Dengue is a mosquito-borne viral infection transmitted by Aedes mosquitoes, causing flu-like symptoms. It occasionally develops into a potentially lethal complication known as severe dengue or "break-bone fever". Epidemics occurred as early as the 18th century in Asia, Africa, and North America. There are four types of the dengue virus. While most age groups and both sexes can be affected, children are at higher risk than adults. The disease occurs more frequently during and after the rainy season in India. There is no specific treatment, but fluid intake, rest, and antipyretics are used. A licensed dengue vaccine was approved in 2015 but further analysis found it may increase risk
Dengue or break-bone fever is a mosquito-borne disease that is caused by the biting of Dengue infected mosquito. Symptoms typically begin three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.
Dengue is a viral infection transmitted by the bite of an Aedes mosquito infected with any one of the four dengue viruses. It occurs in tropical and sub-tropical areas of the world. It is mandatory to have great insight and awareness of dengue causes, dengue tips, and dengue prevention. Dengue in Pakistan has become an epidemic especially in Lahore Punjab. Dengue in Lahore has caused hundreds of deaths and has become uncontrollable. Therefore, dengue information should be spread like a wild fire through all mediums of information like TV, radio, internet, etc.
Dengue (pronounced DENG-gay) can affect anyone but tends to be more severe in people with compromised immune systems. Because it is caused by one of four serotypes of virus, it is possible to get dengue fever multiple times. However, an attack of dengue produces immunity for a lifetime to that particular serotype to which the patient was exposed.

Now a days.All the World is facing a serious problem..Dengue
so i make a presentation on dengue to prevent and aware from dengue...and if you have dengue faver then which types of treatment you use for your Health.
A mosquito-borne viral disease occurring in tropical and subtropical areas.
Spreads by animals or insects
Requires a medical diagnosis
Lab tests or imaging often required
Short-term: resolves within days to weeks
Those who become infected with the virus a second time are at a significantly greater risk of developing severe disease.
Symptoms include high fever, headache, rash and muscle and joint pain. In severe cases there is serious bleeding and shock, which can be life threatening.
Treatment includes fluids and pain relievers. Severe cases require hospital care.
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.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

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!

NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
3. • Dengue is a mosquito-borne, viral infection
transmitted by Aedes mosquitoes.
• The infection causes flu-like illness, and occasionally
develops into a potentially lethal complication called severe
dengue.
• Common name of the disease is ‘break-bone fever’ .
4. HISTORY
• Epidemics of an illness resembling dengue occurred in
1779, 1780 in three continents- Asia, Africa and North
America.
• First epidemic of DHF occurred in Manila, Philippines
1950.
• In India dengue virus was first isolated in Calcutta in 1945.
• Epidemic of Dengue hemorrhagic fever(DHF) first
occurred in Calcutta in 1963.

8.
9. It is caused by a virus (Dengue Virus) Four different types
(Type 1,2,3,4)
AGE & SEX GROUPS AFFECTED
• All age groups & both sexes are affected
• Children > Adults
• Female > Male (severe)
• Deaths are more in children during DHF outbreak
• Immune status
10.
11.
12. Disease occurs more frequently in the rainy season
and immediately afterwards (July to October) in
India.
13.
14.
15. • Fever: continuous for 3 to 7 days
• Severe headache
• Joint pain, muscle pain, pain behind eyeballs
•Nausea, vomiting, and rash
• In very rare cases, the condition may worsen into
dengue haemorrhagic fever, leading to internal bleeding,
shock, or even death.
16. •Blood pressure
•Evidence of bleeding in skin or other sites
•Hydration status
•Evidence of increased vascular permeability-
pleural effusions, ascites
•Tourniquet test
18. •At present, no specific drug that can treat dengue
fever effectively.
• Patient should be isolated in a mosquito-free
environment to prevent the spread of disease.
20. • No licensed vaccine at present
• Recently Tetravalent Dengue Vaccine phase 3
trial completed in Asia.
21. The first dengue vaccine, Dengvaxia® (CYD-TDV) developed by Sanofi Pasteur was licensed
in December 2015 and has now been approved by regulatory authorities in 20 countries
for use in endemic areas in persons ranging from 9-45 years of age.
In April 2016, WHO issued a conditional recommendation on the use of the vaccine for
areas in which dengue is highly endemic as defined by seroprevalence of 70% or higher.
In November 2017, the results of an additional analysis to retrospectively determine
serostatus at the time of vaccination were released. The analysis showed that the subset
of trial participants who were inferred to be seronegative at time of first vaccination had a
higher risk of more severe dengue and hospitalizations from dengue compared to
unvaccinated participants.
