Viruses are the eventual assertion of parasitism, they not only take nutriments from the host cell, apart from that they direct its metabolic machinery to amalgamate novel virus particle and to diminish the ability of flu viruses to reproduce in an individual antiviral drugs are used. When used as directed, antiviral drugs may help to lessen the duration of flu symptoms and may reduce the severity of common flu symptoms. Antiviral drugs are the class of drugs which comes under the antimicrobials, and that also accommodates the larger group i.e. of antibiotics. They are broad-spectrum in nature and can be effective against a wide range of viruses. They can be used as a single drug as well as in combination of drugs. Antiviral drugs are dissimilar from the antibiotics, they do not demolish their target pathogen ideally they obstruct development of pathogen. To the greatest extent antiviral drugs currently accessible are delineate to deal with herpes viruses, covid-19, HIV, the hepatitis b and c viruses herpes simplex, small pox, picornavirus and influenza a and b viruses etc. Scientists are searching to drag out the range of antiviral to the other families of pathogens. They mainly act by inhibiting the attachment of viruses on cells, prevent genetic reproduction of virus, prevent viral protein production and vital for production of virus. The emanation of antiviral is generally the outcome about an appreciably expanded skills or proficiency of the generative, microscopic and atomic activity of organisms, allowing biomedical analyst to acknowledge the structure, mechanism of action and activity of viruses, significant progress within the procedure for come across the current drugs. Coronavirus 2019 (COVID 19) is highly infectious disease triggered by SARS-CoV-2 (severe acute respiratory syndrome) coronavirus 2 causing nearly 2.9 million deaths worldwide. With the emergence of SARS-CoV-2, the repurposing of antiviral drugs has come into picture.

Background: The evolution of COVID-19 vaccinations, which are mostly seen as crucial to curb the epidemic, is a result of remarkable and ground-breaking researches by scientists around the world. The main goal of this study was to identify the significant adverse reactions of these vaccines, specifically in Homo sapiens. background: The evolution of COVID-19 vaccinations, which are mostly seen as crucial to curb the epidemic, is a result of remarkable and ground-breaking performances by scientists around the world. Methods: In this research, a trial version of Qualtrics CoreXM software was used, and 18 questionnaires were prototyped as part of an online survey that was done in the northern part of India. objective: The main goal of this research project was to identify the significant adverse reactions to vaccines, specifically in Homo sapiens. Results: The dataset included survey responses from 286 vaccinated (Corbevax) respondents' samples detailing their demographics, daily activities, type of gastronomic preferences, and any prior illnesses. The data were collected between March 24, 2022, and April 26, 2022. After analysis, 70.98% of respondents who took the first dose of the medication experienced side effects, while 50.62% of respondents who took the second dose of the medication stated the same. The major side effects reported were injection site pain, fever, tiredness, body ache, headache, etc. method: In this research used a trial version of Qualtrics CoreXM software, 18 questionnaires were prototyped as part of an online survey that was done in the northern part of India. Conclusion: After conducting a poll on children (aged 12-18) who had received the COVID-19 vaccination, we concluded that immunizations rarely cause moderate side effects that are manageable. other: no

Citrus fruits of industrial interest include lemons, oranges, mandarins, grapefruits, clementines, limes and other commercially minor ones. A huge amount of agricultural waste is generated yearly all over the globe by citrus fruit industry. The wastes from these productions may be, however, of great nutritional and economic value for their chemical composition, due to their abundance of diverse functional compounds. Citrus canker, caused by the bacterium Xanthomonas citri subsp. citri, affects the leaves, twigs and fruit of citrus plants causing the leaves to drop and unripe fruit to fall to the ground. All types of citrus are affected by the disease.
