New strain of coronavirus
There have been several new strains of coronavirus identified since the COVID-19 pandemic began. Here are some of the most notable ones:
- Alpha variant (B.1.1.7): This variant was first identified in the UK in December 2020 and has since spread to many countries around the world. It is more contagious than the original strain of the virus and has been linked to increased hospitalizations and deaths.
- Beta variant (B.1.351): This variant was first identified in South Africa in December 2020 and has since been detected in several countries, including the US, UK, and Australia. It has been shown to be more contagious than the original strain and may be more resistant to some vaccines.
- Gamma variant (P.1): This variant was first identified in Brazil in November 2020 and has since been detected in several countries, including the US, UK, and Europe. It has been linked to increased hospitalizations and deaths, particularly in older adults and those with underlying health conditions.
- Delta variant (B.1.617.2): This variant was first identified in India in December 2020 and has since spread to many countries around the world. It is more contagious than the original strain and has been linked to increased hospitalizations and deaths, particularly in unvaccinated individuals.
- Mu variant (B.1.621): This variant was first identified in Colombia in January 2021 and has since been detected in several countries, including the US, UK, and Europe. It has been shown to be more contagious than the original strain and may be more resistant to some vaccines.
- Omicron variant (B.1.1.529): This variant was first identified in South Africa in November 2021 and has since spread to many countries around the world. It is more contagious than the original strain and has been linked to increased hospitalizations and deaths, particularly in unvaccinated individuals.
It's important to note that while these new strains of coronavirus are concerning, the vast majority of people who contract COVID-19 will experience mild to moderate symptoms and recover without serious complications. Vaccination remains the most effective way to prevent severe illness and death from COVID-19.
It's also important to note that the World Health Organization (WHO) and other global health authorities closely monitor the emergence of new variants and provide guidance on how to mitigate their spread.
