In recent years, the spread of dengue fever due to lack of hygiene and climatic conditions has been rampant in developing countries. Urbanization and population explosion have made dengue more endemic and the number of cases reported keeps increasing every year. As dengue burden rises in the country, the likelihood of more people becoming severely ill grows. Read on and know more about the reasons for dengue and the simple precautionary methods to prevent it. 

What causes dengue?

Four types of dengue viruses are responsible for causing this hemorrhagic disease in man. Mosquitoes that thrive in and near human lodgings carry the viruses to people through their pricking bites. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. The infected insect then bites another person and passes the pathogen to the person’s bloodstream.

When you've recovered from dengue fever, your body develops immunity to the type of virus that struck you. It doesn’t mean that you are safe from the other three dengue pathogens. The risk of developing severe dengue fever, also known as dengue hemorrhagic fever, actually increases if you're infected a second, third or fourth time.

Know your symptoms

In mild cases of dengue, people may not exhibit signs of dengue fever. But symptoms do occur within four to seven days after the mosquito bite. It causes a sudden drop in platelet count. When affected by dengue, the temperature may rise to 104F and the patient is likely to suffer from headaches, swollen joints, nausea and muscle pain. Usually, the fever subsides in a week. In some cases, the symptoms can worsen and it can be life-threatening.

Blood vessels can get damaged and the victim suffers from severe abdominal pain, Persistent vomiting, bleeding from gums or nose, blood in urine, stools or vomit. Rush to an emergency room when you suspect symptoms of dengue.

What can be done?

Vaccines against dengue have not been successful as any person who has not been affected by dengue can develop a severe infection after few years of vaccination. 

A few simple tips can help you stay away from dengue- infected mosquitoes, especially when living in tropical areas. They are:

  1. Remove stagnant water from construction sites, water pots, sinks etc to prevent the breeding of mosquitoes. 
  2. Stop water contamination by closing water reservoirs and tanks 
  3. Wearing full sleeved clothes can save from mosquito bites
  4. Use of Mosquito repellents, nets and traps are effective in preventing mosquito menace at home

The Indian government has taken measures to curb the epidemic of dengue in urban and developing rural areas. Campaigns are conducted to educate people about the do’s and don’ts of dengue fever.

It is much easier to prevent a problem from happening than to solve the problem after it has already happened.

Keeping ourselves informed about the safety tips can help us spare a lot of stress, time and money and sometimes can also save our lives.
