Background: COVID-19 vaccination has been recommended for children to protect them and to enable in-person educational and social activities., Methods: We estimated COVID-19 vaccination effectiveness (VE) against school absenteeism in children 5-17 years old hospitalized from September 1, 2021 through May 31, 2023. Full vaccination was defined as two vaccine doses., Results: We studied 231 children admitted to hospital with COVID-19, including 206 (89.2 %) unvaccinated/partially vaccinated and 25 (10.8 %) fully vaccinated. Unvaccinated/partially vaccinated children were absent from school for longer periods compared to fully vaccinated children (median absence: 14 versus 10 days; p-value = 0.05). Multivariable regression showed that full COVID-19 vaccination was associated with fewer days of absence compared to no/partial vaccination on average (adjusted relative risk: 0.77; 95 % CI: 0.61 to 0.98). COVID-19 VE was 50.7 % (95 % CI: -11.3 % to 78.2 %) for school absenteeism above the median duration of absenteeism., Conclusions: Full COVID-19 vaccination conferred protection against school absenteeism in hospitalized school-aged children with COVID-19., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objectives: Our aim was to estimate vaccination and susceptibility rates against vaccine-preventable diseases among healthcare personnel (HCP) in eight hospitals., Methods: Cross-sectional survey., Results: A total of 1284 HCP participated (physicians: 31.3%, nursing personnel: 36.6%, paramedical personnel: 11.1%, administrative personnel: 13.2%, supportive personnel: 7.3%). Vaccination rates were 32.9% against measles and mumps, 38.1% against rubella, 5.7% against varicella, 9.2% against hepatitis A, 65.8% against hepatitis B, 31.8% against tetanus-diphtheria, 7.1% against pertussis, 60.2% against influenza, and 80.1% against COVID-19. Susceptibility rates were as follows: 27.8% for measles, 39.6% for mumps, 33.4% for rubella, 22.2% for varicella, 86.3% for hepatitis A, 34.2% for hepatitis B, 68.2% for tetanus-diphtheria, and 92.9% for pertussis. Older HCP had higher susceptibility rates against mumps, rubella, varicella, hepatitis A, hepatitis B, tetanus-diphtheria, and pertussis (p-values <0.001 for all). Mandatory vaccinations were supported by 81.85% of HCP., Conclusions: Although most HCPs supported mandatory vaccinations, significant vaccination gaps, and susceptibility rates were recorded. The proportion of susceptible HCP to measles, mumps, rubella, and varicella has increased in the past decade, mostly because of reduction in acquired cases of natural illness. Vaccination programs for HCP should be developed. A national registry to follow HCP's vaccination rates is urgently needed.

This study deals with the assessment of the role and potential contribution of-valuable and recyclable items-waste pickers (scavengers) in the overall recycling sector of solid waste management in Gaza Strip, Palestine. The analytical descriptive approach was applied in this study to achieve this goal. A special questionnaire was designed to record the views and activities of a statistically representative sample of scavengers, to determine their socio-economic conditions, their job satisfaction level, and their role in waste management. Together with that, the legal issues arising from their activity are investigated and conducted interviews with stakeholders/officials highly contributed to this. The results showed that the scavengers are mostly men, working informally for themselves, and do not belong to any official body or informal local association, yet their contribution was calculated to be 1-7.7% as far as the recyclable diversion rate is considered. According to the processed data, 34.1% of them are collecting from community bins distributed along the streets and from random dumpsites, 15.1% are collecting from random dumps only, and 12.7% are collecting from community bins distributed along the streets in addition to the random dumps and transfer stations. The monetary outcome is less than NIS 500 (New Israeli Shekels-NIS) monthly for approximately 72% of them. Taken into consideration that 91% of them are originating from a bad economic status, the aforementioned income-however low-is considered important for their live-hood. The results also showed that 93% of them are dissatisfied with their job due to mainly the district of residence, the negative attitude receipt by community members, and the low selling price of recyclable materials. The analysis is a stepping stone for scavengers' incorporation to the official waste management sector, providing them orientation and on-the-job training, in addition to the government support through tax incentives to the private sector which is highly recommended in developing countries. Such activities will certainly lead further development of the recycling sector, a wide range of circular economy pattern application locally, and elevation of their financial/life status.

This study deals with the occupational health and safety of valuable and recyclable waste collectors (called scavengers) in the Gaza Strip, Palestine. The analytical descriptive approach was used in this study to achieve this goal. Waste pickers in the study area are working informally at existing dumpsites, solid waste transfer stations, landfills, and community streets' bins areas. A sample of 301 scavengers was surveyed filling a structured questionnaire designed for this purpose, during individual interviews. In addition, interviews with key Palestinian officials in the Gaza Strip have been conducted to provide accurate data and comprehensive information regarding waste pickers activities. The results showed that the occupational health and safety of the waste pickers is in constant deterioration mainly due to the informal nature of their work. The waste pickers are reportedly suffering in the current situation and the majority has no access to potable water, sanitation, and hygienically appropriate place to sleep and have meals. None of them has ever received occupational health and safety training. The study recommends that local decision makers should uptake short-term and long-term measures in waste management sector both aiming at improving this vulnerable social group's health and safety life status., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2020 Issam A.

Palestine, being a developing country, faces lots of obstacles and deficiencies in the existing solid waste management (SWM) field. In wake of these circumstances, it seems hard for the public sector to run sustainable SWM systems. The overall objective of the research presented in this paper was to study the current status of the SWM field in the West Bank of Palestine under the perspective of potential private sector involvement. For this purpose, twelve Joint Service Councils (JSCs) for solid waste management were investigated. Out of them, only two are currently having a Public-Private Partnership (PPP) contract for the management and operation of the transfer station and the sanitary landfill. On the other hand, two JSCs are currently making arrangements and implementing studies for future PPPs on waste-to-energy, biowaste management and recycling projects. Jenin and Tubas Joint Service Council (JSC) had 3-month-duration PPP contract for the implementation of a recycling project, which is a worst case scenario as it failed to meet its objectives. The parameters that could encourage JSCs or ease the implementation of PPP in local SWM field are analysed. Overall conclusion is that sustainability can be accelerated once the government-represented by the Ministry of Local Government (MoLG)-is involved; providing legal support to local authorities and incentives to potential contractors in order to encourage them to join PPPs. Parameters that are believed to facilitate PPPs include the following: development or updating existing laws and regulations, facilitation of licensing procedures, and activation of the Investment Promotion Law. Feasibility and market analysis study implementation will indicate the appropriate actions required locally to achieve environmental and financial sustainability in all contracted PPPs.

Forecasting of hospital solid waste generation is a critical challenge for future planning. The composition and generation rate of hospital solid waste in hospital units was the field where the proposed methodology of the present article was applied in order to validate the results and secure the outcomes of the management plan in national hospitals. A set of three multiple-variable regression models has been derived for estimating the daily total hospital waste, general hospital waste, and total hazardous waste as a function of number of inpatients, number of total patients, and number of beds. The application of several key indicators and validation procedures indicates the high significance and reliability of the developed models in predicting the hospital solid waste of any hospital. Methodology data were drawn from existent scientific literature. Also, useful raw data were retrieved from international organisations and the investigated hospitals' personnel. The primal generation outcomes are compared with other local hospitals and also with hospitals from other countries. The main outcome, which is the developed model results, are presented and analysed thoroughly. The goal is this model to act as leverage in the discussions among governmental authorities on the implementation of a national plan for safe hospital waste management in Palestine., (© The Author(s) 2016.)

Municipal solid waste (MSW) piling up is becoming a serious problem in all developing countries (DC) as a result of inequitable waste collection and treatment. Citizens' collaboration is partly based on understanding their views and their active involvement in MSW planning; on the other hand the assessment of the perception of hazardousness related with MSW is considered rather important as well since the identification of the weak points of the applied MWM strategy is eased and the level of required training is determined. Researchers implemented a case study in the West Bank (WB) and Gaza Strip (GS) regions of Palestine, taking into consideration previous researches in other developing countries. They reached to safe and useful conclusions regarding the parameters which mean the greatest in the waste management field as far as DC are concerned. Lack of skilled manpower, irregular collection services, inadequate equipment used for waste collection, inadequate legal provisions, and resource constraints are additional factors that are confirmed to be challenging the waste management scenarios in all DCs today. The research takes those factors under consideration but focuses on the educational gap and the results revealed interesting trends a significant relationship between respondent's educational attainment and their awareness of hazardous waste (hazard perception); the results will indicate the measure taking required to avoid accidents occurred in those regions (burns from toxics, cuts from sharps, etc). National policy and legislation development based on the research outcomes will ensure equitable and accessible services are in place in order to move towards a healthier environment. Specialized health education and training programs on national scale are also needed to enhance awareness on hazardous waste., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

Because of many limitations, the siting, construction and operation of a new solid waste management (SWM) facility is a significant challenge in Palestine. A SWM facility should operate in a sustainable in all aspects, including social acceptance, environmental protection, financial equity, and, in this particular case study, the political acceptance of all regional parts is extremely important. This article presents the outcomes of an extended study that aimed to investigate the concerns and attitudes of the residents of Hebron governorate related to the entire lifecycle of SWM facilities. A structured questionnaire was developed based on literature reviews and was distributed to residents in three different communities in the same governorate with various lifestyle backgrounds. The overall investigation focused on the collection of raw data regarding citizens' levels of concern regarding the environmental impacts of SWM facilities, the general waste management aspects, the benefits gained by the operation of various types of SWM facilities and the attitudes during the construction period of each facility. The results show that concerns about water pollution are significant; the benefits gained as a result of the operation of SWM facilities, particularly the heat supply from incinerators, are welcomed; and 'not in my backyard' syndrome is highlighted. The outcomes of this research are input data for the development of a roadmap that may include educational programs, incentive schemes and active public involvement during all phases of the implementation of SWM facilities (planning, siting, operation), in order to also ensure public acceptance, participation and regional sustainable development.

The primary goal of managing MSW incineration residues is to avoid any impact on human health or the environment. Incineration residues consist of bottom ash, which is generally considered as rather harmless and fly ash which usually contains compounds which are potentially harmful for public health. Small quantities of ash (both bottom and fly) are produced currently in Greece, mainly from the healthcare waste incineration facility in Attica region. Once incineration plants for MSW (currently under planning) are constructed in Greece, the produced ash quantities will increase highly. Thus, it is necessary to organize, already at this stage, a roadmap towards disposal/recovery methods of these ash quantities expected. Certain methods, related to the treatment of the future generated ash which are more appropriate to be implemented in Greece are highlighted in the present paper. The performed analysis offers a waste management approach, having 2016 as a reference year for two different incineration rates; 30% and 100% of the remaining MSW after recycling process. The results focus on the two greater regions of Greece: Attica and Central Macedonia. The quantity of potential future ash generation ranges from 137 to 459 kt for Attica region and from 62 to 207 kt for central Macedonia region depending on the incineration rate applied. Three alternative scenarios for the treatment of each kind of ash are compiled and analysed. Metal recovery and reuse as an aggregate in concrete construction proved to be the most advantageous -in terms of economy-bottom ash management scenario. Concerning management of the fly ash, chemical treatment with phosphoric solution addition results to be the lowest total treatment cost and is considered as the most profitable solution. The proposed methodology constitutes a safe calculation model for operators of MSW incineration plants regardless of the region or country they are located in., (Crown Copyright © 2012.
