With winter approaching and the weather changing, the number of people falling sick with viral fever is on the rise. Covid-19 cases, though fewer than before, get reported and dengue cases in particular have spiked. Dr Tarun Sahani, Senior Consultant, Internal Medicine, Apollo Hospitals, Delhi, spoke to us about the overlapping symptoms between dengue and Covid-19, its causes, prevention, and how to take care of oneself if you have a fever.
Dengue fever: Causes and symptoms
Dengue fever is a mosquito-borne illness that occurs in tropical and subtropical areas of the world like India. Even if you have mild dengue fever, that can mean high temperature and flu-like symptoms. The severe form of dengue fever can be fatal. Also called dengue haemorrhagic fever, it can cause serious bleeding, a sudden drop in blood pressure (shock), and even death. When dengue starts showing symptoms, it may be mistaken for other illnesses — such as the flu — and usually begin four to 10 days after people is bitten by an infected mosquito. Severe bleeding and a sudden drop in blood pressure as well as death can occur due to a severe form of dengue fever. Dengue fever causes a high fever — 104 F (40 C) — and any of the following signs and symptoms:
- Headache
- Muscle, bone or joint pain
- Nausea
- Vomiting
- Pain behind the eyes
- Swollen glands
- Rash

Some people may have no symptoms at all, but can still spread it (asymptomatic transmission). Some people may experience worsened symptoms, such as worsened shortness of breath and pneumonia, about a week after symptoms start. Signs i.e. troubled breathing, persistent pain, or pressure in the chest are signs of severe Covid – 19.

Covid-19 Vs Dengue: Differentiate common symptoms
A number of cities in India have shown a spike in dengue cases. Sometimes, dengue and Covid-19 show similar symptoms and some overlapping symptoms include fever, chills, headache, and body ache. In Covid-19, especially currently, the fever is often a low or moderate one. Dengue, meanwhile, often shows high fever, which continues to rise. The fever is constant whereas in Covid, the fever might come and go.
Precautions for Dengue and Covid-19
Dengue viruses are spread to people through the bites of infected mosquitoes, mainly Aedes aegypti mosquitoes. The virus that causes Covid-19 is thought to spread mainly through respiratory droplets produced when an infected person coughs, sneezes, or talks.
Precautions against Dengue
1) Dengue mosquitoes breed in stagnant water. So clean up your surroundings and get rid of objects like tires, and plastic covers. Keep flower pots, pets’ water bowls, etc clean.
2) Close doors and windows properly.
3) Use mosquito repellents.
4) Wear protective clothing. Wear long-sleeved tops, shirts, trousers, and put on socks.
5) You may not love it but mosquito nets are handy to protect yourself from dengue. Use one while sleeping.
6) Clean, airy homes which are well-lit are less frequented by mosquitoes as compared to dark and damp places.
