Brief Answer:
Can take up to a week sometimes, also, check for malaria

Detailed Answer:
Hello,
Thank you for your query.
I'm Dr Shuba Hariprasad and will be answering be answering your query today.

Would you clarify a few things for me, please?
*how long has she had the fever for?
*any rashes over the body?
*does she have any other medical issues or take any medications?
*does she have any urinary symptoms like burning urine or pain?
*did they do a test for dengue? How much was it?
*what are her latest blood tests like?

The fever of dengue can last for 3-5 days, sometimes even more.
Have they checked for Malaria and urinary tract infection?

I'd recommend :
-serial blood counts every day to check for severe low counts.
-avoid too much fluid rehydration. Fluid restoration must be calculated and administered adequately. Too much fluid can dilute the blood and show falsely low blood counts. Talk to her treating doctor about this.
-peripheral smear, QBCMP, Blood culture to check for Malaria and other Infections.

In certain cases prophylactic Malaria treatment my be warranted if fever persists without any new symptoms.
I know it's a difficult situation and frustrating that even being in the hospital is not helping much.
However, viral Infection like dengue will take its course.

There is only symptomatic treatment and complications need to be caught early and treated
accordingly.

If platelets reduce less than 20,000 or she develops any bleeding issues, she may need a transfusion. The counts will come back up once the Infection has run its course.

It is better to be in the hospital setting only so that any complications can be immediately treated.
Please make sure it is a tertiary care hospital with required facilities (blood bank, round the clock intensive care doctors available).

Avoid any relatives with cold, cough or those children who are recently vaccinated, from coming near her till gets better.

Hope this helps. Please let me know if I can assist you further.
Wish you both good health,

Regards,
Dr Shuba Hariprasad

Brief Answer:
Please check for Malaria right away

Detailed Answer:
Hello,
Thank you for the follow up and clarifications.

-please ask them to check for Malaria right away. Blood tests - peripheral smear (thick & thin smear),
QbcMp, blood culture, dengue Igm, liver and kidney function tests.
Ns1 antigen test is good for early detection but not specific for dengue.

-get an OBGYN opinion to check the status of pregnancy and to make sure bleeding is not from the uterus.

You and your wife must be anxious but please stay calm and focused. Make sure you get proper assistance and guidance /responses from the doctors.
Pregnancy makes the body more vulnerable to infection & can take time to recover. However, diagnosis needs to check for Malaria or other possible infections as fever still persists.
