Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti

ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

Limited research has examined factors associated with psychological distress following natural
disasters among non-Western child populations. Conditions associated with trauma-related symptoms following the 2004 tsunami in a sample of 265 Sri Lankan child survivors (53.6% female, aged 3 to 17) were

examined retrospectively. Multivariate regression analyses identified pre-traumatic conditions (female gender, prior health) and peritraumatic conditions (loss of family, complete property loss) as being associated with increased trauma-related symptoms. Findings can be applied to the identification of children most at risk of developing trauma-related symptoms following a natural disaster from a non-Western population to aid development of culturally-appropriate interventions.

Already 20 billion of cancellation of foreign order makes the situation worse. Also, the foreign remittance has been decline dramatically due to the loss of jobs of Bangladeshi workers in foreign countries. The overall economic situation declines in this country due to the COVID-19 which has huge impact on the health care system especially in maternal and child health. In this paper, the economic situation of Bangladesh before and during the COVID-19 has been shown. Also, how the COVID-19 would affect the condition
