The COVID-19 Delta variant (B.1.617.2) is a highly contagious strain of the coronavirus that was first detected in India in October 2020 and has since spread to more than 60 countries. The Delta variant has several mutations in its spike protein that make it more infectious and able to evade some immune responses2.
Compared to the original virus, the Delta variant has been associated with higher viral loads, faster transmission, younger age groups, and increased hospitalizations and deaths. The Delta variant poses a serious threat to the global efforts to control the pandemic and requires urgent action to prevent its spread and mitigate its impact.
The symptoms of the Delta variant are similar to the symptoms of other variants of SARS-CoV-2, and include:
The best way to protect yourself from the Delta variant is to get vaccinated against COVID-19. The COVID-19 vaccines are highly effective at preventing serious illness, hospitalization, and death from COVID-19, including from the Delta variant.
Other ways to protect yourself from the Delta variant include:
If you think you may have the Delta variant, you should get tested for COVID-19. If you test positive, you should isolate yourself from others to prevent the spread of the virus. You should also contact your doctor to discuss your treatment options.
There is no cure for the Delta variant, but there are treatments that can help to relieve symptoms and prevent serious illness. These treatments include over-the-counter medications, such as ibuprofen and acetaminophen, and prescription medications, such as antiviral drugs and corticosteroids.
The recovery time for the Delta variant is similar to the recovery time for other variants of COVID-19, which is typically 2-4 weeks for most people. However, some people may experience longer-term symptoms, such as fatigue, shortness of breath, and difficulty concentrating.
Yes, the COVID-19 vaccines are effective at protecting against the Delta variant. However, it is possible to get a breakthrough infection, which is an infection that occurs in a vaccinated person. Breakthrough infections are usually mild, but they can be more severe in people who are elderly or have underlying medical conditions.
If you have been vaccinated and you are exposed to the Beta variant, you should monitor yourself for symptoms of COVID-19. If you develop any symptoms, you should get tested for COVID-19 and isolate yourself from others.
