Positive Strand RNA Infection Open Access Journals

            Positive chain RNA virus is also known as a sensitive strand RNA virus, a virus whose genetic information consists of a single strand of RNA, a positive strand (or senses) that encodes mRNA (messenger RNA) and proteins. Replication of the positive strand of the RNA virus occurs through negative intermediaries. Examples of positive chain RNA viruses include polio virus, coxsackie virus and echovirus. There are two types of RNA viruses. Some of them are positive because they have a "semantic" direction in RNA (the building blocks of encoded proteins) as genetic material. Other RNA viruses are also negative because they have an "antisense" barrier (the opposite of encoded information). Therefore a positive or sensitive strand RNA virus is the opposite of a negative or antisense RNA virus. The viral RNA genome with positive sensation can function as messenger RNA and can be translated into proteins in host cells. SsRNA with positive feelings is included in group IV in the Baltimore classification. Positive RNA viruses represent most known viruses, including many pathogens such as hepacivirus C, West Nile virus, dengue virus, SAR and MERS corona viruses and SARS-CoV-2, as well as clinically less serious pathogens such as rhinoviruses cause cold.
