Comprehensive Dengue Guide
Although mosquitoes causing dengue (Aedes Aegypti mosquito) are known to bite primarily during the day, they can bite during the night as well. You can easily recognise these mosquitoes based on the characteristic stripes on their body.
2. Where do these mosquitoes breed?
These mosquitoes can breed in clean water (unlike those causing malaria). So right from water logging sites, unused tires, water tanks to trays of potted plants, they can breed anywhere and everywhere in your locality. Also, the warm humid climate and dark and warm places in your house are known to be ideal breeding grounds for these mosquitoes.
3. How does dengue spread?
Dengue, a viral disease, spreads when an Aedes Aegypti mosquito infected with the dengue virus bites a healthy individual. This causes the virus to enter the bloodstream and multiply, leading to dengue fever.
4. Who is at risk of dengue?
You might be at a high risk of suffering from dengue if you live in a dengue-prone area or have already suffered from dengue. Also, people who have low immunity, like kids and old people and those suffering from lifestyle conditions like heart disease or diabetes are more prone.
5. Can I get dengue from a person suffering from the disease?
Dengue is not a contagious disease; i.e. it doesn’t spread from one person to other through physical contact. It only spreads when a mosquito infected with the dengue virus bites a person.
6. When do the symptoms of dengue start to appear?
Once the virus infected mosquito bites, it usually takes around 4 – 10 days for the symptoms to appear.
7. What are the symptoms of dengue?
Dengue is characterised by high fever (103°F-104°F) followed by severe headache, pain behind the eyes, muscle and joint pain and skin rash. In some cases, fatigue, diarrhoea and vomiting are also reported.
8. How to differentiate between viral fever and dengue fever?
In case of viral fever, you experience high fever coupled with chills and (in some cases headache). However, people suffering from dengue report severe headache, pain behind the eyes, weakness, skin rash and/or severe joint pain along with high fever.
9. Can dengue be diagnosed at home (without a blood test)?
You can diagnose dengue at home based on the symptoms but to confirm it, you need a blood test. Hence, you can’t confirm the viral disease unless it is backed by a blood test.
10. How to get tested for dengue?
Dengue can be diagnosed with the help of a blood test – complete blood count (CBC) and an antigen/antibody test for dengue. The CBC test tells you about platelet and haemoglobin count whereas NS1 antigen and antibody test for IgM and IgG confirms dengue infection.
11. Does low platelet count always indicate dengue?
Low platelet count is one of the key symptoms of dengue but it doesn’t always indicate dengue. It has to be supplemented with a dengue antigen or antibody test to confirm the disease. Clinically known as thrombocytopenia, low platelet count can occur in case of viral fever as well.
12. Is it necessary to get tested for dengue only when you have high fever?
Although it is good to get tested for dengue when you have a high fever, it is not always necessary to get it done when you have fever (unlike malaria). The reports do not indicate false negative results when done when you don’t have fever.
13. Can a person suffer from dengue and not appear weak?
Yes, it is possible that a person might suffer from dengue but do not show any signs or symptoms of the same. Hence, it is not a bad idea to get tested for dengue if your doctor recommends the same.
14. Do I need to undergo antibody test for dengue even if my NS1 antigen test is negative?
The NS1 Antigen test might show negative results in the initial stages of the disease and thus, needs to be repeated to get confirmatory results. Whereas, antibody test (IgG and IgM) can be recommended during the later course of the disease (after 5 days of suffering from fever) and gives accurate results in most cases.
15. How many days after getting tested for dengue, will I get the blood reports?
You can get CBC and NS1 Antigen test within 4 – 5 hours after your blood is done, whereas antibody test for dengue can be obtained after 2 – 3 days.
16. If a person has low platelet count and high haemoglobin count, does he/she need to worry?
Yes, if a person has low platelet count coupled with high haemoglobin levels, he/she should be admitted. This is because, people suffering from dengue limit their intake of water than in turn causes the blood tissue to dry leading to high PCV (packed cell volume) and high haemoglobin. Here’s everything you need to know about high haemoglobin count in dengue patients indicate medical emergency.
17. Can dengue be treated at home?
There is no need to admit a person unless he/she appears weak, has very low platelet count (or platelet count drops at a very fast pace) coupled with high haemoglobin levels. However, make sure to consult the doctor from time to time and undergo a blood test daily to keep a tab on platelet count. And most important thing, people suffering from dengue should stay hydrated, take sufficient rest and consult a doctor from time to time without fail.
18. How is dengue treated?
There is no specific treatment for dengue. The treatment options are aimed at improving the platelet count and treating the infection. The main aim of the treatment is to maintain the fluid balance in the body through IV fluids.
19. I suffered from dengue earlier; can I get it again?
Yes, you can get dengue the next time even if you were infected before. There are four different strains of dengue virus. If you have been infected with one strain earlier, then the chances of the infection by another one is also high.
20. What will happen if I suffer from dengue the second time?
If the infection is from the same strain of the dengue virus that caused an infection earlier, your body can fight the infection as your body now has antibodies against the virus. However, if the infection is due to another strain of the virus, there is a high risk of severe health complications the second time you are infected.
21. When should a person get admitted or hospitalised?
If a person has fever for more than 3 days, has a rapid drop in the blood platelet count since a day or two and shows a high haemoglobin level, it means that the person needs urgent medical attention. Also, if the person becomes lethargic or suffers from a severe body pain, it is wise to consult a doctor before admitting him/her to a hospital.
22. How long should a person suffering from dengue take medications?
It is important to complete the course of the medications as advised by your doctor. If you stop taking medications midway, there are high chances that the viral infection might revert back.
23. Does low platelet count mean I need to undergo platelet transfusion?
A low platelet count does not always indicate platelet transfusion. However, if your blood platelet count is lesser than 40,000, the person is not responding well to the treatment or there is bleeding, then doctors might go for platelet transfusion.
24. What are the possible complications of dengue?
If left untreated or not treated on time, dengue might lead to severe abdominal pain, myalgia, nausea, severe headache, fluid accumulation in the chest and liver and haemorrhages.
25. Can a person die from dengue?
A person suffering from dengue fever is less likely to die but he/she can develop dengue haemorrhagic fever (DHF) or dengue shock syndrome (DSS). If both these cases are not treated on time, there are high chances that the person might die.
26. Is there any vaccine available to prevent dengue?
As of now, there is no vaccine available for prevention against dengue. However, clinical trials are still going on in this regard. If reports are to be believed, Brazil has said that the dengue vaccine will be available by 2018.
27. Are papaya leaves effective against dengue?
Dr Sanath Hettige, a general physician in Sri Lanka, in his paper published in the Sri Lankan Journal of Family Physicians in 2008 stated that papaya leaves contain chymopapin and papain, enzymes, which not only normalise platelet count but also repair the damage done to the liver by dengue.
28. Are there any other ayurvedic remedies to treat dengue?
There are many rumours making rounds in the market that eating exotic fruits like kiwi and dragon fruit improve your platelet count. Also, consuming juice made from aloe vera, pomegranate or giloy leaves and goat milk improves your immunity and thus, helps in treating dengue doesn’t have any substantial evidence.
29. Is there any special diet for people suffering from dengue?
People suffering from dengue should increase their intake of liquids, either in form of plain water, coconut water or fruit juices. Avoid spicy and oily foods till you recover completely. Include foods rich in vitamin C and proteins in your diet
30. After how many days, can a person suffering from dengue get back to their routine life?
In most cases, people might experience weakness for some days even after the fever subsides. So depending upon a person’s energy levels, one can get back to work.
31. How to prevent dengue?
The key to prevent dengue is to keep your house mosquito free. Cover water containers, use mosquito repellents creams and nets and keep the dustbins and garbage cans covered. Here are innovative ways to keep your home mosquito free.
32. Are there any natural remedies to keep your home mosquito-free?
Yes, there are few natural remedies you can try to keep your house mosquito-free. This includes using neem oil, camphor, tulsi, garlic, lemon and eucalyptus and citronella. Here’s how you can use them to prevent mosquitoes from entering your home. more
