Dengue fever is the fastest emerging arboviral infection spread
by Aedes mosquitoes with major public health consequences in
over 100 tropical and sub-tropical countries in South-East Asia,
the Western Pacific, and South and Central America. Up to 2.5
billion people globally live under the threat of dengue fever and its
severe forms—dengue hemorrhagic fever (DHF) or dengue shock
syndrome (DSS). More than 75% of these people, or approximately
1.8 billion, live in the Asia-Pacific Region. As the disease spreads to
new geographical areas, the frequency of the outbreaks is increasing
along with changing disease epidemiology. It is estimated that 50
a million cases of dengue fever occur worldwide annually and half a
million people suffering from DHF require hospitalization each year,
a very large proportion of whom (approximately 90%) are children
less than five years old. About 2.5% of those affected with dengue
die of the disease.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.

2. Epidemiology
• In India first outbreak of dengue was recorded in 1812
• A double peak hemorrhagic fever epidemic occurred in India for the
first time in Calcutta between July 1963 & March 1964
• In New Delhi, outbreaks of dengue fever reported in 1967,1970,1982,
&1996
4. Dengue Virus
1. Causes dengue and dengue hemorrhagic fever
2. It is an arbovirus
3. Transmitted by mosquitoes
4. Composed of single-stranded RNA
5. Has 4 serotypes (DEN-1, 2, 3, 4)
5. Dengue Virus
•Each serotype provides specific lifetime immunity,
and short-term cross-immunity
•All serotypes can cause severe and fatal disease
•Genetic variation within serotypes
•Some genetic variants within each serotype appear
to be more virulent or have greater epidemic potential
6.
7. The most common epidemic vector of dengue in the world is
the Aedes aegypti mosquito. It can be identified by the white
bands or scale patterns on its legs and thorax.
8.
9. Aedes aegypti
•Dengue transmitted by infected female
mosquito
•Primarily a daytime feeder
•Lives around human habitation
•Lays eggs and produces larvae
preferentially in artificial containers
10. Clinical Characteristics of Dengue Fever
•Fever
•Headache
•Muscle and joint pain
•Nausea/vomiting
•Rash
•Hemorrhagic manifestations
Patients may also report other symptoms, such as
itching and aberrations in the sense of taste,
particularly a metallic taste. In addition, there have
been reports of severe depression after the acute
phase of the illness.
11. 1.The virus is inoculated into
humans with the mosquito
saliva.
2.The virus localizes and
replicates in various target
organs, for example, local
lymph nodes and the liver.
3.The virus is then released
from these tissues and
spreads through the blood to
infect white blood cells and
other lymphatic tissues.
4.The virus is then released
from these tissues and
circulates in the blood.
12. 5.The mosquito ingests blood containing the virus.
6.The virus replicates in the mosquito midgut, the ovaries,
nerve tissue and fat body. It then escapes into the body
cavity, and later infects the salivary glands.
7.The virus replicates in the salivary glands and when the
mosquito bites another human, the cycle continues.
13. The transmission cycle of dengue virus by the mosquito Aedes aegypti begins
with a dengue-infected person. This person will have virus circulating in the
blood—a viremia that lasts for about five days. During the viremic period, an
uninfected female Aedes aegypti mosquito bites the person and ingests blood
that contains dengue virus. Although there is some evidence of transovarial
transmission of dengue virus in Aedes aegypti, usually mosquitoes are only
infected by biting a viremic person.
Then, within the mosquito, the virus replicates during an extrinsic incubation
period of eight to twelve days.
The mosquito then bites a susceptible person and transmits the virus to him or
her, as well as to every other susceptible person the mosquito bites for the rest of
its lifetime.
The virus then replicates in the second person and produces symptoms. The
symptoms begin to appear an average of four to seven days after the mosquito
bite—this is the intrinsic incubation period, within humans. While the intrinsic
incubation period averages from four to seven days, it can range from three to 14
days.
The viremia begins slightly before the onset of symptoms. Symptoms caused by
dengue infection may last three to 10 days, with an average of five days, after the
onset of symptoms—so the illness persists several days after the viremia has
ended.
14.
15. There are actually four dengue clinical
syndromes:
1.Undifferentiated fever;
2.Classic dengue fever;
3.Dengue hemorrhagic fever, or DHF; and
4.Dengue shock syndrome, or DSS.
Dengue shock syndrome is actually a severe
form of DHF.
16. Clinical Case Definition for Dengue Fever
Classical Dengue fever or Break bone fever is an acute febrile
viral disease frequently presenting with headaches, bone or joint
pain, muscular pains,rash,and leucopenia
Clinical Case Definition for Dengue Hemorrhagic Fever
4 Necessary Criteria:
1. Fever, or recent history of acute fever
2. Hemorrhagic manifestations
3. Low platelet count (100,000/mm3 or less)
4. Objective evidence of “leaky capillaries:”
• elevated hematocrit (20% or more over baseline)
• low albumin
• pleural or other effusions
17. Clinical Case Definition for Dengue Shock Syndrome
•4 criteria for DHF
+
•Evidence of circulatory failure manifested indirectly by
all of the following:
•Rapid and weak pulse
•Narrow pulse pressure (< 20 mm Hg) OR
hypotension for age
•Cold, clammy skin and altered mental status
•Frank shock is direct evidence of circulatory failure
19. Signs and Symptoms of Encephalitis/Encephalopathy
Associated with Acute Dengue Infection
•Decreased level of consciousness:
lethargy, confusion, coma
•Seizures
•Nuchal rigidity
•Paresis
20. Four Grades of DHF
Grade 1
Fever and nonspecific constitutional symptoms
Positive tourniquet test is only hemorrhagic
manifestation
Grade 2
Grade 1 manifestations + spontaneous bleeding
Grade 3
Signs of circulatory failure (rapid/weak pulse,
narrow pulse pressure, hypotension,
cold/clammy skin)
Grade 4
Profound shock (undetectable pulse and BP)
21. Danger Signs in Dengue Hemorrhagic
Fever
•Abdominal pain - intense and sustained
•Persistent vomiting
•Abrupt change from fever to hypothermia,
with sweating and prostration
•Restlessness or somnolence
*All of these are signs of impending shock and
should alert clinicians that the patient needs close
observation and fluids.
22.
23. This thermometer illustrates the developments in the illness that are
progressive warning signs that DSS may occur.
The initial evaluation is made by determining how many days have passed
since the onset of symptoms.
Most patients who develop DSS do so 3-6 days after onset of symptoms.
Therefore, if a patient is seven days into the illness, it is likely that the worst
is over.
If the fever goes between three and six days after the symptoms began, this is
a warning signal that the patient must be closely observed, as shock often
occurs at or around the disappearance of fever.
Other early warning signs to be alert for include a drop in platelets, an
increase in hematocrit, or other signs of plasma leakage.
If you document hemoconcentration and thrombocytopenia and other signs
of DHF and the patient meets the criteria for DHF, the prognosis and the
patient's risk category have changed. Though dengue fever does not often
cause fatalities, a greater proportion of DHF cases are fatal.
The next concern would be observation of the danger signs—severe
abdominal pain, change in mental status, vomiting and abrupt change from
fever to hypothermia. These often herald the onset of DSS.
The goal of treatment is to prevent shock. The plasma leakage syndrome is
self-limited. If you can support the patient through the plasma leakage phase
and provide sufficient fluids to prevent shock, the illness will resolve itself.

25. Purpose of Control
•Reduce female vector density to a level
below which epidemic vector transmission
will not occur
•Based on the assumption that eliminating or
reducing the number of larval habitats in the
domestic environment will control the vector
•The minimum vector density to prevent
epidemic transmission

29. LABORATORY CRITERIA
• ISOLATION OF DENQUE VIRUS
• INCREASED IgM OR IgM ANTIBODIES TITRES
• DENQUE ANTIGEN DETECTION BY
IMMUNOHISTOCHEMISTRY,IMMUNOFLUROSCENCE,ELISA
• PCR
• LEUCOPENIA,THROMPOCYTOPENIA
30.
31. Vector Control Methods:
Biological and Environmental Control
•Biological control
•Largely experimental
•Option: place fish in containers to eat larvae
•Environmental control
•Elimination of larval habitats
•Most likely method to be effective in the long term
32. Vector Control Methods:
Chemical Control:
•Larvicides may be used to kill immature aquatic
stages
•Ultra-low volume fumigation against adult
mosquitoes
•Mosquitoes may have resistance to commercial
aerosol sprays
33. BIOLOGICAL CONTROL methods are not widely used and are primarily
experimental. One option in which biological control is often used,
however, is the placement of small fish that eat mosquito larvae in certain
containers, such as decorative fountains or 55-gallon drums. Recently, a
few countries have also reported success in controlling larvae with
copepods, small invertebrate crustaceans that feed on first- and second-
stage mosquito larvae.
ENVIRONMENTAL CONTROL involves eliminating or controlling the
larval habitats where the mosquito lays her eggs and the immature
mosquitoes develop. This includes emptying water from containers or
covering containers that are being used, cleanup campaigns to dispose
of containers that are not being used, and improving water supplies so
that there is less need to store water in containers. Since chemical
control is generally restricted to containers that cannot otherwise be
eliminated or managed, and biological control is still largely experimental,
environmental methods are likely to be the most effective for long-term
control of Aedes aegypti.
34. Larviciding involves placing chemicals into containers that cannot easily be
eliminated to kill the mosquito larvae.
Ultra-low volume, or ULV spraying of insecticides is widely practiced to kill
adult mosquitoes.
ULV spraying uses machines that produce very small particles of insecticide,
which are carried by wind currents.
Typically, ULV machines are either mounted on trucks or are portable
machines that can be carried by field workers.
The insecticide particles must come in contact with the mosquito to kill it.
Unfortunately, the Aedes aegypti mosquito tends to reside inside houses,
often resting in secluded locations such as closets that are not easily
penetrable by the insecticide spray.
Thus, ULV spraying from vehicles is generally ineffective, killing very few
Aedes aegypti mosquitoes.
The method is, therefore, expensive and ineffective.
Commercial aerosol sprays to kill the mosquitoes found indoors are useful,
but "knockdown resistance" may occur in some locations.
Individual householders may note that spray insecticide has only a
temporary effect, knocking down or paralyzing mosquitoes that later recover
and fly away.
In such cases, the sprayed mosquitoes must also be squashed to prevent
their recovery.
35. Although the goal of disease control is to prevent epidemic
transmission, if an epidemic does occur, ways to minimize its
impact include:
•Teaching the medical community how to diagnose and manage
dengue and dengue hemorrhagic fever (DHF), so they are better
prepared to effectively manage and treat large numbers of cases.
Mortality from DHF will thus be minimized.
•Implementing an emergency contingency plan to anticipate the
logistical issues of hospitalizing large numbers of patients and to
outline measures for community-wide vector control activities.
Such plans should be prepared with the participation of all parties
and agencies involved, and should be ready for implementation
prior to the emergence of an epidemic.
•Educating the general public to encourage and enable them to
carry out vector control in their homes and neighborhoods.
36. Programs to Minimize the Impact of Epidemics
•Education of the medical community
•Implementation of emergency contingency plan
•Education of the general population
