This document describes a case of dengue fever in a 36-year-old female patient who presented with high fever, body aches, headaches and joint pains for 4 days. Her lab tests showed low platelet count and hematocrit increase. She was diagnosed with dengue fever with warning signs and died within 24 hours of admission. It then provides details on the epidemiology, transmission, clinical presentation and management of dengue fever, noting it is a mosquito-borne illness caused by the dengue virus with nearly 400 million cases annually worldwide.
An acute fibrile illness syndrome caused by arboviruses that characterized by biphasic fever, myalgia, arthralgia, leukopenia, rash & lymphadenopathy.A.k.a dengue / breakbone fever
Only 1/3 of DHF patient develop shock and circulatory failure ( outpatient Tx is enough , bring back when there are alarming signs) .Early plasma, fluid & electrolyte replacement proved to have favourable outcome( maintain circulation). In DHF/DSS case, great care taken to reduce invasive procedures while managing shock

My Presentation in College.
Hope its useful for you rather than sleeping in my desktop.
Sorry if there is any mistakes.
The presentation is about Dengue fever. First starting with the basic information like Introduction , Epidemiology ,Vector , Viral Morphology ,Mode of Transmission. Then little bit on Pathogenesis and Immune Response. Extra focus given to the Clinical Manifestations, symptoms and Lab Diagnosis with few simplified case studies. Control and prevention and treatment also included.
CRISPR-Cas9, a revolutionary gene-editing tool, holds immense potential to reshape medicine, agriculture, and our understanding of life. But like any powerful tool, it comes with ethical considerations.
Unveiling CRISPR: This naturally occurring bacterial defense system (crRNA & Cas9 protein) fights viruses. Scientists repurposed it for precise gene editing (correction, deletion, insertion) by targeting specific DNA sequences.
The Promise: CRISPR offers exciting possibilities:
Gene Therapy: Correcting genetic diseases like cystic fibrosis.
Agriculture: Engineering crops resistant to pests and harsh environments.
Research: Studying gene function to unlock new knowledge.
The Peril: Ethical concerns demand attention:
Off-target Effects: Unintended DNA edits can have unforeseen consequences.
Eugenics: Misusing CRISPR for designer babies raises social and ethical questions.
Equity: High costs could limit access to this potentially life-saving technology.
The Path Forward: Responsible development is crucial:
International Collaboration: Clear guidelines are needed for research and human trials.
Public Education: Open discussions ensure informed decisions about CRISPR.
Prioritize Safety and Ethics: Safety and ethical principles must be paramount.
CRISPR offers a powerful tool for a better future, but responsible development and addressing ethical concerns are essential. By prioritizing safety, fostering open dialogue, and ensuring equitable access, we can harness CRISPR's power for the benefit of all. (2998 characters)

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

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.
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
50. Prevention & Control
Vector control
Habitats reduction
Individual and house hold protection
Clothing
Repellants
Mosquito nets
Insecticides
Windows/door screens
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.
