The PDF "COLERA: Informação para Promotores de Saúde" provides essential guidance for health promoters and activists on cholera. It explains that cholera is characterized by severe watery diarrhea, often resembling rice water, and sometimes vomiting. If not treated promptly, it can lead to death ...within hours. The disease affects both adults and children and spreads through contaminated feces, poor hygiene, and unsafe water or food. To prevent cholera, the document emphasizes the importance of drinking treated or safe water, cooking food thoroughly and keeping it covered, washing hands with soap or ash after using the latrine and before handling food, and using proper latrines or sanitary facilities. It also highlights the role of vaccination, recommending the oral cholera vaccine "Shanchol," which requires two doses 2–3 weeks apart. The vaccine is suitable for individuals over one year old, including pregnant women, and has minimal side effects such as mild abdominal pain or diarrhea. This resource aims to empower health promoters with practical knowledge to prevent and manage cholera outbreaks effectively.

Similar to other parts of the world, the prevalence of type 2 diabetes mellitus (T2DM) in the Asia-Pacific Region has rapidly increased during the last few decades. The purposes of this pilot study were to determine the feasibility and the effects of a capacity building program for Village Health Vo...lunteers (VHVs) to support self-management in a T2DM high risk population from a rural subdistrict in Northeast Thailand. Both quantitative and qualitative data were collected using surveys, focus group discussions, and in-depth interviews. Data were analyzed and used to develop a 12-week capacity building program for VHVs. This program was then implemented on 60 subjects at high risk of T2DM in the selected community. According to the paired t-test and Wilcoxon-signed rank test, VHVs had higher scores on knowledge and self-efficacy of T2DM prevention after a 12 week intervention (p =.03 and p =.02, respectively). Study participants at risk for T2DM also had a significant increase in T2DM knowledge and self-management (p <.001). Implementation of the capacity building program for VHVs in Northeast Thailand was feasible. The key successes were strong community bonding, community empowerment, and support from family and public health nurses. Effects of the program should be examined with those in other Asia-Pacific countries.

The new WHO recommendations for rabies immunization supersede the 2010 WHO position
on pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) for rabies. These updated
recommendations are based on new evidence and directed by public health needs that are cost-,
dose- and time-sparing..., while assuring safety and clinical effectiveness. In addition, new guidance on
prudent use of rabies immunoglobulins (RIG) is provided.
The following sections summarize the main points of the updated WHO position as endorsed by the
Strategic Advisory Group of Experts on immunization (SAGE) at its meeting in October 20171. The full
version of the WHO position on rabies vaccines and immunoglobulins will be published in the Weekly
Epidemiological Record2 in April 2018.
Rabies prevention involves two main strategies: (i) dog vaccination to interrupt virus transmission to
humans; and (ii) human vaccination as a series of vaccine administrations before or after an exposure.
Currently, rabies vaccines made from inactivated cell cultures are extremely well tolerated and have no
contraindications.

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition...al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

1PEP GUIDELINES | 2019 EDITION. The prevalence of both HIV and Hepatitis B is high in South Africa therefore there is a significant risk of acquiring these infections following exposure to infected material. Studies suggest that post- exposure prophylaxis (PEP) with highly active antiretroviral trea...tment (HAART) is highly effective in preventing HIV infection if taken correctly for the full recommended duration of 28 days, and that prophylaxis with Hepatitis B immunoglobulin and vaccination may prevent Hepatitis B infection if given soon after exposure. This update of the Western Cape guidelines for management of potentially infectious exposures is based on current evidence and guidelines issued by the WHO, NDoH and the SA HIV Clinicians Society. The key aim is to promote successful completion of the recommended ART regimen in the 28 day period of therapy, as well as prevent infection with Hepatitis B

The article "Effectiveness of one dose of oral cholera vaccine in response to an outbreak: a case-cohort study" investigates whether a single dose of the Shanchol oral cholera vaccine can provide effective protection during an outbreak. Conducted i...n Juba, South Sudan, in 2015, the study involved a case-cohort approach, analyzing vaccination status and disease outcomes.
Findings showed that a single dose was 80.2% effective in preventing medically attended cholera cases, increasing to 87.3% after adjustments for confounding factors. These results suggest that a single-dose strategy can be an effective emergency response, particularly in settings with limited vaccine supply and high mobility of affected populations. The study supports using a single-dose approach during outbreaks when a two-dose regimen is logistically challenging.

The technical note from the Global Task Force on Cholera Control (GTFCC) examines the risks and benefits of vaccinating pregnant women with WHO-prequalified oral cholera vaccines (OCVs) during mass vaccination campaigns. It highlights that three WHO-approved vaccines (Dukoral®, Shanchol™, and Euv...ichol®) offer sustained protection and a strong safety profile.
While these vaccines are not explicitly contraindicated for pregnant women, there is limited clinical data on their use during pregnancy. However, studies indicate that pregnant women with cholera face higher risks of fetal loss, stillbirth, and complications, especially if they experience severe dehydration. Some evidence suggests that vaccination can reduce cholera incidence in pregnant women and indirectly protect infants.
Although no controlled trials have focused on pregnant women, retrospective studies in Guinea and Zanzibar showed no significant increase in adverse pregnancy outcomes after OCV administration. The GTFCC concludes that the benefits of vaccination outweigh the risks, particularly in high-risk areas, and recommends including pregnant women in cholera vaccination campaigns while continuing to monitor safety data.

- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type ...for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

Background
The core clinical symptoms of addiction include an enhanced incentive for drug taking (craving), impaired self-control (impulsivity and compulsivity), emotional dysregulation (negative mood) and increased stress reactivity. Symptoms related to impaired self-control involve reduced activi...ty in anterior cingulate cortex (ACC), adjacent prefrontal cortex (mPFC) and other brain areas. Behavioral training such as mindfulness meditation can increase the function of control networks including those leading to improved emotion regulation and thus may be a promising approach for the treatment of addiction.
Methods
In a series of randomized controlled trials (RCTs), we tested whether increased ACC/mPFC activity is related to better self-control abilities in executive functions, emotion regulation and stress response in healthy and addicted populations. After a brief mindfulness training (Integrative Body-Mind Training, IBMT), we used the Positive and Negative Affect Schedule (PANAS) and Profile of Mood States (POMS) to measure emotion regulation, salivary cortisol for the stress response and fMRI for brain functional and DTI structural changes. Relaxation training was used to serve as an active control.
Results
In both smokers and nonsmokers, improved self-control abilities in emotion regulation and stress reduction were found after training and these changes were related to increased ACC/mPFC activity following training. Compared with nonsmokers, smokers showed reduced ACC/mPFC activity in the self-control network before training, and these deficits were ameliorated after training.
Conclusions
These results indicate that promoting emotion regulation and improving ACC/mPFC brain activity can help for addiction prevention and treatment.

South Africa is a mineral-rich country. Although the mining of these minerals generates wealth for the country, it also causes diseases in the mine workers who are exposed to harmful dust. Pulmonary silicosis, the disease most commonly caused by exposure to crystalline silica dust, was described in ...South African gold miners in the early 1900s not many years after gold-mining commenced. Most studies since then have been cross-sectional, with only one large cohort study being conducted on white miners; long-term trends have not been reported. Currently, South Africa has one of the highest rates of silicosis in the world.

For the molecular diagnosis of Chagas disease by real-time PCR (polymerase chain reaction), optimization of diagnostic accuracy is desirable. The detection limit of real-time PCR assays for the diagnosis of Trypanosoma cruzi in human serum is affected by various influences including the choice of th...e nucleic acid extraction assay. In this study, three nucleic acid extraction assays were compared regarding their influence on the sensitivity of a T. cruzi-specific real-time PCR with 62 reference sera containing T. cruzi target DNA (deoxyribonucleotide acid). More than 95% of the positive sera were correctly identified after all three nucleic acid extraction strategies with a detection rate ranging from 96.8% (60/62) for the worst assay to 100% (62/62) for the best one. A matched pairs analysis for the comparison of the cycle threshold (Ct) values obtained with the 59 reference samples with positive real-time PCR results after all three nucleic acid extraction schemes indicated differences in a range of about 3 Ct steps. Summarized, all three compared nucleic acid extraction schemes were basically suitable for T. cruzi-specific PCR from serum with some minor differences. However, in the case of low quantities of circulating parasite DNA in the serum of a patient with Chagas disease, even minor effects can make a difference in the individual diagnosis.
