Test kit for detection of specific IgM to SARS-CoV-2 by immune blotting in the «Line blot» format has been developed. A preliminary study of diagnostic effectivity on clinical samples of blood serum from patients with COVID-19 and healthy donors showed its high sensitivity and specificity. The new test kit allows to detect IgM to all four structural antigens of SARS-CoV-2 and can be used as a confirmatory test to verify indeterminant screening results in laboratory etiological diagnosis of COVID-19.

At what cycle threshold level are dogs able to detect SARS-CoV-2 in humans?

Dogs can discriminate between people infected with SARS-CoV-2 from those uninfected, although their results vary depending on the settings in which they are exposed to infected individuals or samples of urine, sweat or saliva. This variability likely depends on the viral load of infected people, which may be closely associated with physiological changes in infected patients. Determining this viral load is challenging, and a practical approach is to use the cycle threshold (Ct) value of a RT-qPCR test.

Purpose: We aimed to analyze adolescent and young adults' (AYAs) perspectives on using sexually transmitted infection (STI) self-collection kits to help guide the provision and implementation of accessible and confidential reproductive health-care services for those who experience the burden of STIs and STI-related morbidity.
Methods: We utilized MyVoice, a nationwide text message survey of AYAs, to pose 6 open-ended questions on their perceptions and use of STI self-collection kits. Two independent reviewers used inductive content analysis to develop a codebook and analyze responses, and a third settled any coding discrepancies through discussion to reach consensus.

West Nile Virus (WNV) infection represents a major global public health challenge. Even though most of the patients are asymptomatic, some cases progress to critical condition which may be fatal. Diagnosis traditionally relies on serological methods, but their limitations, including cross-reactivity, highlight the need for alternative approaches.

Background: The risk of onwards HIV transmission is strongly influenced by the interval between HIV infection and its diagnosis. The SELPHI trial examined whether this interval could be reduced by offering free HIV self-testing kits to men-who-have-sex with-men (MSM).
Setting: Internet-based RCT of MSM aged ≥16 years, resident in England/Wales, recruited via sexual and social networking sites.
