SUMMARYThe effectiveness of environmental decontamination (ED) as a measure in the control of infectious diseases is controversial. This work quantifies the effectiveness of ED by analysing the transmission of pathogens from the environment to susceptible hosts in a Susceptible–Infected–Susceptible model. Analysis of the model shows that ED can render a population disease-free only when the duration of infection (D) is within a certain range. As host-to-host transmission rate is increased,Dfalls outside this range and the higher levels of ED have a diminishing return in reducing the number of infected hosts at endemic equilibrium. To avoid this, ED can be combined with other control measures, such as treating infected individuals to push the duration of infection into the specified range. We propose decision criteria and minimum ED efforts required for control policies to be effective.

Abstract Although identification of risks to dental healthcare workers has been explored in several industrialized nations, very little data is available from developing countries. This paper examines the occupational hazards present in the dental environment and reports survey results concerning attitudes and activities of a group of Nigerian dental care providers. A survey on occupational hazards was conducted among the clinical dental staff at the Dental Hospital of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife in Osun State, Nigeria. Thirty eight of the forty staff responded, yielding a response rate of 95%. Subject ages ranged from 26 to 56 years with approximately 25% in the 31-46 year old bracket. All of the staff were aware of the occupational exposure to hazards, and the majority had attended seminars/workshops on the subject. Only five staff members (13.2%) owned a health insurance policy and 26 (68.4%) had been vaccinated against Hepatitis B infection. All dentists (24) had been vaccinated compared with only two non-dentists; this relationship was significant (p= 30.07, x2=0.000). Fourteen members of the clinical staff (36.8%) could recall a sharp injury in the past six months, and the majority (71.1%) had regular contact with dental amalgam. Wearing protective eye goggles was the least employed cross infection control measure, while backache was the most frequently experienced hazard in 47% of the subjects. The need for Hepatitis B vaccinations for all members of the staff was emphasized, and the enforcement of strict cross infection control measures was recommended. The physical activities and body positions that predispose workers to backaches were identified and staff education on the prevention of backaches was provided. Citation Fasunloro A, Owotade FJ.

ABSTRACT Introduction CDC (Center for Disease Control & prevention), who proposed Universal Precautions, states that “Treat each patient as potentially risk”. Therefore, it is our basic responsibility to control the spread of such devastating diseases by following infection control measures. Aims & Objectives To assess the various personal protective measures adapted by dental practitioners in Agra city and to know how many dentists are vaccinated against Hepatitis B for prevention of the spread of this disease. Materials and Methods The study included response using questionnaire from 150 dental practitioners from Agra city, chosen by random sampling. Questions were related to their personal protective measures employed by the dental practitioners and information about their prophylaxis against Hepatitis B was also obtained. Results Among the dental practitioners, 80% were males. Approximately 82% of the dental practitioners were vaccinated against HBV. Only 6% followed the CDC recommendations for hand washing practices, and about 64% dental practitioners gave wrong answers related to droplet infection. Conclusion Lack of awareness regarding universal precautions proposed by CDC is observed among dental practitioners. There is a great need for creating awareness among dental practitioners.

Public Demand

It is a public demand to expect health care profession to maintain its highest possible standard by preventing the spread of communicable diseases. Dental laboratory, being a potential source for the spread of various infections, is no exception to it and should ensure strict infection control measures. In contrast to the dental clinic and surgical areas, the dental laboratory is often overlooked, especially, when planning effective infection control measure. The aim of this review is to provide the general dental practitioners with the latest information and guidelines to achieve infection control in the dental laboratory. Apparently, it focuses on the technical knowledge and practices that should be followed in prosthetic laboratories. DOI: http://dx.doi.org/10.3329/cdcj.v10i2.16347 City Dent. Coll.

Novel Coronavirus

A novel coronavirus (SARS-CoV-2) first detected in Wuhan, China, has spread rapidly since December 2019, causing more than 80,000 confirmed infections and 2,700 fatalities (as of Feb 27, 2020). Imported cases and transmission clusters of various sizes have been reported globally suggesting a pandemic is likely.Here, we explore how seasonal variation in transmissibility could modulate a SARS-CoV-2 pandemic. Data from routine diagnostics show a strong and consistent seasonal variation of the four endemic coronaviruses (229E, HKU1, NL63, OC43) and we parameterize our model for SARS-CoV-2 using these data. The model allows for many subpopulations of different size with variable parameters. Simulations of different scenarios show that plausible parameters result in a small peak in early 2020 in temperate regions of the Northern Hemisphere and a larger peak in winter 2020/2021. Variation in transmission and migration rates can result in substantial variation in prevalence between regions.While the uncertainty in parameters is large, the scenarios we explore show that transient reductions in the incidence rate might be due to a combination of seasonal variation and infection control efforts but do not necessarily mean the epidemic is contained. Seasonal forcing on SARS-CoV-2 should thus be taken into account in the further monitoring of the global transmission. The likely aggregated effect of seasonal variation, infection control measures, and transmission rate variation is a prolonged pandemic wave with lower prevalence at any given time, thereby providing a window of opportunity for better preparation of health care systems.

ABSTRACT Objective: The purpose of this study was to investigate compliance, awareness and practices of infection control procedures among senior dental students at the College of Dentistry, University of Sharjah, United Arab Emirates. Materials and Methods: The study comprised of 119 subjects of 4 th and 5 th year dental students. A questionnaire was developed with 25 open and closed-ended questions related to barrier techniques, vaccination status, infection control practices and awareness. This was distributed among the senior dental students and completed upon signing the consent form. Each questionnaire was coded to ensure the confidentiality of responses. Results: The questionnaire was distributed among 223 senior dental students at the University of Sharjah of which only 119 students (53%) responded. Compliance with the use of protective barriers was high with the exception of protective eye wear, utilized by a mere 27% of students. There was a significant difference between 4 th and 5 th year dental students′ attitudes (p < 0.05) regarding the treatment of patients with infectious diseases. Compared with 44.4% of the 5 th year students, 68.5% of the 4 th year students did not mind treating patients with infectious diseases. Owing to this, 61.9% of the 5 th year students suffered from non-sterile percutaneous and mucous membrane exposures compared with 44.6% of the 4 th year students (p < 0.05). Conclusions: Efforts are needed to improve attitudes, implement information and motivate students in the correct and routine use of infection control measures. With all infection control protocols already implemented in dental schools, the challenge remains on improving compliance with infection control recommendations.

The Impact

SUMMARYOne of the most pressing issues in facing emerging and re-emerging respiratory infections is how to bring them under control with current public health measures. Approaches such as the Wells–Riley equation, competing-risks model, and Von Foerster equation are used to prioritize control-measure efforts. Here we formulate how to integrate those three different types of functional relationship to construct easy-to-use and easy-to-interpret critical-control lines that help determine optimally the intervention strategies for containing airborne infections. We show that a combination of assigned effective public health interventions and enhanced engineering control measures would have a high probability for containing airborne infection. We suggest that integrated analysis to enhance modelling the impact of potential control measures against airborne infections presents an opportunity to assess risks and benefits. We demonstrate the approach with examples of optimal control measures to prioritize respiratory infections of severe acute respiratory syndrome (SARS), influenza, measles, and chickenpox.
