“…Majority of the respondents 91.6% uses face mask. This is similar to a study carried out in China 25 , where majority of the respondents (70.0%) use face mask. Among the respondents who never use a face mask, the majority (52.4%) said they often forgot to wear it and 47.6% said it was not necessary.…”

This study determines the prevalence of occupational diseases and safety practices among health workers of General Hospital, Minna. The study was Cross Sectional Descriptive. Stratified Sampling Technique was adopted. Semi structured questionnaire was used to collect data. Data were analyzed in frequency tables. The most common occupational disease among the respondents include: stress & exhaustion 61.2%, needle stick injury 52.8% and neck and low back pain 56.4%. Fortytwo point eight percent (42.8%) of the respondents have received at least one dose of Hepatitis B vaccine. Majority (57.2%) have never received the vaccine. There was no association between socio-demographic characteristics and the receipt of vaccine. About 18.4% of the respondents have been exposed to fluids of HIV/AIDS patients through needle stick injury. Majority of them (60.9%) have gone for post exposure prophylaxis against HIV. More than half of the respondents, 58.8% have been using Personal Protective Equipment (PPE). The study concludes that there is poor knowledge, attitude and high level of practice of control of occupational hazards among health workers who were examined. Health education and training of health workers on occupational hazards and their control should be enhanced.

“…Even though the use/reuse of cloth masks is common, especially in low resource countries such as, for example in China [76] and Vietnam [77,78], none of the guidelines reviewed covered the use of these products. Currently, there is a lack of data to either support or refute the effectiveness of woven cloth masks in blocking influenza or virus transmission and fluid resistance.…”

BackgroundCurrently there is an ongoing debate and limited evidence on the use of masks and respirators for the prevention of respiratory infections in health care workers (HCWs). This study aimed to examine available policies and guidelines around the use of masks and respirators in HCWs and to describe areas of consistency between guidelines, as well as gaps in the recommendations, with reference to the WHO and the CDC guidelines.MethodsPolicies and guidelines related to mask and respirator use for the prevention of influenza, SARS and TB were examined. Guidelines from the World Health Organization (WHO), the Center for Disease Control and Prevention (CDC), three high-income countries and six low/middle-income countries were selected.ResultsUniform recommendations are made by the WHO and the CDC in regards to protecting HCWs against seasonal influenza (a mask for low risk situations and a respirator for high risk situations) and TB (use of a respirator). However, for pandemic influenza and SARS, the WHO recommends mask use in low risk and respirators in high risk situations, whereas, the CDC recommends respirators in both low and high risk situations. Amongst the nine countries reviewed, there are variations in the recommendations for all three diseases. While, some countries align with the WHO recommendations, others align with those made by the CDC. The choice of respirator and the level of filtering ability vary amongst the guidelines and the different diseases. Lastly, none of the policies discuss reuse, extended use or the use of cloth masks.ConclusionCurrently, there are significant variations in the policies and recommendations around mask and respirator use for protection against influenza, SARS and TB. These differences may reflect the scarcity of level-one evidence available to inform policy development. The lack of any guidelines on the use of cloth masks, despite widespread use in many low and middle-income countries, remains a policy gap. Health organizations and countries should jointly evaluate the available evidence, prioritize research to inform evidence gaps, and develop consistent policy on masks and respirator use in the health care setting.

“…Facemasks fabricated from materials impregnated with an antimicrobial agent are a potential cost effective strategy to protect against the spread of TB (20). Antimicrobial facemasks may decrease the risk of TB transmission that occurs due to reuse of contaminated facemasks or reuse of facemasks that have been structurally compromised during decontamination (2,20,21).…”

Tuberculosis is considered a leading cause of death worldwide. More than 95% of cases and deaths occur in low-and middle-income countries. In resource-limited countries, hospitals often lack adequate facilities to manage and isolate patients with infectious tuberculosis (TB), relying instead on personal protective equipment, such as facemasks, to reduce nosocomial transmission of the disease. Facemasks impregnated with an antimicrobial agent may be a cost-effective way of adding an extra level of protection against the spread of TB by reducing the risk of disease transmission. Conducting polymers, such as polyaniline (PANI), and their functionalised derivatives are a novel class of antimicrobial agents with potential as non-leaching additives to provide contamination resistant surfaces. We have investigated the antimicrobial action of PANI and a functionalised derivative, poly-3-aminobenzoic acid (P3ABA), against mycobacteria and have determined the optimal treatment time and concentration to achieve significant knockdown of Mycobacterium smegmatis and Mycobacterium tuberculosis on an agar surface. Results indicated that P3ABA is a potential candidate for use as an antituberculoid agent in facemasks to reduce TB transmission.
