What is the difference between dengue IgG and IgM?
The IgM become detectable on Day 3 to 5 of illness in case of primary dengue infection and persist for 2 to 3 months, whereas IgG appear by the fourteenth day and persist for life. Secondary infection shows that IgG rises within 1 to 2 days after onset of symptoms, simultaneously with IgM antibodies.
What is anti dengue IgG positive means?
Positive IgM and IgG tests for dengue antibodies detected in an initial blood sample mean that it is likely that the person became infected with dengue virus within recent weeks.
What are the 4 types of dengue virus?
Dengue is caused by a virus of the Flaviviridae family and there are four distinct, but closely related, serotypes of the virus that cause dengue (DENV-1, DENV-2, DENV-3 and DENV-4). Recovery from infection is believed to provide lifelong immunity against that serotype.
What are the stages of dengue?
There are 3 phases of the disease.
- Stage I:Acute fever stage.(~Day 1-5).
- Stage II:Critical stage.(~Day 5-7), at this stage when the body temperature drops, normally within 24 hours, the plasma (Fluid part of blood component) leaks and the blood pressure will drop.
- Stage III: Recovery phase.
- DF at a glance.
What if IgM is positive and IgG is negative?
The positive IgM plus negative IgG (IgM+ plus IgG-) results showed that 38% of those patients had a recent primary dengue infection, while the positive IgG plus either positive or negative IgM (IgG+ plus IgM+/-) results indicated that 62% had dengue for at least a second time (recent secondary infections).
How long is dengue IgG positive?
In secondary dengue infections, IgG titers rise to extremely high levels (much higher than in primary infections) from the day 7 of fever to the next two weeks (9, 11). Anti-Dengue IgG antibodies persist for a long time even up to years (3, 12).
How long can dengue last?
Symptoms of dengue typically last 2–7 days. Most people will recover after about a week.
How many times can you get dengue?
Dengue is caused by one of any of four related viruses: Dengue virus 1, 2, 3, and 4. For this reason, a person can be infected with a dengue virus as many as four times in his or her lifetime.
Is hospitalization required for dengue?
Doctors say most dengue cases can be managed in the outpatient departments of hospitals and only the most severe cases need hospitalisation. The World Health Organisation or WHO has released an advisory on the symptoms in patients that should lead to hospitalisation.
What does IgG IgM positive mean?
A positive IgM test indicates that you may have been infected or that you have recently been vaccinated and your immune system has started responding to the vaccination and that your immune system has started responding to the virus.
