Dengue fever has no specific treatment, but supportive care can help manage the symptoms. Only one vaccine, Dengvaxia® from Sanofi, has been approved by the FDA to prevent severe disease. It is approved for children aged 9 to 16 who live in an endemic area and have previously been infected with DENV as confirmed by a laboratory serological assay.
The number of Powassan virus (POWV) reported cases is low compared to other tick-borne diseases such as Lyme disease. However, the prevalence of POWV infection is likely underestimated because testing capabilities are limited. There are no FDA-cleared assays and only a few commercially available assays. There is a need to increase the awareness of POWV infection to include this testing in clinical routine labs.
Less than a year after the World Health Organization (WHO) declared COVID-19 a global pandemic, the authorization of several novel COVID-19 vaccines has created hope for a healthier future. Recent studies have demonstrated that both humoral and cellular immunity play a role in protection from COVID-19. Additionally, the development of novel COVID-19 vaccines requires a look at the immune response in order to determine the effectiveness of the vaccine at preventing infection.
SARS-CoV-2, commonly known as the coronavirus disease 2019 (COVID-19) poses an unprecedented public health crisis. While scientists and clinicians worldwide are still working to understand the virus, recent studies show possible onset of autoimmune diseases following COVID-19 infection.
