Case Reports
A Case of a Malignant Lymphoma Patient Persistently Infected with SARS-CoV-2 for More than 6 Months.
Coronavirus disease 2019 (COVID-19) is an emerging infectious disease caused by severe acute respiratory syndrome 2 (SARS-CoV-2). There are many unknowns regarding the handling of long-term SARS-CoV-2 infections in immunocompromised patients. Here, we describe the lethal disease course in a SARS-CoV-2-infected patient during Bruton's tyrosine kinase inhibitor therapy. ⋯ SARS-CoV-2 whole-viral sequencing revealed that the patient shed the virus long-term. Viral infectivity studies confirmed infectious virus on day 189, suggesting that the patient might be still infectious. This case report describes the duration and viral genetic evaluation of a patient with malignant lymphoma who developed SARS-CoV-2 infection during Bruton's tyrosine kinase inhibitor therapy and in whom the infection persisted for over 6 months.

Cutaneous abnormalities were among the first clinical findings reported in patients infected with SARS-CoV-2 at the onset of the COVID-19 pandemic, but the significance was initially unclear. Correlations have since been drawn between many of these cutaneous eruptions and their diagnostic or prognostic value. Additionally, COVID-19 vaccines have generated acute and delayed cutaneous reactions with which clinicians should be familiar. In this narrative review, we update the cutaneous abnormalities associated with COVID-19 infection for pediatric and non-White populations, and common cutaneous reactions to COVID-19 vaccines.

Following a COVID-19 mass vaccination campaign, it is important to evaluate the population level of SARS-CoV-2 antibodies. The aim of this study was to estimate the seroprevalence rate of SARS-CoV-2 specific antibodies acquired due to infection or vaccination in the Portuguese population. ⋯ There was a significant increase in SARS-CoV-2 seroprevalence following the mass vaccination campaign in Portugal. It is important to continue to monitor the distribution of specific SARS-COV-2 antibody at the population level to further inform public health policies.

Vaccine Effect on Household Transmission of Omicron and Delta SARS-CoV-2 Variants.
We evaluated the household secondary attack rate (SAR) of the omicron and delta severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants, according to the vaccination status of the index case and household contacts; further, in vaccinated index cases, we evaluated the effect of the antibody levels on household transmission. ⋯ Immunisation of household members may help to mitigate the current pandemic.

A machine learning algorithm identifies four reproducible clinical subphenotypes of long COVID from the electronic health records of patients with post-acute sequelae of SARS-CoV-2 infection within 30–180 days of infection; these patterns have implications for the treatment and management of long COVID.
