Non-pharmaceutical strategies win coronavirus disease 2019 battle in New Zealand.

This literature-based article found that on 08 June 2020, New Zealand claimed victory over coronavirus disease 2019 (COVID-19) mainly because of effective non-pharmaceutical strategies and interventions that included a hard lockdown. The response was informed by the country's Influenza Pandemic Plan (although without criticism), which was updated in 2017, and the swift responses from political leadership and other key stakeholders. Strategies instituted included the proclamation of urgent precautionary measures leading to border closures, issuing of a 3-month-long COVID-19 notice under the Epidemic Preparedness Act 2006, the proclamation of the COVID-19 Elimination Strategy and the Initial COVID-19 Maori Response Action Plan, which incorporated COVID-19 Alert Levels that facilitated stepwise easing of the hard lockdown. The non-pharmaceutical strategies seem to have worked again, even as the second wave of COVID-19 infections returned in August 2020 through an Auckland cluster. Hence, the New Zealand case remains one that the world can draw lessons from, although not perfect.

Validation of a culturally modified short form of the McCarthy Scales of Children's Abilities in 6 to 8 year old Zimbabwean school children: a cross section study.

BACKGROUND: The burden of cognitive impairment among school children from developing communities is under reported due to lack of culturally appropriate screening tools. The objective of this study was to validate a culturally modified short form of the McCarthy Scales of Children Abilities (MSCA) in school children aged 6-8 years from varied backgrounds. METHODS: One hundred and one children aged 6-8 years attending mainstream classes were enrolled cross-sectionally from three schools: one rural and two urban. Two assessments were conducted on each child and the Short form MSCA was compared to an independent assessment by the educational psychologist. RESULTS: When comparing the results of the MSCA to local standard at -2SD, -1.5 SD and -1SD the sensitivity rates ranged from 17 to 50% with lower sensitivity at -2SD cut-off point. Specificity rates had less variation ranging from 95% to 100%. The number of children identified with cognitive impairment using -2SD, -1.5SD and -1SD below the mean for MSCA as a cut-off point were 3(3%), 7(7%) and 13(13%) respectively while the psychologist identified 18 (18%). The overall mean score on MSCA was 103 (SD 15). The rural children tended to score significantly lower marks compared to their peers from urban areas, mean (SD) 98(15) and 107(15) respectively, p=0.006. There was no difference in the mean (SD) scores between boys and girls, 103(17) and 103(15) respectively, p=0.995. CONCLUSION: The culturally modified short form MSCA showed high specificity but low sensitivity. Prevalence of cognitive impairment among 6 to 8 year children was 3%. This figure is high when compared to developed communities.

Neurodevelopmental impairment among infants born to mothers infected with human immunodeficiency virus and uninfected mothers from three peri-urban primary care clinics in Harare, Zimbabwe.

AIM: The aim of this article is to document the risk of neurodevelopmental impairment (NDI) among infants enrolled in a programme for the prevention of mother-to-child transmission of HIV (human immunodeficiency virus) in Zimbabwe using the Bayley Infant Neurodevelopmental Screener (BINS). METHOD: We prospectively followed up infants at three primary care clinics in Harare, Zimbabwe. Neurodevelopmental assessments using the BINS were conducted during the first 12 months of life. NDI risk category and associated risk factors were examined. RESULTS: Of the 598 infants assessed, 305 (51%) were female and 293 (49%) were male. Sixty-five infants (11%) were infected with HIV, 188 (31%) were exposed but uninfected, 287 (48%) were unexposed, and 58 (10%) were of unknown status. The prevalence of a high risk of NDI was 9.4% (95% confidence interval [CI] 7.1-11.1%): 9.2% in males and 9.6% in females. Of the 598 infants, 549 (92%) had ever been breastfed, 49% of whom had mothers infected with HIV. The risk of NDI was higher among infants infected early with HIV, i.e. by 3 months of age (p value <0.001). The NDI high-risk category included twice as many infants infected with HIV as uninfected infants (odds ratio [OR] 2.1; 95% CI 1.0-4.3). After adjusting for other factors, head circumference and family financial subsistence remained risk factors for NDI with an OR of 2.22 (1.04-4.82) and 2.55 (1.02-6.36) respectively. INTERPRETATION: The background prevalence of high-risk NDI category of 9.4% across groups seems high but is similar to that reported previously in developing countries. Integration of an early infant neurodevelopmental screening programme into child HIV management protocols will assist in the early referral of children exposed to HIV.
