The Delta variant of the coronavirus is a highly infectious strain of the coronavirus that was found for the first time in India in December of 2020. It is also known by the name B.1.617.2. Since then, it has swiftly spread to other countries and has become the predominant strain in many regions of the world including the United States of America which has causes high number of death across worldwide.Here’s what you need to know about the Delta variant:
1. How it spreads:
The Delta version of the virus is more contagious than the virus that was originally discovered. It is possible for an infected individual to pass it on to others by respiratory droplets when they talk, cough or sneeze. Another method of transmission is coming into contact with a surface that is infected with the virus and then touching one’s own eyes, nose or mouth afterward.
The clinical manifestations of the Delta variant are akin to those of other strains of the coronavirus. The symptoms encompass fever, cough, dyspnea, cephalalgia, and anosmia or hyposmia. Notwithstanding, certain individuals infected with the Delta variant may encounter more acute symptoms, including respiratory distress and thoracic discomfort.
While vaccines do protect against the Delta variant, this protection may be less robust than against other strains of the virus. Two doses of the Pfizer-BioNTech or Moderna vaccine are demonstrated to offer good protection against the Delta form, but a single dose offers substantially lesser protection. It also indicates that the Johnson & Johnson vaccination has diminished efficacy against the Delta strain.
The optimal approach to curbing the transmission of the Delta variant is to receive vaccination if one meets the eligibility criteria. It is recommended to maintain good hygiene practises, including frequent hand washing, utilisation of masks in public settings, and refraining from attending large gatherings. In the event of illness, it is advisable to remain at home and refrain from interacting with individuals.
At present, there exist no targeted therapies for the Delta variant. The primary objective of treatment is to effectively manage the symptoms and mitigate the likelihood of complications. Individuals exhibiting severe symptoms may necessitate hospitalisation and the administration of oxygen therapy.
To summarise, the Delta variant of the coronavirus is a highly contagious strain that has emerged as the predominant variant in numerous regions globally. The efficacy of vaccines against the Delta variant is notable, although it may not be commensurate with their effectiveness against other viral strains. In order to mitigate the transmission of the Delta variant, it is imperative to receive vaccination if one meets the eligibility criteria, and to persist in observing proper hygiene measures.
