In this study, 400 students from two secondary schools in Kano State, Nigeria, were engaged with the aim of assessing their level of knowledge and attitudes regarding HPV infection. The study further seeks to understand the respondent's opinion on HPV vaccination and sensitize them to the health effects of HPV infection, thereby communicating the findings to the authorities concerned with policy making. The study revealed that only 128 (32%) and 142 (35.5%) respondents have knowledge about HPV and cervical cancer, respectively. Furthermore, none of the respondents were administered the HPV vaccine, with 81% of them not ready to take the vaccine. It was observed that the majority of the respondents (91%) believed that early hospital visits could help in mitigating HPV or cervical cancer cases. Following their sensitization, the respondents were observed to have different levels of satisfaction, ranging from very satisfied and satisfied to not satisfied.

Some common mutations were found in the organisms of the same phylum and among different phyla. Homology modeling of Rab7 proteins from different organisms was done using SWISS-MODEL and validated further by developing Ramachandran plots. Protein-protein docking showed that active residues were there in the binding interfaces of Rab7 from organisms of seven different phyla and VP28 of WSSV. Similarities were observed in the Rab7-VP28 complexes in those selected organisms which differed from the Rab7-VP28 complex in the case of Penaeid shrimp.

A cross-sectional survey followed by a simple random sampling technique was conducted from May to July 2021 on 384 apparently healthy nonvaccinated chickens on 30 smallholder poultry farms using commercial indirect ELISA kits and a questionnaire survey.

Although some mutations provide benefits to the virus against human immune response, others may result in their reduced pathogenicity and virulence. By analyzing more than 3000 high-coverage, complete sequences deposited in the GISAID database up to April 2020, here I report the uniqueness of the 28881-28883: GGG > AAC trinucleotide-bloc mutation in the SARS-CoV-2 genome that results in two substrains, described here as SARS-CoV-2g (28881-28883: GGG genotype) and SARS-CoV-2a (28881-28883: AAC genotype). Computational analysis and literature review suggest that this bloc mutation would bring 203-204: RG (arginine-glycine)>KR (lysine-arginine) amino acid changes in the nucleocapsid (N) protein affecting the SR (serine-arginine)-rich motif of the protein, a critical region for the transcription of viral RNA and replication of the virus. Thus, 28881-28883: GGG > AAC bloc mutation is expected to modulate the pathogenicity of SARS-CoV-2. These analyses suggest that SARS-CoV-2 has evolved into SARS-CoV-2a affecting COVID-19 infectivity and severity. To confirm these assumptions, retrospective and prospective epidemiological studies should be conducted in different countries to understand the course of pathogenicity of SARS-CoV-2a and SARS-CoV-2g. Laboratory research should focus on the bloc mutation to understand its true impacts on the course of the pandemic.
