorrhagic and shock syndrome. Requiring additional supportive treatment, in which the patient is in urgent need of IV fluid hypertension, blood transfusion. Platelet transfusion, blood pressure support, and other intensive care
