Immunity-enhancing Foods to Prevent Dengue Fever

Dengue, probably the most popular(for all the wrong reasons!) mosquito-borne viral infection, is a common disease that affects thousands of Singaporeans every year. While the main focus is on prevention, and efforts are geared towards controlling mosquito-breeding to avoid being bitten, we must also pay attention to adopting an immunity-boosting diet to fight the deadly virus.

Singapore has been hit by a double whammy in recent times. We have been presented with quite a few cases of COVID-19, and an alarmingly high number of dengue cases as well. It has been a little over two months since the start of the new year and Singapore has already witnessed 3640 dengue cases as of 7 March, 2020. In addition to the steps we should be taking to prevent the breeding of mosquitoes in our own homes, we can also look into strengthening our immunity by consuming a healthy diet of food for dengue prevention.

List of foods to prevent the disease and boost your immunity 

Dengue is transmitted through the bite of Aedes aegypti and Aedes albopictus mosquitoes, and despite concentrated efforts by authorities such as the National Environment Agency (NEA), Inter-Agency Dengue Task Force (IADTF) and Town Councils island-wide, the potentially fatal viral infection continues its rapid spread.

NEA’s main prevention strategy includes active monitoring and the breaking of breeding cycles. They have also requested the public to be vigilant and check for mosquito-breeding corners in our homes, and to use insect repellents to avoid being bitten.

However, there’s more we can do to prevent contracting the disease. We can certainly improve our immunity against the disease by incorporating several effective food for dengue prevention into our diets. 

Here is a list of immunity-boosting food for dengue that can help you fight the virus:
