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.

COVID-19 Spread Patterns Is Unrelated to Malaria Co-Infections in Lagos, Nigeria

Malaria and COVID-19, though caused by different organisms, share a significant number of symptoms like fever, headaches, difficulty in breathing and fatigue. Therefore, determining if a patient is positive for COVID-19 or Malaria based on symptoms alone, might be misleading, especially during pandemic response. It has been reported that an individual begins to manifest Malaria symptoms between 10 - 15 days after infection with malaria parasite, although some individuals may be asymptomatic. Some COVID-19 infected patients, like Malaria, are also asymptomatic but could contribute to transmission of SARS-CoV-2 virus. These similarities in symptoms have led to misconception about COVID-19 being real and misdiagnoses of both infections, especially in Nigeria. However, there are possibilities that Malaria and COVID-19 could co-exist in some individuals thereby leading to mismanagement and treatment of only one infection while neglecting the possibility of the patient being infected with both diseases. We aim to determine possible correlation between Malaria and COVID-19 in a Malaria endemic country like Nigeria. This study was carried out using the qPCR molecular testing approach, a gold standard for COVID-19 testing and rapid diagnostic test kits to detect Malaria parasites in 617 individuals residing in urban settings. We demonstrated that COVID-19 and Malaria infection amongst adults in urban settings are unrelated thereby focusing on symptoms alone may result in misdiagnosis. Our findings show that Malaria is not among the underlying medical conditions strongly associated with increased risk for severe COVID-19 illness amongst adults in urban settings.

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 development of aquaculture in Nigeria is constrained by the inadequate supply of high quality of fingerlings of African catfish(Clarias gariepinus).There are conflicting reports on the reproductive efficacy of Vernonia amygdalina when compared with the synthetic hormone Ovaprim(OV)and Pituitary Extract(PE)on *** histopathology of select organs in catfish treated with generic Ovaprim(OV),Pituitary Extract(CPE),and aqueous extract of Vernonia amygdalina(VAE)were *** female ***(average weight of 1 kg)wereevenly and randomly distributed to four *** in groups A,B,C,and D were injected intramuscularly with aqueous solutions of OV(0.5 mL/kg),PE(5 mg/kg),VAE(10 mg/kg),and distilled water(DW;0.5 ml),*** examinations of the ovary,liver,kidney,and spleen were carried *** revealed that OV-and PE-treated groups showed synchronous and synchronous ovarian development,vacuolar change of hepatocytes,thinning of hepatic cords,reduced renal haemopoietic compartments,tubular degeneration and necrosis,and decrease in splenic periarteriolar lymphoid sheaths(PALS).VAE-treated groups had asynchronous ovarian development with atretic ovarian follicles,widespread vacuolar change of hepatocytes,intact renal tubular and hemopoietic compartments,and preponderance of large and coalescing splenic *** conclude that VAE is an ineffective spawning agent,especially when compared with OV and PE,as VAE could not induce synchronous gonadal ***,VAE may have immunopotentiating,nephroprotective,and haemopoietic properties.
