Polymerase chain reaction (PCR) is a revolutionary laboratory technique that enables the replication of a specific DNA sequence. Using PCR, millions of copies of a target DNA can be easily synthesized within a short period of time.

High antibody and inflammatory mediator levels may predict severe COVID-19

A new study reports on biomarkers could help predict the progression of the viral illness to dangerous levels early enough to enable timely intervention.

More than half of COVID-19 patients report persistent symptoms 12-months after infection

In a new study, appearing on the pre-print server medRxiv*, researchers at the University of Trieste and Istituto Auxologico Italiano IRCCS in Italy report that more than half of patients with previous mild-to-moderate symptomatic COVID-19 complained of the persistence of at least one symptom 12-months after the onset of the illness.

Study demonstrates that the main creators of SARS-CoV-2 mutations are vaccine-suppressed

A new research paper posted to the medRxiv* preprint server describes the changes in genomic sequence observed during the course of infection in a patient on the drug tacrolimus, along with steroids, both potent immunosuppressants, and who also received convalescent plasma treatment. These mutations were observed to occur within three weeks from infection.

No evidence B.1.1.7. variant worsens symptoms or increases risk of long COVID

The study, published in The Lancet, demonstrates that there is no evidence of a link between severe illness and death and lineage when comparing the B.1.1.7 lineage and other variants.

PCR-based reverse genetic system helps analyze SARS-CoV-2 mutations

SARS-CoV-2 is the virus responsible for the COVID-19 pandemic. We know that mutations in the genome of SARS-CoV-2 have occurred and spread, but what effect do those mutations have?

CityMD experience during the coronavirus pandemic in New York City

Limiting SARS-CoV-2 transmission requires an infected person to quarantine themselves for at least two weeks. New research published on the medRxiv* server highlights the vital role urgent care centers play during the COVID-19 pandemic in New York.

Children less likely to spread SARS-CoV-2 than adults

A study conducted by researchers in Canada suggests that children may be less likely than adults to spread the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Real-world evidence from Israel on VOCs and SARS-CoV-2 vaccine protection

A new study by Israeli researchers tested the hypothesis that certain SARS-CoV-2 variants of concern can overcome protection conferred by Pfizer-BioNTech (BNT162b2) mRNA vaccine and found evidence of increased breakthrough rates in vaccinated individuals. The research paper is currently available on the medRxiv preprint server.

New test offers a simpler way to quantify the reservoir of intact viruses in HIV patients

A new test that measures the quantity and quality of inactive HIV viruses in the genes of people living with HIV may eventually give researchers a better idea of what drugs work best at curing the disease.

P681 mutation has little impact on transmissibility in the SARS-CoV-2 UK variant, finds study

A new preprint, recently released on the bioRxiv* server, explores the impact of a single mutation, the P681H mutation, on the transmissibility of the virus.

Study finds no evidence of SARS-CoV2 transmission by breast milk

Some studies have reported the detection of SARS-CoV-2 RNA in breast milk from women who were recently infected with the virus. A new study explores the relationship between viral RNA and infectious virus to clarify the occurrence of vertical transmission through breast milk.

Thermo Fisher Scientific launches in-air SARS-CoV-2 surveillance solution

Thermo Fisher Scientific Inc., the world leader in serving science, today announced the launch of the Thermo Scientific AerosolSense Sampler, a new surveillance solution designed to deliver fast and highly reliable insight into the presence of in-air pathogens, including SARS-CoV-2.

Leaky gut and microbial dysbiosis could contribute to cytokine storm in severely ill COVID-19 cases

The gut is a well-established route of infection and target for viral damage by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent for COVID-19. This is supported by the clinical observation that about half of COVID-19 patients exhibit gastrointestinal (GI) symptoms.

Real-world proof Pfizer and Moderna mRNA vaccines prevent SARS-CoV-2 infection

A new Morbidity and Mortality Weekly Report published by the U.S. Centers for Disease Control and Prevention (CDC) states that mRNA COVID-19 vaccines are highly effective in preventing SARS-CoV-2 infection in the real world. The report is based on a CDC study where it routinely tested prospective cohorts of health care professionals, first responders, and essential and frontline workers for SARS-CoV-2 infections.

New test for Lyme disease can reliably distinguish between early- and late-stage patients

For those who live in an area blighted by ticks, the threat of Lyme disease can cast a shadow over the joy of spring and summer.

Research explores sex differences in placental defenses against SARS-CoV-2 infection

A plethora of earlier studies has reported on the differences between the sexes in susceptibility to the currently circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as its severity. A new preprint research paper posted to the bioRxiv* server extends this to the placenta in pregnancy.

Researchers offer large-scale screening of potential broad-spectrum SARS-CoV-2 antivirals

A new study describes the identification of new compounds from a library, with inhibitory activity against several coronaviruses. This study shows the utility of this method, besides identifying compounds that not only inhibit viral shedding in SARS-CoV-2 cultures, but have an immunomodulatory effect that may be useful in mitigating the damaging cytokine storm typical of severe or critical COVID-19.
