Those which cause mosquito-borne diseases are called mosquito-borne viruses including Dengue, Yellow fever, Chikungunya, Zika viruses, and so on. Although people may not become sick after a bite from an infected mosquito, and some people have a mild, short-term illness or (rarely) severe or long-term illness, mosquito-borne viruses are considered the most important neurotropic flaviviruses, and severe cases can cause death.
According to the recent research paper published in the journal Cell on June 30, viruses like dengue and Zika can 'help' their host to better attract mosquitoes. The study shows that when humans and mice are infected with dengue or Zika viruses, they secrete a chemical that makes them smell delicious to mosquitoes. That kind of chemical compound of the smell with the highest response to experimental animals was called "acetophenone." The author and colleagues found that the increased levels of acetophenone were caused by an interplay between hosts' skin microbiota, flaviviruses (including dengue and Zika virus), and mosquitoes.
The World Health Organization (WHO) estimates that 390 million people are infected with the dengue virus each year and that almost half of the world's population lives in an area at risk of dengue fever. They suggested that dengue and Zika virus infections need to be differentiated from each other. Hence the NAAT testing (e. g. RT–PCR) methods are considered the gold standard for the diagnosis of dengue or Zika viruses.
Public health and clinical practitioners should be aware of locally prevalent pathogens, both to develop appropriate differential diagnoses and to identify circulating. Laboratory testing is critical for accurate diagnosis, clinical management, and epidemiologic surveillance, including detection, tracking, and control of outbreaks.
As a strategic partner of China CDC, Daan Gene has always been at the forefront of its efforts in the prevention and control of new and sudden outbreaks of infectious diseases. Daan Gene's Detection Kit for dengue and Zika Virus RNA (PCR-Fluorescence Probing) based on fluorescent RT-PCR technology, selected a highly conservative region as the target region to perform one-step RT-PCR amplification for the qualitative detection of virus RNA in specimens.

Some tropical viruses can change your scent to attract mosquitoes. This is how they find new hosts.
