Dengue Virus Nucleic Acid Positive is Not Contagious
Dengue is a mosquito-borne viral infection that can cause a wide range of symptoms, from mild fever to severe, life-threatening illness. The virus is transmitted to humans through the bite of an infected mosquito.
Dengue virus nucleic acid (RNA) is the genetic material of the virus. It is found in the blood of infected people and can be detected using a variety of laboratory tests. However, the presence of dengue virus RNA in the blood does not necessarily mean that the person is contagious.
What does it mean to be contagious?
Contagiousness refers to the ability of a person to transmit an infection to another person. In the case of dengue, a person is considered to be contagious if they are able to transmit the virus to a mosquito that bites them.
How is dengue transmitted?
Dengue is transmitted through the bite of an infected mosquito. When a mosquito bites an infected person, it ingests the virus along with the blood. The virus then multiplies inside the mosquito and is eventually transmitted to another person when the mosquito bites them.
Can a person with dengue virus RNA in their blood transmit the virus to others?
No. A person with dengue virus RNA in their blood is not necessarily contagious. The virus must first replicate inside the mosquito before it can be transmitted to another person. This process takes several days, and during this time the person is not contagious.
When is a person with dengue contagious?
A person with dengue is contagious from the time they develop symptoms until about 5 days after the onset of symptoms. During this time, the virus is present in the blood at high levels and is able to be transmitted to mosquitoes.
How can I protect myself from dengue?
There is no specific treatment for dengue, but there are a number of things you can do to protect yourself from the virus. These include:
Using mosquito repellent
Wearing long sleeves and pants when you are in areas where there are mosquitoes
Staying in air-conditioned rooms
Using mosquito nets
Getting rid of standing water around your home
What should I do if I think I have dengue?
If you think you may have dengue, it is important to see a doctor right away. Early diagnosis and treatment can help to prevent serious complications.
