National Hepatitis Testing Day: rapid hepatitis C testing

Leave a comment

The use of rapid hepatitis C virus tests could be a powerful tool for conducting hepatitis C screening, conveying prevention information, and initiating treatment in a population with high prevalence of hepatitis C infection, according to a study of persons at increased risk for infection in Wisconsin.

An estimated 3.2 million persons in the United States are infected with hepatitis C. Most new hepatitis C transmissions occur among injection drug users, often within the first few years of their injection drug use. During 2003–2012, reports of hepatitis C infection increased from 15 to 54 cases per 100,000 among persons under age 30 years in Wisconsin, and 58 percent of persons in this age group with acute hepatitis C reported injecting drugs.

To increase hepatitis C detection, the Wisconsin Division of Public Health piloted a program during October 2012–October 2013 that offered rapid hepatitis C testing to persons with drug dependence. Of these, 20 percent had positive hepatitis C test results—72 percent of the infections had not been reported previously—and 70 percent of those that tested positive had active infection.

The study found that use of the rapid test detected previously unreported infections and raised awareness of hepatitis C. Persons identified with active hepatitis C infection should be referred to medical care and counseled on ways to prevent transmission to others.

Positive impact of mass media campaign on bed net use in Cameroon

1 Comment

A mass media health education intervention in support of investments in malaria control commodities such as insecticide-treated mosquito bed nets can result in significant, large-scale positive health changes, according to a study conducted in Cameroon.

Approximately 298,000 adults and more than 221,000 of their children under age five slept under a bed net because of the knowledge, motivation, and/or timely reminder provided by KO Palu NightWatch activities.

The health communication program cost less than $0.16 per adult reached, and less than $1.62 per additional person protected by a net.

According to the World Health Organization’s World Malaria Report 2011, every one of Cameroon’s 19.6 million citizens is at risk of malaria, with 71 percent of them living in high transmission areas. More than 1.8 million suspected cases of malaria were recorded countrywide in 2010, along with over 4,500 recorded malaria-attributed deaths. Malaria was estimated to be responsible for 19 percent of under-five child deaths in 2008, more than any other single cause.

Slowdown in fight against malaria

Leave a comment

An effective concerted effort to strengthen malaria control globally in the last decade has had the greatest impact in countries with high malaria transmission. Close to 60 percent of the 1.1 million lives saved during this period were in the 10 highest burden countries. However, the expansion of funding for malaria prevention and control has leveled off in recent years, and progress in the delivery of some life-saving commodities has slowed. These developments are signs of a slowdown that could threaten to reverse the recent gains in the fight against one of the world’s leading infectious diseases, according to the World Malaria Report 2012.

World Malaria Report 2012The number of long-lasting insecticidal neets delivered to endemic countries in sub-Saharan Africa dropped from a peak of 145 million in 2010 to an estimated 66 million in 2012. The expansion of indoor residual spraying programs also leveled off, with coverage levels in the World Health Organization (WHO) African Region staying at 11 percent of the population at risk (77 million people) between 2010-2011.

The malaria burden is concentrated in 14 endemic countries, which account for an estimated 80 percent of malaria deaths. The Democratic Republic of the Congo and Nigeria are the most affected countries in sub-Saharan Africa, while India is the most affected country in South-East Asia.

The report indicates that international funding for malaria appears to have reached a plateau well below the level required to reach the health-related Millennium Development Goals and other internationally-agreed global malaria targets.

While the plateauing of funding is affecting the scale-up of some interventions, the report documents a major increase in the sales of rapid diagnostics tests, from 88 million in 2010 to 155 million in 2011, as well as a substantial improvement in the quality of tests over recent years. Deliveries to countries of artemisinin-based combination therapies (ACTs), the treatment recommended by the WHO for the treatment of falciparum malaria, also increased substantially, from 181 million in 2010 to 278 million in 2011, largely as a result of increased sales of subsidized ACTs in the private sector.

The report summarizes information received from 99 countries with on-going transmission and other sources, and updates the analyses presented in the 2011 report. Malaria is an entirely preventable and treatable vector-borne disease. In 2010, an estimated 219 million cases occurred globally, while the disease killed about 660,000 people, mostly children under age five years.

Motivating HIV testing among MSM using internet and mobile phones

Leave a comment

Men who have sex with men (MSM) have the highest HIV prevalence in Peru, yet they are underserved by traditional preventive programs. In Peru, the Internet and mobile phones have emerged as an effective and convenient tool to reach this population. A study published in PLoS ONE identifies five key themes that should be considered when designing an effective campaign to motivate HIV testing.

  1. Overcome fear of getting tested for HIV. Previous studies identify “fear of the consequences of a positive test result” as the main barrier for not getting tested among MSM. Since the 1980s, HIV testing campaigns in Peru have focused on fear, stigmatizing the disease and causing people to avoid getting tested out of fear of being positive. Future campaigns need to counteract this by providing motivational messages that transmit calmness and explain that HIV is now a chronic and treatable disease.
  2. Increase risk perception. MSM with high-risk practices often do not perceive themselves at risk. A brief explanation on the modes of transmission along with messages that can prompt participants to remember common risk situations they may have experienced would be useful to better understand the risks.
  3. Explain logistics. A successful campaign should include the marketing of the personnel, the place, information about the process, including the test itself, and the price of testing. The personnel include the professionals who will perform the HIV test and who will provide the results. The place includes the physical location where the test will be conducted, the operating hours, general attractiveness, comfort and accessibility. The price refers not only to monetary cost but also intangible costs such as embarrassment and psychological strain.
  4. Avoid stigmatizing and stereotyping content. Avoid language that implies gay men are promiscuous or more likely to have HIV. Use neutral characters (not stereotyped caricatures of gay men), as well as neutral language (absence of gay-related jargon) because either they were considered stigmatizing for gay-identified MSM, or because they will not feel identified within the heterosexually-identified MSM.
  5. Use appropriate layout and language. Study participants recommended that all text based information, when possible, should always be presented with images. Language should be simple and colloquial but not vulgar. The Layout should avoid the use of red, dark or gloomy colors. When possible, use humor because it makes information easier to understand and to remember.

These results serve as the basis to design an effective campaign to motivate HIV testing among gay and non-gay identified MSM in Lima, Peru, the study concludes.

Stigma, discrimination against HIV-positive patients by healthcare providers

Leave a comment

Equipping healthcare providers with knowledge of HIV, through the provision of protocols and trainings, is of paramount importance in reducing stigma and discrimination against people living with HIV amongst healthcare providers, according to a study conducted in Southwest Ethiopia.

The healthcare providers who were aware of anti-stigma and anti-discrimination rules and regulations were less likely to contribute to stigma and discrimination.

The study also found that healthcare providers share stigma and discrimination not only related to their occupation but also present in their communities. This implies that community-based anti-stigma and anti-discrimination interventions may also be helpful.

The study makes the following recommendations for ministries/departments of health at the national, regional, or local levels, as well as healthcare institutions and non-governmental organizations working with HIV-positive patients:

  • Make available protocols related to HIV to each healthcare provider in healthcare settings.
  • Orient healthcare providers about the contents and relevance of the HIV-related policies.
  • Provide the opportunity for trainings on stigma and discrimination to healthcare providers from time to time.
  • Extend HIV-related care and support services and anti-discrimination interventions to local areas.
  • Involve people living with HIV and religious leaders in these activities.

And lastly, healthcare providers themselves should strive to update their knowledge on HIV/AIDS.
