Severe Acute Respiratory Syndrome Corona Virus-2 infection is a universal threat in recent days, hence early diagnosis and treatment play a pivotal role in controlling the spread thereby preventing them to become endemic. A newer promising approach by Nanotechnology plays an essential role in targeting the specific pathogens for therapeutic and diagnosis of Viral infection. Certain Nano platforms like Microneedle array delivered Virus S1 subunit vaccines, spike protein nanoparticles, Lumazine synthase Nanoparticles, Silver Nanoparticles, Self-Assembling Protein Nanoparticles against Viral therapy are the upcoming applications as a therapeutic approach. Nucleic acid amplification techniques and Surface-enhanced Raman Spectroscopy shows a high specificity with the immunoassay strategy. In recent days, Colloidal Gold – Nanoparticles and silicon nanoparticles have been widely used as a point of care for quick detection of IgG and IgM antibodies obtained from the virus as a diagnostic approach. Additionally, the Nanoparticles serve as a significant improvement in Personal Protective Equipment and protect against exposure to the virus. As a result of repurposing as well as for the development of the drug, apparently, Nanoparticles themselves and their concomitant therapy or their carriers will be advantageous in making a therapeutic and diagnostic approach against Severe Acute Respiratory Syndrome Corona Virus-2 infections.

Every country had to make several difficult decisions in the initial phase of the Coronavirus (COVID-19) pandemic to allocate resources for COVID testing. Decisions on who should be tested for COVID-19 testing are extremely vital for pandemic preparedness. In this article, we highlight the need for prioritization of testing resources including direct-to-consumer testing methods, ethical dilemmas involved in obligatory testing, and testing of refugees and immigrants.

The pandemic on SARS-CoV-2 infection has adversely impacted mankind all over the globe and more importantly, amidst individuals having Type-2 diabetic mellitus (T2DM) as well as among those who produce SARS-CoV-2 intricacies. Humoral and T cell-mediated immunity are adaptive immunity has a pivotal role to play in removing pathogens, comprising SARS-CoV-2. The infected cells are being eliminated by the primarily cytotoxic CD8+ T cells as well as certain antibodies in opposition to SARS-CoV-2 among humoral immunological responses possess the capacity for neutralizing this virus or by eliminating the infected cells with the support of cytotoxic in order to manage the progression of the disease. This cross-sectional study was carried out between January 2022 to December 2022. The serum samples were used to analyze SARS-CoV-2 total Ab among individuals having and not having T2DM and several metabolic risk factors like hypertension using WANTAI SARS-CoV-2 Total Ab ELISA Kit. There were 354 individuals, of which 141 (39.8%) had T2DM and 213 (60.2%) were nondiabetic patients. T2DM showed reduced antibody levels (average 5 AU/ml) than those without diabetes (average 12 AU/ml). SARS-CoV2 total antibody levels are considerably lower in hypertension patients (8 AU/ml) over those who are normotensive (14 AU/ml). The present study implies that the continuous monitoring of the total antibody profile of SARS-CoV-2 that may be a practical strategy to help individuals with T2DM and hypertension to determine their need of precautionary doses for sustaining SARS-CoV-2 vaccines by producing immunity for protection against infections.

Klebsiella is a pathogen that causes a significantly high number of community-acquired and hospital-acquired infections, with infections being one of the leading causes of death in ICU patients worldwide due to increasing antibiotic-resistance and a lack of therapeutic options. A total of 230 Klebsiella spp. were collected from various clinical samples. After initial identification, the drug-resistant strain was subjected to standard Clinical Laboratory and Standards Institute methods such as Kirby–Bauer disc diffusion. All isolates were screened and confirmed for ESBL/AmpC β-lactamase/carbapenemase production. The isolated Klebsiella spp. were found to be K. pneumonia (89%), K. oxytoca (6.5%), and K. aerogenes (4.5%). Among the 230 isolates, 80 (34.7%) isolates were found to be ESBL producers via screening; of these, 53 (23.5%) were verified by a confirmatory test. Moreover, 115 isolates (50%) were screened as AmpC producers; of these, 23 isolates (10%) were verified by a confirmatory test. Carbapenemase producers accounted for 69 (30%) isolates, identified by screening; 25 (10.86%) were verified by a confirmatory test. ESBL producers accounted for the majority of Klebsiella spp. isolates, followed by carbapenem and AmpC producing strains.
