COVID-19 in pregnancy - premature birth common

A new study conducted by researchers at Yonsei University College of Medicine, Korea, suggests that while having coronavirus disease 2019 (COVID-19) during pregnancy has little effect on fetal or neonatal mortality, it can be associated with premature birth and sometimes severe outcomes for mother and baby, including death.

School children unlikely to play a significant role in COVID-19 spread, says Finnish study

A study conducted by researchers in Finland suggests that children who are exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in schools are unlikely to transmit the virus further and play any significant role in the spread of coronavirus disease 2019 (COVID-19).

New simple way of detecting COVID-19 in blood plasma

Even as the COVID-19 pandemic claims increasing numbers of patients, testing numbers are rising in most nations at the leading edge. However, the current reverse transcriptase-polymerase chain reaction (RT PCR) testing is often unavailable and takes up to several days for results to arrive.

Researchers identify targeted treatment strategy for malignant pleural mesothelioma

The reactivation of telomerase is a key mechanism in the unrestricted growth of cancer cells. Malignant pleural mesothelioma (MPM) is a form of cancer originating from the mesothelium, a cell layer covering the lungs and the inside of the chest wall.

Inconsistent SARS-CoV-2 antibody results in nephrology workers

Using a broad spectrum of antibody tests the present study revealed inconsistent results for SARS-CoV-2 seroprevalence among asymptomatic individuals, while this was not the case among Covid-19 patients.

Recurrent SARS-CoV-2 positives not infectious in discharged COVID-19 patients, says Chinese study

A new research paper from China published on the preprint server medRxiv* claims that recurrent positive results for SARS-CoV-2 are due to the presence of low levels of viral RNA fragments and not the shedding of infectious virus particles.

Monthly vaginal ring for HIV prevention receives positive opinion from EMA

The International Partnership for Microbicides today welcomed a positive opinion from the European Medicines Agency on the dapivirine vaginal ring for use by cisgender women ages 18 and older in developing countries to reduce their risk of HIV-1 infection.

Pets show antibodies to SARS-CoV-2 in Italian study

A study shows that reverse transmission of SARS-CoV-2 is probable, with 3-4% of pets showing antibodies to the infection, though no virus was recovered.

Australian researches detect SARS-CoV-2 virus in wastewater from planes and cruise ships

Previous reports have shown that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19), has been found in untreated wastewater. While the data is limited, there are no reported cases of a person becoming infected with the virus due to exposure to contaminated water.

Evidence of SARS-CoV-2 placental infection in mild COVID-19

Now, a new study published on the preprint server medRxiv* in July 2020 reveals evidence of placental infection and hypoxia, despite the lack of serious symptoms in the mother.

Antibodies to SARS-CoV-2 disappear within three months

The question is, does this infection confer lasting immunity? A new study published in the journal Clinical Microbiology and Infection in July 2020 appears to show that it does not, with antibodies to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disappearing within three months of infection.

Saliva promising alternative to upper airway swabs for diagnosis of SARS-CoV-2

The standard diagnostic test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is the reverse transcriptase-polymerase chain reaction (RT-PCR) assay. Now, a new study published on the preprint server medRxiv* in July 2020 describes the use of saliva as a sample in RT-PCR for diagnosis in place of nasopharyngeal or oropharyngeal swabs.

Dutch trial of convalescent plasma in COVID-19 discontinued

Now, a recent trial published on the preprint server medRxiv* in July 2020 reports that a majority of hospitalized COVID-19 patients have a high titer of neutralizing antibodies, at the time of admission, within 10 days of symptomatic disease.

Researchers search for SARS-CoV-2 fomites on an operational Italian bus

A new study reports the results of a viral detection study carried out in buses used for public transport across the final week of lockdown, as travel restrictions were being lifted step by step. This study by Italian researchers and published on the preprint server bioRxiv* in June 2020, may help to understand how a virus can spread within a city bus during normal operation and how effective are the measures used to protect against such transmission.
