Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection results in a spectrum of clinical presentations. The effect of co-infection with parasites on the clinical features of COVID-19 is unknown. Methods: We prospectively enrolled consecutive COVID-19 patients and screened them for intestinal parasitic infections. Patients were followed during hospitalization for clinical outcomes. Patients with parasitic co-infection were compared to those without parasitic co-infection. The primary outcome was the proportion of COVID-19 patients who developed severe disease. Factors associated with the development of severe disease were determined by logistic regression. Results: A total of 515 patients with PCR-confirmed SARS-CoV-2 infection were screened for intestinal parasites, of whom 267 (51.8%) were co-infected with one or more parasites. Parasitic co-infection correlated inversely with COVID-19 severity. Severe COVID-19 was significantly higher in patients without parasites [47/248 (19.0%, CI: 14.52-24.35)] than in those with parasites [21/267 (7.9%, CI: 5.17-11.79)]; p<0.0001. There was a significantly higher proportion of patients who developed severe COVID-19 in the non-protozoa group [56/369 (15.2%, CI: 11.85-19.23)] as compared to the protozoa group [12/146 (8.2%, CI: 4.70-14.00)]; p=0.036. Significant higher proportion of the patients presented at baseline with severe COVID-19 in the helminth negative group [57/341 (16.7%, CI: 13.10-21.08)] than in the group with pre-existing helminth infection [11/174 (6.3%, CI: 3.51-11.11)]; p=0.001. In addition, after adjustment for age and presence of comorbidities, COVID-19 patients with any parasite co-infection [aOR 0.41 (95% CI: 0.22-0.77); p=0.006], or with protozoa co-infection [aOR 0.45 (95% CI: 0.21-0.98); p=0.044] as well as those with helminth co-infection [aOR 0.37 (95% CI: 0.17-0.80); p=0.011] had lower probability of developing severe COVID-19 compared with those without parasite, protozoa or helminth co-infection. Conclusion: Our results suggest that co-infection with parasitic co-infection appears to be associated with reduced COVID-19 severity. The results suggest that parasite-driven immunomodulatory responses may mute hyperinflammation associated with severe COVID-19.

Background: Timely infant testing for HIV is critical to ensure optimal treatment outcomes among exposed infants. While world health organization recommends HIV exposed infants to be tested between 4 to 6 weeks of age, in developing countries like Ethiopia, access to timely infant testing is still very limited. The study is intended to assess timely infant testing, testing for HIV at the 18th month, test results and factors influencing HIV positivity among infants born to HIV positive mothers in public hospitals of Mekelle, Ethiopia. Methods:A cross-sectional study design was employed on 558 HIV exposed infants, using consecutive sampling technique. A checklist was used to extract 4 years (Data were analyzed using SPSS version 20, and binary logistic regression model was used to examine the association of independent variables with the outcome variables. Results: Timely infant testing for HIV accounted for 346(62.0%). Mothers who attended antenatal care (AOR: 2.77; 95% CI: 1.17, 6.55) and who were counselled on feeding options (AOR: 2.01; 95% CI: 1.11, 3.65) were strongly associated with timely infant testing. Poor maternal adherence status was associated with infants' HIV positivity at the 18th month of antibody test (AOR: 15.93; 95% CI: 2.21, 94.66). Being rural resident (AOR: 4.0; 95% CI: 1.23, 13.04), being low birth weight (AOR: 5.64; 95% CI: 2.00, 16.71) and not receiving ARV prophylaxis (AOR: 4.70; 95% CI: 1.15, 19.11) were positively associated with the overall HIV positivity. Conclusions: A considerable proportion of exposed infants did not undergo timely testing for HIV. Antenatal care follow-up and counselling on feeding options were associated with timely infant testing. Mother's poor adherence status was associated with infant's HIV positivity at the 18th month of antibody testing. Being rural resident, being low birth weight, and not receiving ARV prophylaxis were the factors that enhance the overall HIV positivity. Timely infant testing, counselling on feeding options and adherence should be intensified, and prevention of mother-tochild transmission program in rural settings need to be strengthened.

Background Oligohydramnios is a state of deficient amniotic fluid defined objectively using ultrasound measurements as single deepest vertical pocket less than 2 centimeters and/or amniotic fluid index less than 5 centimeters. It has been correlated with conditions that threaten both maternal and fetal health. The aim of this stuy is to assess determinants of adverse maternal and perinatal outcome in women with oligohydramnios after 37+0 weeks in Ayder Comprehensive Specialized Hospital and Mekelle General Hospital from April 1, 2018 – March 31, 2019.Methods This was prospective observational study. Total population purposive sampling method was employed to collect data prospectively. Result During the study period, there were a total of 10,451 deliveries, of which 273 were complicated with oligohydramnios, making the prevalence of term oligohydramnios 2.6%. The composite adverse perinatal and maternal outcomes were 38.1% and 89.4% respectively. Primigravidity, degree of oligohydramnios, presence of intrauterine growth restriction and postterm pregnancy were associated with adverse perinatal outcome. Degree of oligohydramnios and hypertensive disorders of pregnancy were found to be predictor of composite adverse maternal outcome. Conclusion Appreciation of determinants of composite adverse maternal and neonatal outcome can aid prompt interventions and mobilization of resources for resuscitation and early transfer to neonatal intensive care unit. Knowledge of determinants of maternal outcome can serve as a tool for patient counseling and for anticipation of maternal complications.
