What we do and do not know about COVID-19's infectious dose and viral load
(The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts.) (THE CONVERSATION) As the COVID-19 pandemic spreads, it has become clear that people need to understand basic facts about SARS-CoV-2, the virus that causes COVID-19, to make informed health care and public policy decisions. Two basic virological concepts have gotten a lot of attention recently - the "infectious dose" and the "viral load" of SARS-CoV-2.

As the COVID-19 pandemic spreads, it has become clear that people need to understand basic facts about SARS-CoV-2, the virus that causes COVID-19, to make informed health care and public policy decisions. Two basic virological concepts have gotten a lot of attention recently – the “infectious dose” and the “viral load” of SARS-CoV-2. As influenza virologists, these are concepts that we often think about when studying respiratory virus infections and transmission. What is an ‘infectious dose’?
What Are COVID-19's Infectivity and Viral Load?
By Marta Gaglia, Tufts University and Seema Lakdawala, University of Pittsburgh As the COVID-19 pandemic spreads, it has become clear that people need to understand basic facts about SARS-CoV-2, the virus that causes COVID-19, to make informed health care and public policy decisions. Two basic virological concepts have gotten a lot of attention recently – the “infectious dose” and the “viral load” of SARS-CoV-2.
Volcanic carbon dioxide emissions helped trigger Triassic climate change
A new study finds volcanic activity played a direct role in triggering extreme climate change at the end of the Triassic period 201 million year ago, wiping out almost half of all existing species. The amount of carbon dioxide released into the atmosphere from these volcanic eruptions is comparable to the amount of CO2 expected to be produced by all human activity in the 21st century.

Emerging Proviral Roles of Caspases during Lytic Replication of Gammaherpesviruses
ABSTRACTDue to their roles in the regulation of programmed cell death and inflammation, the cellular caspase proteases are considered antiviral factors. However, recent studies have revealed examples of proviral functions for caspases. Here, we review a growing body of literature on the role of caspases in promoting the replication of human gammaherpesviruses.
Caspase-Dependent Suppression of Type I Interferon Signaling Promotes Kaposi's Sarcoma-Associated Herpesvirus Lytic Replication
An important component of lytic infection by Kaposi's sarcoma-associated herpesvirus (KSHV) is the ability of the virus to evade the innate immune response, specifically type I interferon (IFN) responses that are triggered by recognition of viral nucleic acids. Inhibition of type I IFN responses by the virus promotes viral replication. Here, we report that KSHV uses a caspase-dependent mechanism to block type I IFN, in particular IFN-β, responses during lytic infection.
