The virus initially targets keratinocytes (skin cells) and Langerhans cells (specialized immune cells).

The invasion begins at the cellular level. When an infected mosquito bites a human, the virus enters the skin through the insect's saliva.

New research suggests dengue uses unique replication strategies that allow it to hijack host machinery more effectively than many other viruses. Geographic Expansion: Crossing Borders

The Dengi Invasion is accelerating due to three human factors:

We are the vectors. An infected traveler can fly from Bangkok to Paris in 12 hours, landing in a new territory where local mosquitoes bite them, pick up the virus, and begin a new front of the invasion.
