Dengue: virus, fever, and mosquitoes

The most viral complaint spread only by certain mosquitoes is Dengue fever – substantially common in tropical areas around the world types of mosquitoes are Aedes aegypti or “dengue mosquitoes ”.

There are four types of dengue contagion that beget dengue fever – Dengue Types 1, 2, 3, and 4, People become vulnerable to a particular type of dengue contagion once. If other types of dengue are exposed can still get sick from it. Catching different types of dengue, indeed times piecemeal, increases the threat of developing severe dengue. Severe dengue causes bleeding and shock and can be life-changing.

Dengue mosquitoes only live and breed around humans and structures, and not in backcountry or pastoral areas. They suck during the day – substantially mornings and gloamings. Dengue mosquitoes aren’t born with dengue contagion in them, but if one bites a sick person having the contagion in their blood, that mosquito can pass it on to another mortal after about a week. With the passage of time for the contagion to multiply in the mosquito it’s a sign, “only senior womanish mosquitoes transmit dengue fever.” The mosquitoes remain contagious for life and can infect several people. Dengue doesn’t spread directly from person to person.

Symptoms & Signs

Classic dengue fever, or “break-bone fever, ”is characterized by the acute onset of high fever 3 – 14 days after the bite of an infected mosquito. Symptoms include frontal headache, retro-orbital pain, myalgias, hemorrhagic instantiations, Arthralgias, low white blood cell count, and rash. This case may also have complained of nausea and loss of weight. When it presents, the Acute symptoms generally last about 1 week, but weight loss, malaise, and weakness may persist for several weeks. dengue infections high proportion of minimum or no symptoms did not produce, especially in children and those with no history of having a dengue infection.

Follow the Steps to take when seeing a suspected case of dengue fever

Step 1: Notify your nearest Public Health unit incontinently upon clinical dubitation.

Step 2: Take a comprehensive trip history and determine whether the case was acquired overseas or locally.

Step 3: To identify the correct diagnostic test note the date of onset of symptoms, as during the illness correct laboratory tests depend on when the blood sample is collected.

Another useful test is a full blood count. Cases frequently haven leukopenia and/ or thrombocytopenia.

Test Type	PCR	NS1 ELISA	1gM	1gG
Days after onset of symptoms	0 – 5 days	0 – 9 days	From day 5 onwards	From day 8 onwards

Step 4: Prepare personal protection advice.

The patient should stay in the screened area and have somebody stay at home to look after them.
The patient should use personal insect tolerant, particularly during hours of daylight to avoid mosquito bites.
All household members should use personal insect nauseating during daylight hours.

Inform family members or those people who are connected with the case who develop a fever to present instantly for diagnosis.

Preceding to discharge:

Tell patients to drink sufficient liquids and get rest.
Tell patients to take febrifuges to control their temperature. Children with dengue are at risk for febrile attacks during the feverish phase of the illness.
Warm patients avoid aspirin and anti-inflammatory medicines because they increase the risk of bleeding.
Monitor your patients’ hydration levels during the feverish phase of illness. Educate patients and parents about the dehydration sign and have them examine their urine output.
Assess hemodynamic level regularly by checking the patient’s heart rate, pulse pressure, capillary refill, urine output, and blood pressure. If patients cannot tolerate liquids orally, they may need IV fluids.
Perform platelet counts, hemodynamic assessments, and baseline hematocrit testing.
Continue to examine your patients closely throughout defervescence. The critical phase angle of dengue starts with defervescence and lasts 24 – 48 hours.
