POF Hospital 2019
• Total no of suspected cases in POF Hospital: 204
• Dengue Serology : 1 +ve
• Dengue NS1 Antigen : 21 +ve
• Death : 1
Etiology
• Dengue Virus: Enveloped RNA virus
• Serotypes:DENV-1,DENV-2,DENV-3,DENV-4
• Homotypic immunity: Life long
• Heterotypic immunity: Short period
• Each serotype provide specific life long immunity and short term cross
immunity
Transmission
• Vector: Infected Female Aedes aegypti
• Carriers: Infected Humans
• Cycle: Mosquito-Human-Mosquito
• Incubation Period in humans: 4-10 days
• Viraemia period: 3-5 days,requires sufficient viral titers to infect
mosquitoes
• Incubation Period in mosquitoes: 8-12 days, then remain infected till
mosquitoes life
Transmission
• Vector: Aedes aegypti
• Pregnancy: A pregnant woman already infected with dengue can pass
the virus to her fetus during pregnancy or around the time of birth
• Breast Feeding: To date, there has been one documented report of
dengue spread through breast milk.
• Rare Routes: Rarely, dengue can be spread through blood transfusion,
organ transplant, or through a needle stick injury.

Facts
• These mosquitoes typically lay eggs near standing water in containers
that hold water, like buckets, bowls, animal dishes, flower pots, and
vases.
• These mosquitoes prefer to bite people, and live both indoors and
outdoors near people.
• Mosquitoes that spread dengue, chikungunya, and Zika bite during
the day and night.
• Mosquitoes become infected when they bite a person infected with
the virus. Infected mosquitoes can then spread the virus to other
people through bites.
Dengue Fever Classification (1997-WHO)
• Dengue Fever DF
• Dengue Haemorrhagic Fever DHF (DHF GRADE 1,2)
• Dengue Shock Syndrome DSS (DHF GRADE 3,4)
• Source : https://www.ncbi.nlm.nih.gov/pubmed/16903887
Dengue Fever Classification (2009-WHO)
Dengue Case Definitions 2015 NNDSS
• Suspected
• A clinically compatible case of dengue-like illness, dengue, or severe
dengue with an epidemiologic linkage.
• Probable
• A clinically compatible case of dengue-like illness, dengue, or severe
dengue with laboratory results indicative of probable infection.
• Confirmed
• A clinically compatible case of dengue-like illness, dengue, or severe
dengue with confirmatory laboratory results.
Clinical Features
•Warning Signs
•Abdominal pain or tenderness
•Persistent vomiting
•Extravascular fluid accumulation (e.g., pleural or
pericardial effusion, ascites)
•Mucosal bleeding at any site
•Liver enlargement >2 centimeters
•Increasing hematocrit concurrent with rapid decrease
in platelet count

Molecular test
• Nucleic Acid Amplification Test (NAAT)
• For symptomatic patients during the first 1-7 days of illness, any
serum sample should be tested with a NAAT and for IgM antibody
since both tests can be performed in serum. Performing both tests
can detect more cases than performing just one test.
• After day 7 of illness, few cases can be detected by NAAT.
Interpretation of results
• A positive NAAT result confirms dengue virus infection.
• A negative NAAT result does not rule out infection. People with NAAT
negative results should be tested for the presence of IgM antibodies
against dengue virus to determine possible recent dengue exposure.
• If both the NAAT and IgM antibody results from the acute phase of
illness are negative, a convalescent serum should be obtained for IgM
antibody testing.
• IgM laboratory unconfirmed case: If a patient with suspected dengue
virus infection submits an acute phase specimen that is negative (e.g.,
by NAAT and/or IgM antibody), and the patient does not submit a
convalescent specimen, the patient’s diagnosis is unconfirmed.
Dengue Virus Antigen Detection NS1
• NS1 is detectable during the acute phase of dengue virus infections.
NS1 tests can be as sensitive as molecular tests during the first 0-7
days of symptoms. After day 7, NS1 tests are not recommended.
• A positive NS1 test result confirms dengue virus infection without
providing serotype information.
• A negative NS1 test result does not rule out infection. People with
negative NS1 results should be tested for the presence of dengue IgM
antibodies to determine possible recent dengue exposure.
Serologic Tests
• Dengue virus-specific IgM and neutralizing antibodies typically
develop toward the end of the first week of illness. IgM levels are
variable, but generally are positive starting 4-5 days after onset of
symptoms and continuing for approximately 12 weeks post symptom
onset, but may persist longer.
Interpretation of results
• Positive IgM: Patients with a positive IgM test result are classified as
presumptive, recent dengue virus infections.
• Negative IgM:
• Patients with negative IgM results before day 8 of illness and absent or negative NAAT or NS1
results are considered unconfirmed cases. For these cases, a second sample should be
obtained after day 7 of symptoms for additional serologic testing.
• Patients with negative IgM results after 7 days of symptoms, and absent or negative NAAT or
NS1 (dengue virus antigen detection) are classified as negative for recent infection.
• Patients with a change from negative to positive IgM results in paired samples (first sample
collected during the first 7 days of illness, and second sample collected after symptoms
subside) are classified as current dengue infections.
• Due to cross-reaction with other flaviviruses and possible nonspecific reactivity,
results may be difficult to interpret. Consequently, presumed positive,
indeterminate, and equivocal, IgM antibody test results may be forwarded for
confirmation by plaque reduction neutralization testing (PRNT)

  • 10. POF Hospital 2019 • Total no of suspected cases in POF Hospital: 204 • Dengue Serology : 1 +ve • Dengue NS1 Antigen : 21 +ve • Death : 1
  • 11. Etiology • Dengue Virus: Enveloped RNA virus • Serotypes:DENV-1,DENV-2,DENV-3,DENV-4 • Homotypic immunity: Life long • Heterotypic immunity: Short period • Each serotype provide specific life long immunity and short term cross immunity
  • 12. Transmission • Vector: Infected Female Aedes aegypti • Carriers: Infected Humans • Cycle: Mosquito-Human-Mosquito • Incubation Period in humans: 4-10 days • Viraemia period: 3-5 days,requires sufficient viral titers to infect mosquitoes • Incubation Period in mosquitoes: 8-12 days, then remain infected till mosquitoes life
  • 13. Transmission • Vector: Aedes aegypti • Pregnancy: A pregnant woman already infected with dengue can pass the virus to her fetus during pregnancy or around the time of birth • Breast Feeding: To date, there has been one documented report of dengue spread through breast milk. • Rare Routes: Rarely, dengue can be spread through blood transfusion, organ transplant, or through a needle stick injury. • Source: https://www.cdc.gov/dengue/transmission/index.html • https://academic.oup.com/cid/article/57/3/415/460422#89056229
  • 14. Facts • These mosquitoes typically lay eggs near standing water in containers that hold water, like buckets, bowls, animal dishes, flower pots, and vases. • These mosquitoes prefer to bite people, and live both indoors and outdoors near people. • Mosquitoes that spread dengue, chikungunya, and Zika bite during the day and night. • Mosquitoes become infected when they bite a person infected with the virus. Infected mosquitoes can then spread the virus to other people through bites.
  • 15. Dengue Fever Classification (1997-WHO) • Dengue Fever DF • Dengue Haemorrhagic Fever DHF (DHF GRADE 1,2) • Dengue Shock Syndrome DSS (DHF GRADE 3,4) • Source : https://www.ncbi.nlm.nih.gov/pubmed/16903887
  • 17. Dengue Case Definitions 2015 NNDSS • Suspected • A clinically compatible case of dengue-like illness, dengue, or severe dengue with an epidemiologic linkage. • Probable • A clinically compatible case of dengue-like illness, dengue, or severe dengue with laboratory results indicative of probable infection. • Confirmed • A clinically compatible case of dengue-like illness, dengue, or severe dengue with confirmatory laboratory results.
  • 18. Clinical Features •Warning Signs •Abdominal pain or tenderness •Persistent vomiting •Extravascular fluid accumulation (e.g., pleural or pericardial effusion, ascites) •Mucosal bleeding at any site •Liver enlargement >2 centimeters •Increasing hematocrit concurrent with rapid decrease in platelet count

  • 31. Molecular test • Nucleic Acid Amplification Test (NAAT) • For symptomatic patients during the first 1-7 days of illness, any serum sample should be tested with a NAAT and for IgM antibody since both tests can be performed in serum. Performing both tests can detect more cases than performing just one test. • After day 7 of illness, few cases can be detected by NAAT.
  • 32. Interpretation of results • A positive NAAT result confirms dengue virus infection. • A negative NAAT result does not rule out infection. People with NAAT negative results should be tested for the presence of IgM antibodies against dengue virus to determine possible recent dengue exposure. • If both the NAAT and IgM antibody results from the acute phase of illness are negative, a convalescent serum should be obtained for IgM antibody testing. • IgM laboratory unconfirmed case: If a patient with suspected dengue virus infection submits an acute phase specimen that is negative (e.g., by NAAT and/or IgM antibody), and the patient does not submit a convalescent specimen, the patient’s diagnosis is unconfirmed.
  • 33. Dengue Virus Antigen Detection NS1 • NS1 is detectable during the acute phase of dengue virus infections. NS1 tests can be as sensitive as molecular tests during the first 0-7 days of symptoms. After day 7, NS1 tests are not recommended. • A positive NS1 test result confirms dengue virus infection without providing serotype information. • A negative NS1 test result does not rule out infection. People with negative NS1 results should be tested for the presence of dengue IgM antibodies to determine possible recent dengue exposure.
  • 34. Serologic Tests • Dengue virus-specific IgM and neutralizing antibodies typically develop toward the end of the first week of illness. IgM levels are variable, but generally are positive starting 4-5 days after onset of symptoms and continuing for approximately 12 weeks post symptom onset, but may persist longer.
  • 35. Interpretation of results • Positive IgM: Patients with a positive IgM test result are classified as presumptive, recent dengue virus infections. • Negative IgM: • Patients with negative IgM results before day 8 of illness and absent or negative NAAT or NS1 results are considered unconfirmed cases. For these cases, a second sample should be obtained after day 7 of symptoms for additional serologic testing. • Patients with negative IgM results after 7 days of symptoms, and absent or negative NAAT or NS1 (dengue virus antigen detection) are classified as negative for recent infection. • Patients with a change from negative to positive IgM results in paired samples (first sample collected during the first 7 days of illness, and second sample collected after symptoms subside) are classified as current dengue infections. • Due to cross-reaction with other flaviviruses and possible nonspecific reactivity, results may be difficult to interpret. Consequently, presumed positive, indeterminate, and equivocal, IgM antibody test results may be forwarded for confirmation by plaque reduction neutralization testing (PRNT)
  • 38. Case Management • Group A- Dengue with out Warning Signs- Outdoor treatment • Group B-Dengue with Warning Signs/Co Morbids- Indoor treatment • Group C-Severe Dengue- Indoor treatment
  • 39. Group A Management • Can be sent home • Tolerate oral fluids • Absence of warning signs • Oral rehydration therapy • Adequate urine out put, once every 6 hour • Oral Paracetamol every 6 hours • Avoid Aspirin,NSAIDS. • Advise when to visit ED

  • 51. Dengue Vaccine • Age: 9-45 Years • Confirmed Dengue Case • Dosage: 3 doses.6 months apart. • The vaccine manufacturer, Sanofi Pasteur, announced in 2017 that people who receive the vaccine and have not been previously infected with a dengue virus may be at risk of developing severe dengue if they get dengue after being vaccinated.
