Quercetin is a flavonoid that has demonstrated anti-viral properties against a wide range of viral infections, including the flu. In the current cell study quercetin was shown to reduce viral replication of the dengue fever virus by 67%. Quercetin does not appear to have direct anti-viral properties or to prevent viral entry into cells. Rather, it appears to work on the gene signaling relating to energy production in virally infected cells, significantly inhibiting the ability of the virus to replicate. This results in a weaker infection, thus giving one’s immune system more time to get on top of the problem. This mode of operation is likely a general anti-viral principle of quercetin, making it a good part of an immune support program to help combat any viral infection.
Dengue is a major mosquito-borne disease currently with no effective antiviral or vaccine available. It is uncommon in the United States, although it is endemic in Puerto Rico. It occurs in parts of Mexico, Central America, the Caribbean, and other tropical climates around the world. If you are considering traveling to a tropical climate you can check out this CDC map to see outbreaks of dengue in various places around the globe.
If you run a fever during or following a trip to one of these areas you may want to try some quercetin along with other natural immune support, as well as getting appropriate medical care.
