Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Plasmodium species are the causative agents of coronavirus disease 2019 (COVID-19) and malaria respectively with similar clinical presentations. The objective of this study is to determine the burden of co-infection of SARS-CoV-2 and malaria in the general population. Five (5 mLs) of blood samples were collected for SARS-CoV-2 and malaria parasite test. The malaria test was performed using a commercially available one-step malaria antigen Plasmodium falciparum histidine-rich protein 2 (Pf HRP-II) rapid test kit. The results of the study showed that the participants that were coinfected with SARS-CoV-2 IgG and malaria were 13 (2.5%) in Lagos, 1114 (39.1%) in Delta and 49 (2.3%) in Sokoto States. The prevalence of coinfection of SARS-CoV-2 and malaria in urban areas in Lagos, Delta and Sokoto States were 7 (2.2%), 1373 (48.1%), and 5 (0.2%) respectively. In rural areas, the prevalence of coinfection of SARS-CoV-2 and malaria in Lagos, Delta and Sokoto States were 6 (0.3%), 365 (12.8%), and 44 (2.1%) respectively in this study. This suggests that participants in the urban areas were more prone to co-infections than the rural areas in Lagos and Delta states, while it was otherwise in Sokoto State. In conclusion, the co-infection of SARS-CoV-2 and malaria was very high in Delta State compared to the other States. It is important for clinics to screen for both diseases when patients present with symptoms of malaria. This is because the infections have similar symptoms and the public is quick to assume malaria infection without diagnosing for COVID-19 and vice versa.

The COVID-19 pandemic put every government in the globe on red alert;safety protocol and long-standing infection prevention and control (IPC) measures such as hand and oral hygiene, social/ physical distancing, use of face mask were rigorously enforced. This study evaluated microbial (bacterial, fungal) contents of rinsate, bowl water, water from tap, and the neighborhood drainage in selected hand washing stations in Agege, Alimosho, Mainland, Island and Shomolu local government areas (LGAs) in Lagos, Nigeria. The identities of bacterial isolates were confirmed with 16S rRNA sequencing while the fungi were identified by colonial appearances. The antibiotics susceptibility testing (AST) of the bacteria against structurally unrelated antibiotics was performed and interpreted according to standard guidelines. Sixty-seven (67) bacterial and fifty-one (51) fungal isolates were recovered from mainly water bucket with tap and rinsates across all the LGAs. There were marked microbial loads (some too numerous to count at 10-3 dilution) across Alimosho, Lagos Island and Mainland. Forty (40) representative bacterial isolates were selected for 16S rRNA sequencing. The occurrence of microbial isolates in the samples was at varying degrees;Klebsiella spp. (37.5%), Bacillus spp. (32.5%), Enterobacter spp. (17.5%), were the predominant bacteria while Aspergillus spp. (46.2%), yeasts (34.6%), Sporothrix schenckii (11.5%) and Penicillium spp. (7.7%) constituted the fungal isolates. The biological weapon, B. anthracis was recovered from a water bucket with tap in Alimosho. The antibiotics susceptibility testing of the bacteria showed high degrees of resistance profile;45 (69.2%) to ampicillin, 41.5% amoxicillin/clavulanate while 47.6% were resistant to two (2) or more antibiotics. This study demonstrated high microbial load during the pandemic at the study LGAs, presence of environmental commensals reputed for debilitating opportunistic infections in man and risk of passing

Introduction: Cervical cancer remains a major cause of morbidity and mortality among the female population in sub-Saharan Africa. Vaccination against human papillomavirus (HPV), the main causative agent, has the potential to eradicate cervical cancer. In-country evidence of sub-types of HPV associated with cervical cancer is scanty, thus necessitating this study. Methods: A cross-sectional study was performed using a multistage sampling technique. A molecular technique using the Cobas 4800 machine was used for genotyping. Results: 570 participants were recruited for the study. The mean age of the participants was 32.4 ± 5.2 years. The age of sexual debut ranged from 15 - 24 years with a median of 19 years. 194 participants were positive for high-risk HPV giving a prevalence of 34%. 3% (n = 17) were positive for HPV, 16. 4% (23) had a positive result for HPV, 18. 27% (n = 154) had a positive result for other high-risk groups (OHR) other than HPV 16 or 18. Positive status for high-risk HPV is associated with the presence of genital warts (OR = 7.5), a Positive HIV status (OR = 3.48), abnormal vaginal discharge (OR = 2.20), multiple sexual partners (OR = 2.30), and obesity (OR = 2.70). The prevalence of HIV in the study population was 6.84% (n = 39). Conclusion: Another High-risk HPV other than 16 and 18 appears to be the predominant form of HPV infection in Nigerian women. The risk of being positive for high-risk HPV is associated with the presence of genital warts, abnormal vaginal discharge, a positive HIV status, multiple sexual partners and Obesity. It is therefore necessary to disaggregate and study these high-risk sub-types.

Background: Access to testing for SARS-CoV-2 in Nigeria is still highly restricted. Only patients who are symptomatic for SARS-CoV-2 are selected for testing. This pattern of testing will miss a large proportion of individuals with the infection who are asymptomatic and presymptomatic. This study reports the experience of a symptom-based study from a large testing centre in Nigeria. Methods: A cross-sectional study, reviewing data collected from respondents presenting at the Nigerian Institute of Medical Research (NIMR) modified drive-through center for COVID-19 test between the period March 31st and August 31st, 2020 were included in the analysis. Results: A total of 9891 participants were recruited into the study and 2465 participants (24.9%) had a positive PCR result for SARS-CoV-2. The majority of the respondents were above 18 years old, n = 9163 (93.4%). The average age of the respondents was 36.7 years (sd 13.8 years). The age of the participants has a significant effect on SARS-CoV-2 status (AOR = 1.009, CI, 1.005 to 1.012, p = 0.0001). There was a male preponderance, n = 5652 (57.6%). The odds of having a positive status for SARS-CoV-2 were 0.9 times lower for female participants. The majority of the respondents had a history of travel, n = 6788 (68.6%). Cough was the commonest symptom, n = 1062 (10.7%) followed by fever, n = 979 (9.9%). The mortality rate was 0.1%. Among the participants with comorbidity, 31 (51.7%) had positive results for SARS-CoV-2 while 29 (48.3%) had negative results. Conclusion: Symptom-based approach to testing for SARS-CoV-2 in Nigeria revealed a high positivity rate, while mortality from those tested in the study is low. Age and gender appear to play a significant role in the dynamics of the disease.
