What is a Virus?

The virus is a Latin word meaning ‘poison’. It is a toxic organism that cannot live on its own but thrives inside living cells. The family of viruses is determined by their shape, genome structure, and spread.
The number of viruses on Earth is estimated in the billions. It is so small that it can only be seen under an electron microscope. The virus cannot survive alone but is a parasite, meaning it needs the help of another cell to survive.
Infections are microscopic pathogens that can infect a wide range of living organisms, including microbes, plants, and animals. The dengue infection, like other diseases, is a microscopic structure that can only replicate within a host biological organism.

What is Dengue Fever?

Dengue Virus

In the 1775’s, when a disease spread in Asia, Africa, and North America, in which the patient suddenly developed a high fever, followed by headache and joint pain, while some patients also had abdominal pain, bloody vomiting, and bloody patches. Complained. The patient suffered from the same disease for seven to ten days and eventually died. Panic spread among the people and people started migrating from these areas. When the doctors and physicians of that time did research on it, they found out that it is a special type of mosquito that can cause this disease by biting. Dengue fever kills white blood cells.
Dengue fever is a mosquito-borne sickness that primarily affects tropical and subtropical regions of the world. Dengue fever is characterized by a high fever and flu-like symptoms. Dengue hemorrhagic fever, a severe form of dengue fever, can result in major bleeding, a drop in blood pressure (shock), and death.
Dengue caused by mosquitoes can be fatal for the patient if not treated in the early stages. Dengue cases are also on the rise in different cities of Pakistan. The bite-induced disease attacks white blood cells and slowly destroys them. It is estimated that 400 million people worldwide are infected with dengue every year, of which 96 million are infected.

Symptoms of Dengue fever

Symptoms of Dengue fever

Symptoms of dengue usually appear 4 to 6 days after getting sick and usually last for 10 days. The first symptom of dengue fever is a severe headache which makes the patient feel unwell.   A symptom of dengue is a high fever, usually caused by a high fever of 104, 105, or higher, which causes abnormal changes in body temperature very quickly.

  • Fever that comes on quickly.
  • Headaches that are quite painful
  • Eyestrain
  • Joint and muscular discomfort that is excruciating.
  • Fatigue\nausea
  • Vomiting
  • Two to five days following the commencement of the fever, a skin rash emerges.
  • There is some minor bleeding (such a nose bleed, bleeding gums, or easy bruising)

Symptoms can be minor and easily confused with the flu or another viral infection. Younger children and persons who have never had the virus have a milder case than older children and adults. Serious issues, on the other hand, can arise. Dengue hemorrhagic fever is thought to be more common in people with compromised immune systems, as well as those who have had a second or subsequent dengue infection.

Effects after Dengue Fever

The symptoms of the first infection are usually mild. Once cured, the dengue virus’s lifelong immunity against serotypes is created. However, after the restoration Cross-immunity against the three serotypes is only partial and temporary. Dengue in severe Later infections with other serotypes of the virus is more likely to occur.
Acute dengue is a serious and potentially deadly complication against dengue fever. Initially, features include high fever, which can last up to 7 – 2 days, and C ° 41 – 40 degree range.
Dengue can cause yellowing of the face and other non-specific physical symptoms. Later In, warning signs such as severe abdominal pain, persistent vomiting, rapid breathing, fatigue, discomfort, and demonstrations of bleeding tendencies such as skin rashes, runny nose or gums, and possibly internal bleeding may occur. In severe cases, it results in circulatory failure, trauma, and death can do.

Cause of Dengue Fever

Cause of Dengue Fever

When a mosquito bites you, you get dengue fever. The virus is acquired by the mosquito by biting an infected person and then transmitted to another person. Dengue fever is not contagious and does not transfer from one person to another.
You have long-term immunity to the virus that infected you after you recover from dengue fever, but not to the other three varieties of dengue fever virus. This suggests that one of the other three virus kinds can infect you again in the future. If you catch dengue fever a second, third, or fourth time, your risk of developing severe dengue fever increases.


Preventing bites from infected mosquitoes is the greatest approach to avoid contracting the disease, especially if you live in or visit a tropical environment. This entails taking precautions and attempting to reduce mosquito populations.

  1. Even indoors, apply insect repellent.
  2. Long-sleeved shirts and long pants tucked into socks are recommended for outdoor use.
  3. air conditioning is available, use it when you’re indoors.
  4. Make sure the screens on your windows and doors are secure and without gaps. Use mosquito netting if your sleeping place isn’t screened or air-conditioned.
  5. Speak to your doctor if you have dengue symptoms.

Get rid of sites where mosquitoes can spawn to lower the mosquito population. Old tires, cans, and flower pots that gather rain are examples. Change the water in outdoor birdbaths and pet water bowls on a regular basis.
If someone in your household contracts dengue fever, be extra cautious about mosquito protection for yourself and other family members. Mosquito bites from an infected family member may spread the disease to others in the house.
Dr. Sher Shah Syed says that mosquito nets and sprays should be used because once the disease is transmitted, it can take two to three weeks for the virus to be eradicated from the body.
He said that after the rains if water accumulates around the houses or in the lawns, courtyards, etc., it is possible to prevent dengue by removing it immediately and spraying it there.

Nucleic acid amplification test:
 This test is performed for 7 or fewer days after the onset of symptoms and indicates the presence of the virus’s genetic material in the human serum.
Serological tests:
This is done 7 days after the onset of symptoms.  These tests are to detect the presence of antibodies against the virus in the blood.  IGA is formed 5 days after infection and IGM 2 to 4 weeks later.
After doing both tests, the doctor’s diagnosis undoubtedly becomes dengue.

Treatment of Dengue Fever

Treatment of Dengue Fever

There is no proper treatment for Dengue Fever

  1. Doctors say dengue patients should rest as much as possible
  2. Doctors are given plenty of water. This is important because it can reduce the number of hospital admissions.  In addition to water, you can drink fruit juices, ORS, etc.  However, the use of carbonated drinks should be avoided.
  3. Avoid the use of blood thinners such as aspirin, ibuprofen, and NCD.
  4. The patient should repeat the CBC and FBC tests. The number of white blood cells, platelets, and hematocrit in the blood is determined after the patient’s first blood test to determine how often they are repeated.

Repeat these tests to determine the treatment according to the levels initially set.  If the disease is in the early stages, the patient is asked to repeat the test on a daily basis.

Home Remedies for Dengue Virus

Diet plays an important role in eradicating any kind of infection, dengue fever is now spreading worldwide and more cases of dengue virus have been reported this year than last year.  The death toll has also risen.
The dengue virus can now be treated with home remedies that can get rid of the fever very quickly.
Papaya Leaves
Dengue causes a decrease in white blood cells in the body and the best food to make up for this deficiency is papaya leaves which make up for this deficiency very quickly which also get rid of the dengue virus.  For this you take 3 to 4 papaya leaves and wash them thoroughly, then crush those leaves and extract their juice and drink this juice 2 to 3 times a day, this juice is sick in the dengue virus.
Goat Milk
According to a study, goat’s milk is helpful for dengue patients. Goat’s milk contains a special type of protein that is not present in cow’s and buffalo’s milk.  It also helps prevent the spread of the virus. If a dengue patient is fed goat’s milk in the morning and evening, he can recover immediately.
Apple Juice
Apple juice makes up for the lack of blood in dengue patients. In addition, it also increases platelets. Apples contain antioxidants. The method used is:  Mix the juice and then mix and drink, the patient should take this juice 2 to 3 times a day.
Margosa(Neem) Leaves
Margosa leaves have the power to fight infections because they are antibacterial, Margosa leaves are very useful in the dengue virus, they make up for the lack of blood platelets and white blood cells.  Take some leaves and boil them in water and then filter the water. When the water cools down, add honey in it and drink it. This drink will be better for dengue patients.
Guava is rich in vitamins and minerals, it contains vitamin C and it also helps in boosting the immune system, which also increases the platelets of dengue patients. Dengue patients should take one to two cups of guava juice daily.  Drink or peel 2 to 3 guavas daily.

History of Dengue Fever

Dengue fever has surged 30-fold during the last five decades, making it a worldwide public health concern. Sri Lanka is one among 128 countries worldwide where DF is endemic. In Sri Lanka, dengue fever has reached epidemic proportions, with 186,101 cases reported in 2017. The Ministry of Health recently identified 12 regions on the island to be severely impacted. Over half of all cases have been reported from Sri Lanka’s Western province, notably from the Colombo and Gampaha districts, which have the highest and lowest dengue cases, respectively.


Insufficient attention, limited awareness and no systematized health education programmes have contributed negatively to the increase in dengue prevalence at schools, although increased vector receptivity has contributed positively. The purpose of this study was to investigate the current level of awareness of dengue infection among a selected sample of school children, as well as the efficacy of dengue awareness programmes in improving existing knowledge and dengue prevention practices.
Primary prevention is the most efficient method of preventing and controlling dengue fever. The study’s goals were to establish the study community’s degree of awareness and practice of dengue control, and (ii) investigate the factors affecting dengue control practice in the study region.
