Tear antibodies to SARS‐CoV‐2: implications for transmission [PDF]

Clinical & Translational Immunology, 2021
Objectives SARS‐CoV‐2 can be transmitted by aerosols, and the ocular surface may be an important route of transmission. Little is known about protective antibody responses to SARS‐CoV‐2 in tears after infection or vaccination.

Estimation of world seroprevalence of SARS-CoV-2 antibodies. [PDF]

J Appl Stat
In this paper, we estimate the seroprevalence against COVID-19 by country and derive the seroprevalence over the world. To estimate seroprevalence among adults, we use serological surveys (also called the serosurveys) conducted within each country. When the serosurveys are incorporated to estimate world seroprevalence, there are two issues.

Testing for SARS-CoV-2 antibodies [PDF]

BMJ, 2020
### What you need to know As the covid-19 pandemic has unfolded, interest has grown in antibody testing as a way to measure how far the infection has spread and to identify individuals who may be immune.1 Testing also has a clinical role, given the varying symptoms of covid-19 and false negative results of reverse transcription polymerase chain ...

Evolution of antibody immunity to SARS-CoV-2 [PDF]

Nature, 2020
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has infected 78 million individuals and is responsible for over 1.7 million deaths to date. Infection is associated with development of variable levels of antibodies with neutralizing activity that can protect against infection in animal models.

The Antibody Response to SARS-CoV-2 Infection [PDF]

Open Forum Infectious Diseases, 2020
AbstractBackgroundTesting for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–specific antibodies has become an important tool, complementing nucleic acid tests (NATs) for diagnosis and for determining the prevalence of coronavirus disease 2019 (COVID-19) in population serosurveys.

Pre-existing humoral immunity to low pathogenic human coronaviruses exhibits limited cross-reactive antibodies response against SARS-CoV-2 in children

Frontiers in Immunology, 2022
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes asymptomatic or mild symptoms, even rare hospitalization in children. A major concern is whether the pre-existing antibodies induced by low pathogenic human coronaviruses (LPH ...

Absence of SARS‐CoV‐2 RNA and anti‐SARS‐CoV‐2 antibodies in stray cats [PDF]

Transboundary and Emerging Diseases, 2021
AbstractSARS‐CoV‐2 positive or seropositive owned cats have been reported worldwide. The detection of seropositive stray cats in the proximity of farms of infected minks, coupled with the demonstration of cat‐to‐cat transmission in experimental settings, raise the question whether stray cats may have an epidemiological role in the COVID‐19 pandemic and

Circulating anti-SARS-CoV-2 nucleocapsid (N)-protein antibodies and anti-SARS-CoV-2 spike (S)-protein antibodies in an African setting: herd immunity, not there yet!

BMC Research Notes, 2021
Objective Herd immunity is achieved when in a population, immune individuals are in a sufficiently large proportion. Neutralizing antibodies specific to SARS-CoV-2 that are produced following infection or vaccination are critical for controlling the ...
