Dengue fever is a disease caused by mosquito bites. It affects millions of people every year with tropical countries being the most affected. Mosquitos carrying the dengue virus spreads the disease, often without any complications. However, there are rare cases when it can be deadly. The fever is often ‘flu-like, but it can develop into a hemorrhagic fever.
When it becomes a dengue hemorrhagic fever, the disease becomes fatal, especially for an immunocompromised person. Fortunately, a few vaccines against dengue fever are already under development. Some have even been approved recently. With these vaccines, it is possible to protect the people living in areas affected by the virus as well as the travelers who venture in those regions.
This illness is widespread in more than 100 countries with around 100 million clinical cases occurring every year. The severe infection mostly affects children and infants that live in the tropics and subtropics. In these areas, outbreaks are frequent, which often happens in a seasonal pattern. In Southern Europe, there have been outbreaks due to imported infection, according to some reports.
It takes about 4 to 10 days for the symptoms of dengue fever to develop after an individual is affected by the virus. These symptoms become worse in the first week, which makes early detection critical. The symptoms of dengue fever are:
Once the initial phase passes, the symptoms go away as well. However, you may still feel a general unwellness or fatigue that lingers for a few weeks. This lingering feeling will usually go away after a while after proper treatment is administered. Early detection can increase the chance of recovery as well as getting vaccinated, especially if you will be traveling to a disease risk country.
Dengue fever is due to a virus, which is contracted through the bites of infected mosquitos. The illness is most common in countries such as Southeast Asia, Africa, the Caribbean, Australia, India, Central America, South America, and the Pacific Islands. Dengue fever vaccines are not widely available, which is why prevention is the best way you can protect yourself against the bites.
There are now vaccines for the dengue fever available, but as mentioned before, they are not available worldwide. These vaccines help to prevent the virus from spreading, either through mosquitoes or by any other means. There are also several other dengue vaccines going through development. In Brazil and Mexico, there is one vaccine already approved.
If you are in an area with a high chance of contracting dengue fever, getting the vaccination is crucial to protect yourself. Moreover, if you recently went to a region where the disease is present, and you are experiencing the symptoms mentioned above, you are recommended to see the doctor the soonest you can. Our clinic is also here to help to provide you with dengue fever vaccine and other health advice.
