    Essential nutritive and immunological ingredients abundantly present in breastmilk make it the choice infant nutrition. The uniqueness of mother's milk, in contrast to most therapeutics and immunizations, lies in its potential to adapt itself to the requirements of the infant so that timely immune defenses are tapped from its constituents by immune regulation, modulation and immune acceleration to stimulate novel substances; these render it pertinent as defense when faced with challenging organisms. While it is appreciated that immunity can be transferred from mother to infant through breastmilk following maternal influenza vaccination, the immense benefits conferred by breastfeeding per se during influenza pandemics may not be fully valued. This is substantiated by debates and ambiguities for continued breastfeeding in the face of maternal influenza infections. This article emphasises the utmost importance of breastfeeding in viral pandemics in the light of the changing immunological strategies used by viruses at different times and the urgent need for such opportune defenses. The prolific interaction of its constituents is frequently understated as enormous advantages to the suckling infant.

    BACKGROUND: Recent pandemics have had far-reaching effects on the world's largest economies and amplified the need to estimate the full extent and range of socioeconomic impacts of infectious diseases outbreaks on multi-sectoral industries. This systematic review aims to evaluate the socioeconomic impacts of airborne and droplet-borne infectious diseases outbreaks on industries.

    METHODS: A structured, systematic review was performed according to the PRISMA guidelines. Databases of PubMed, Scopus, Web of Science, IDEAS/REPEC, OSHLINE, HSELINE, and NIOSHTIC-2 were reviewed. Study quality appraisal was performed using the Table of Evidence Levels from Cincinnati Children's Hospital Medical Center, Joanna Briggs Institute tools, Mixed Methods Appraisal Tool, and Center of Evidence Based Management case study critical appraisal checklist. Quantitative analysis was not attempted due to the heterogeneity of included studies. A qualitative synthesis of primary studies examining socioeconomic impact of airborne and droplet-borne infectious diseases outbreaks in any industry was performed and a framework based on empirical findings was conceptualized.

    RESULTS: A total of 55 studies conducted from 1984 to 2021 were included, reporting on 46,813,038 participants working in multiple industries across the globe. The quality of articles were good. On the whole, direct socioeconomic impacts of Coronavirus Disease 2019, influenza, influenza A (H1N1), Severe Acute Respiratory Syndrome, tuberculosis and norovirus outbreaks include increased morbidity, mortality, and health costs. This had then led to indirect impacts including social impacts such as employment crises and reduced workforce size as well as economic impacts such as demand shock, supply chain disruptions, increased supply and production cost, service and business disruptions, and financial and Gross Domestic Product loss, attributable to productivity losses from illnesses as well as national policy responses to contain the diseases.

    CONCLUSIONS: Evidence suggests that airborne and droplet-borne infectious diseases have inflicted severe socioeconomic costs on regional and global industries. Further research is needed to better understand their long-term socioeconomic impacts to support improved industry preparedness and response capacity for outbreaks. Public and private stakeholders at local, national, and international levels must join forces to ensure informed systems and sector-specific cost-sharing strategies for optimal global health and economic security.

    This study was designed to evaluate the health and economic benefits of a workplace vaccination programme against influenza funded by the employer. Employees of a Malaysian petrochemical plant volunteered to take part in this prospective, non-randomised, non-placebo-controlled study. Demographic and health information, including influenza-like symptoms, sick leave and post-vaccination adverse events were collected via questionnaires. Cost-benefit analyses were performed from the employer's perspective.

    RESULTS: A total of 1,022 employees took part in the study, with 504 choosing to be vaccinated against influenza, and 518 remaining unvaccinated. The rate of influenza-like illness (ILI) was lower among vaccinated (8.13%) than non-vaccinated subjects (30.31%). Fever and respiratory symptoms were associated with all ILI cases. ILI-related sick leave was taken by 58.54% of vaccinated employees with ILI and 71.34% of non-vaccinated employees with ILI. Vaccination was financially beneficial, with the employer saving up to US dollar 53.00 per vaccinated employee when labour costs only were considered. Savings rose to up to US dollar 899.70 when the operating income of each employee was also considered. Workplace vaccination of healthy adults against influenza had a clear impact on ILI rates, absenteeism and reduced productivity in this Malaysian company. The health benefits translated into financial benefits for the employer, with cost savings significantly outweighting the costs of the vaccination programme.

    Influenza seasonality in equatorial countries is little understood. Seasonal and alert influenza thresholds were determined for Malaysia, using laboratory-based data obtained from the Malaysia Influenza Surveillance System and a major teaching hospital, from 2011 to 2016. Influenza was present year-round, with no clear annual seasons. Variable periods of higher transmission occurred inconsistently, in November to December, January to March, July to September, or a combination of these. These coincide with seasons in the nearby southeast Asian countries or winter seasons of the northern and southern hemispheres. Changes in the predominant circulating influenza type were only sometimes associated with increased transmission. The data can provide public health interventions such as vaccines.

    Mass-media reports on an epidemic or pandemic have the potential to modify human behaviour and affect social attitudes. Here we construct a Filippov model to evaluate the effects of media coverage and quarantine on the transmission dynamics of influenza. We first choose a piecewise smooth incidence rate to represent media reports being triggered once the number of infected individuals exceeds a certain critical level [Formula: see text] . Further, if the number of infected cases increases and exceeds another larger threshold value [Formula: see text] ( [Formula: see text] ), we consider that the incidence rate tends to a saturation level due to the protection measures taken by individuals; meanwhile, we begin to quarantine susceptible individuals when the number of susceptible individuals is larger than a threshold value Sc. Then, for each susceptible threshold value Sc, the global properties of the Filippov model with regard to the existence and stability of all possible equilibria and sliding-mode dynamics are examined, as we vary the infected threshold values [Formula: see text] and [Formula: see text] . We show generically that the Filippov system stabilizes at either the endemic equilibrium of the subsystem or the pseudoequilibrium on the switching surface or the endemic equilibrium [Formula: see text] depending on the choice of the threshold values. The findings suggest that proper combinations of infected and susceptible threshold values can maintain the number of infected individuals either below a certain threshold level or at a previously given level.

    The influenza epidemic of 2006/'07 began late in the season, like the two previous influenza epidemics. In week 8 a peak of modest height was reached. As usual, the causal strains were mainly A/H3N2 viruses and to a lesser extent A/H1N1 and B viruses. A new A/H1N1 virus variant has emerged, an event that on average takes place only every 10 years. However, almost all A/H1N1 virus isolates belonged to the old variant and were similar to the vaccine virus. The A/H3N2 virus isolates appeared to deviate from the vaccine strain, but after antigenic cartographic analysis and correction for low avidity they proved also closely related to the vaccine strain. The few type B virus isolates belonged to the B/Yamagata/16/88 lineage, whereas the used B vaccine virus had been chosen from the B/Victoria/2/87 lineage. The vaccine therefore will have provided almost optimal protection against the circulating influenza A/H1N1 and A/H3N2 viruses but not against the influenza B viruses. For the 2007/'08 influenza season the World Health Organization has recommended the following vaccine composition: A/Solomon Islands/3/06 (H1N1) (new), A/Wisconsin/67/05 (H3N2), and B/Malaysia/2506/04.

    Assessment of schoolchildren's knowledge, attitudes, and practices towards influenza A (H1N1) is crucial as schools play a major role in spreading the infection. The aims of this study were to determine the level of knowledge, attitudes, and practices on influenza A (H1N1) and the factors associated with practices of preventive behavior.A cross sectional study was conducted from July until December 2010. Two public secondary schools for two districts in Kelantan, Malaysia were randomly selected. Data were collected using a self-administered questionnaire. The questionnaire consisted of five constructs: sociodemographic, risk factors of containing influenza A (H1N1) infection, knowledge, attitudes, and practices. The questionnaire had been te,sted for its construct validity and reliability. General linear regression was applied in the data analysis. A sample of 436 secondary school students were recruited in this study involved Malay students aged 16 years old. The total knowledge, attitudes and practices scores for the overall respondents were 69.4, 82.2, and 73.8%, respectively. The significant influencing factors for the practices of preventive behavior were attended talk on H1N1 and attitudes score.This study suggested that health education is important for promoting the health of adolescents and contributing to the overall health of the public so that they will take precautions against the H1N1 infection.

    Southeast Asia is a region with great potential for the emergence of a pandemic influenza virus. Global efforts to improve influenza surveillance in this region have documented the burden and seasonality of influenza viruses and have informed influenza prevention strategies, but little information exists about influenza vaccination guidelines and vaccine sales.

    BACKGROUND: Respiratory illness continues to exert a burden on hajj pilgrims in Makkah. The purpose of this study is to determine the prevalence of respiratory illness and its associated factors among Malaysian hajj pilgrims in 2013 and to describe its preventive measures.

    METHODS: A cross-sectional study was conducted in Makkah and Malaysia during the 2013 hajj season. A self-administered proforma on social demographics, previous experience of hajj or umrah, smoking habits, co-morbid illness and practices of preventive measures against respiratory illness were obtained.

    RESULTS: A total of 468 proforma were analysed. The prevalence of the respiratory illness was 93.4% with a subset of 78.2% fulfilled the criteria for influenza-like illness (ILI). Most of them (77.8%) had a respiratory illness of <2 weeks duration. Approximately 61.8% were administered antibiotics but only 2.1% of them had been hospitalized. Most of them acquired the infection after a brief stay at Arafat (81.2%). Vaccination coverages for influenza virus and pneumococcal disease were quite high, 65.2% and 59.4%, respectively. For other preventive measures practices, only 31.8% of them practiced good hand hygiene, ∼82.9% of pilgrims used surgical face masks, N95 face masks, dry towels, wet towels or veils as their face masks. Nearly one-half of the respondents (44.4%) took vitamins as their food supplement. Malaysian hajj pilgrims with previous experience of hajj (OR 0.24; 95% CI 0.10-0.56) or umrah (OR 0.19; 95% CI 0.07-0.52) and those who have practiced good hand hygiene (OR 0.35; 95% CI 0.16-0.79) were found to be significantly associated with lower risk of having respiratory illness. Otherwise, pilgrims who had contact with those with respiratory illness (OR 2.61; 95% CI 1.12-6.09) was associated with higher risk.

    CONCLUSIONS: The prevalence of respiratory illness remains high among Malaysian hajj pilgrims despite having some practices of preventive measures. All preventive measures which include hand hygiene, wearing face masks and influenza vaccination must be practiced together as bundle of care to reduce respiratory illness effectively.

    Influenza is an infectious disease that leads to an estimated 5 million cases of severe illness and 650,000 respiratory deaths worldwide each year. The early detection and prediction of influenza outbreaks are crucial for efficient resource planning to save patient's lives and healthcare costs. We propose a new data-driven methodology for influenza outbreak detection and prediction at very local levels. A doctor's diagnostic dataset of influenza-like illness from more than 3000 clinics in Malaysia is used in this study because these diagnostic data are reliable and can be captured promptly. A new region index (RI) of the influenza outbreak is proposed based on the diagnostic dataset. By analysing the anomalies in the weekly RI value, potential outbreaks are identified using statistical methods. An ensemble learning method is developed to predict potential influenza outbreaks. Cross-validation is conducted to optimize the hyperparameters of the ensemble model. A testing data set is used to provide an unbiased evaluation of the model. The proposed methodology is shown to be sensitive and accurate at influenza outbreak prediction, with average of 75% recall, 74% precision, and 83% accuracy scores across five regions in Malaysia. The results are also validated by Google Flu Trends data, news reports, and surveillance data released by World Health Organization.
