HIV compromises the immune system and leads to AIDS. The first AIDS case was reported in 1981 in New York. There are now approximately 37 million people living with HIV globally. HIV is transmitted through sexual contact, blood transmission, and from mother to child. While there is no cure for HIV, antiretroviral therapy can suppress the virus and prevent AIDS.
This presentation will cover the basics of HIV and AIDS. By the end of this presentation, we hope that everyone will understand what HIV and AIDS mean, how the virus is transmitted, and Saskatchewan HIV statistics.

Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV). Following initial infection, a person may not notice any symptoms or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged period with no symptoms. As the infection progresses, it interferes more with the immune system, increasing the risk of common infections like tuberculosis, as well as other opportunistic infections, and tumors that rarely affect people who have working immune systems. These late symptoms of infection are referred to as AIDS. This stage is often also associated with weight loss.
HIV is spread primarily by unprotected sex (including anal and oral sex), contaminated blood transfusions, hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding. Some bodily fluids, such as saliva and tears, do not transmit HIV. Methods of prevention include safe sex, needle exchange programs, treating those who are infected, and male circumcision. Disease in a baby can often be prevented by giving both the mother and child antiretroviral medication. There is no cure or vaccine; however, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy. Treatment is recommended as soon as the diagnosis is made. Without treatment, the average survival time after infection is 11 years.
In 2015 about 37.3 million people were living with HIV and it resulted in 1.2 million deaths. Most of those infected live in sub-Saharan Africa. Between its discovery and 2014 AIDS has caused an estimated 39 million deaths worldwide. HIV/AIDS is considered a pandemic—a disease outbreak which is present over a large area and is actively spreading. HIV is believed to have originated in west-central Africa during the late 19th or early 20th century. AIDS was first recognized by the United States Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade.
HIV/AIDS has had a great impact on society, both as an illness and as a source of discrimination. The disease also has large economic impacts. There are many misconceptions about HIV/AIDS such as the belief that it can be transmitted by casual non-sexual contact. The disease has become subject to many controversies involving religion including the Catholic Church's decision not to support condom use as prevention. It has attracted international medical and political attention as well as large-scale funding since it was identified in the 1980s.

"The global HIV/AIDS epidemic is an unprecedented crisis that requires an unprecedented response. In particular it requires solidarity -- between the healthy and the sick, between rich and poor, and above all, between richer and poorer nations. We have 30 million orphans already. How many more do we have to get, to wake up?"
-- Kofi Annan
If anybody suspects for HIV infection, he or she should contact a health expert working on HIV and looking ahead with confidential counseling and testing. It is important for the pregnant ladies to go for a HIV test before delivery.
Human immunodeficiency virus (HIV) is a lentivirus that causes acquired immunodeficiency syndrome (AIDS),a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.

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!

2. WHAT is AIDS ?
HIV- (Human Immunodeficiency Virus) the virus compromises the
body’s ability to handle disease and causes AIDS.
AIDS- AIDS is the final stage of HIV infection. When the immune
system CD4 cells drop to a low level, a person ability to fight
infection is lost.
3. HISTORY
AIDS is the biggest threat to mankind in last three decades.
The first case of aids was described from New York (USA) in 1981.
Due to its large population size, India has the third largest HIV
epidemic in the world
There were approximately 36.9 million people living with HIV at the
end of 2017 with 1.8 million people becoming newly infected in 2017
globally reported by WHO.
4. TYPES OF HIV
•HIV-1 and HIV-2 are the two main
types of HIV.
•HIV-1 is the most widespread type
worldwide. HIV-2, a less prevalent
and less pathogenic (disease-causing)
type, is found principally in western
Africa.
•HIV-2 is becoming more common in
India.
5. SYMPTOMS
When HIV emerges from latency (The
period when someone with HIV
shows no signs of it) symptoms can
include:
Dry, flaky skin
Chronic fatigue
Fever that comes and goes (pyrexia)
Diarrhoea that lasts more than a
week
Heavy night sweats
Rapid weight loss
Swollen lymph nodes
White spots on tongue, mouth
& throat
6. HIV CAN BE TRANSMITTED BY
Sexual Mode- 75 %
Blood Transfusion- 5 %
Percutaneous/Mucosal- 5 %
Perinatal Mode- 20-40 %

8. WHICH BODY FLUID CONTAIN HIV ?

fluids. we know that the following fluids can contain
high levels of HIV-
Blood

Pre-seminal fluid
Breast milk
Vaginal fluids
Rectal (anal) mucous

contain enough HIV to infect you, unless they have
blood mixed in them and you have significant and
direct contact with them. healthcare workers may be
exposed to some other body fluids with high
concentrations of HIV, including:
Amniotic fluid
CSF
Synovial fluid
10. HIV CANNOT BE TRANSMITTED BY
Casual contact
Sharing food or water
Kissing and Touching

12. TREATMENT
There is no cure for HIV.
Anti-retroviral therapy can
reduce the presence of the virus
in the body, but can not
eliminate it.
