What is the role of HIV and TB in HIV treatment?
HIV medicines protect the immune system and prevent HIV from advancing to acquired immunodeficiency syndrome (AIDS). In people with HIV and latent TB infection, treatment with HIV and TB medicines reduces the chances that latent TB infection will advance to TB disease.
What is the current management of HIV-associated tuberculosis (TB)?
The current management of patients with HIV-associated TB includes provision of effective anti-TB treatment, use of concurrent ART, prevention of HIV-related comorbidities, management of drug cytotoxicity and prevention/treatment of IRIS (Lawn et al. 2013).
Should people with HIV/TB coinfection be treated for HIV and TB?
People with HIV/TB coinfection should be treated for both HIV and TB; however, when to start treatment and what medicines to take depends on a person’s individual circumstances. Taking certain HIV and TB medicines at the same time can increase the risk of drug-drug interactions and side effects.
What are the prevention interventions for tuberculosis (TB)?
Prevention of TB requires prevention interventions for both HIV infection and TB, including HIV counseling and testing, disclosure and partner testing, behavior modification, earlier antiretroviral therapy, and the "Three I's for HIV/TB": isoniazid preventive treatment, intensified case finding, and infection control for TB.
What program was implemented by the WHO to Stop TB?
The Stop TB Strategy, launched on World TB Day in 2006, is designed to meet the TB-related Millennium Development Goal (MDG) as well as the Stop TB Partnership targets set for 2015.
What is the correlation between HIV infection and tuberculosis?
HIV weakens the immune system, increasing the risk of TB in people with HIV. Infection with both HIV and TB is called HIV/TB coinfection. Untreated latent TB infection is more likely to advance to TB disease in people with HIV than in people without HIV.
What factors contributed to the resurgence of TB cases between 1985 and 1992?
This resurgence was fueled by the following factors: The onset of the human immunodeficiency virus (HIV) epidemic; • Increases in immigration of persons from countries where TB disease was common; • TB transmission in congregate settings; and • The development of multidrug-resistant (MDR) TB.

Always cover your mouth with a tissue when you cough or sneeze. Seal the tissue in a plastic bag, then throw it away. Wash your hands after coughing or sneezing. Don't visit other people and don't invite them to visit you.
WHO report on tuberculosis in Nigeria?
According to WHO reports, an estimated 63,000 Nigerians living with HIV/AIDS develop TB, while about 39,000 die from the disease, each year (WHO, 2018). To further compound the problem, Nigeria is ranked among the 10 countries that accounted for 77% of the global gap in TB case detection and notification in 2016.
What raised the incidence of tuberculosis from 1985 to 1992?
Human immunodeficiency virus infection had the greatest impact on TB morbidity among whites, blacks, males, and persons 25 to 44 years of age. From 1985 through 1992, the number of cases among children 4 years old or younger increased 36%, suggesting that transmission of TB increased during this period.
WHO tuberculosis epidemiology?
Worldwide, TB is the 13th leading cause of death and the second leading infectious killer after COVID-19 (above HIV/AIDS). In 2020, an estimated 10 million people fell ill with tuberculosis (TB) worldwide. 5.6 million men, 3.3 million women and 1.1 million children. TB is present in all countries and age groups.
How was tuberculosis controlled?
Environmental controls include technologies for the removal or inactivation of airborne M. tuberculosis. These technologies include natural ventilation, local exhaust ventilation, general ventilation, HEPA filtration, and ultraviolet germicidal irradiation (UVGI).
What is tuberculosis CDC?
Tuberculosis (TB) is a disease caused by bacteria called Mycobacterium tuberculosis. People with TB can spread it in the air to others when they cough, speak, or sing. You can get sick when you breathe TB bacteria into your lungs.
How is TB prevented from CDC?
Travelers should avoid close contact or prolonged time with known TB patients in crowded, enclosed environments (for example, clinics, hospitals, prisons, or homeless shelters). Although multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB are occurring globally, they are still rare.
Abstract
The opportunities for human immunodefiency virus (HIV) care and treatment created by new treatment initiatives promoting universal access are also creating unprecedented opportunities for persons with HIV-associated immunosuppression to be exposed to patients with infectious tuberculosis (TB) within health care facilities, with the attendant risks of acquiring TB infection and developing TB disease.
Risk of M. Tuberculosis Transmission
The occupational risk of TB for health care workers has been reported since the early 20th century. In 1928, an investigation in Norway found that 95% of 220 student nurses acquired TB infection, as documented by tuberculin skin test conversion, by their graduation, and 22% developed TB disease [ 11 ].
TB Infection Control
As noted above, the likelihood of persons with unsuspected infectious TB spending time in HIV care facilities currently being established in resource-constrained settings, with the attendant risk of spread of M. tuberculosis to other immunocompromised patients or to staff, is high.
The Need for Additional Research
The current level of knowledge about the most effective TB infection control practices in resource-limited settings is far from complete. However, operational research can further inform practice. Areas in which carefully collected and analyzed data would be useful include the following:
Beyond Health Care Settings
Although this discussion focuses on health care settings in an era of expanding ART, these same persons come together in many other institutional settings where transmission is as likely and where similar interventions are possible.

Why do we need TB medicine?
TB medicines are used to prevent latent TB infection from advancing to TB disease and to treat TB disease. The choice of TB medicines and the length of treatment depend on whether a person has latent TB infection or TB disease. People with HIV/TB coinfection should be treated for both HIV and TB; however, when to start treatment ...
How does HIV medicine help?
HIV medicines protect the immune system and prevent HIV from advancing to AIDS . In people with HIV and latent TB infection, treatment with HIV and TB medicines reduces the chances that latent TB infection will advance to TB disease.
What is it called when a person with TB is inactive?
Once in the body, TB can be inactive or active. When the TB bacteria is inactive, this is called latent TB infection. When the TB bacteria is active, this is called TB disease.

How many people will be treated with HIV in 2020?
As of September 30, 2020 as part of PEPFAR, CDC supported antiretroviral treatment for 10.5 million people living with HIV – more than one third of all people on treatment worldwide.
How does HIV treatment affect the quality of life?
Timely diagnosis of HIV infection and sustained antiretroviral treatment increases the quality of life for a person living with HIV and prevents the spread of the virus. Putting a person living with HIV on antiretroviral treatment is the first step towards achieving viral load suppression – a reduction of HIV in the body to undetectable levels. Research shows that suppressing HIV to undetectable levels virtually eliminates transmission of the virus to sexual partners. [2] As of September 30, 2020 as part of PEPFAR, CDC supported antiretroviral treatment for 10.5 million people living with HIV – more than one third of all people on treatment worldwide.
What is the purpose of pre-exposure prophylaxis?

Although HIV is preventable, there were more than 1.6 million new HIV infections worldwide in 2019, including 150,000 new infections in children. [1] To control the global HIV epidemic, the rate of new infections must be reduced worldwide. As a key implementing agency of the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), the U.S. Centers for Disease Control and Prevention (CDC) works in more than 45 countries and regions to support evidence-based prevention interventions shown to reduce new HIV infections and tailored to meet the distinct needs of diverse communities.
