Coronavirus age

We [Riou et al ] estimated the age-specific case fatality ratio (CFR) by fitting a transmission model to data from China accounting for underreporting of cases and the time delay to death We find that 1 6% (1 4-1 8) of individuals infected with COVID-19 [in Hubei between 1 Jan and 11 Feb] with or without symptoms died or will die with even more important differences by age group than

Hot Humid Weather Slows SARS

For the SARS-CoV-2 virus the reproduction number is 2 to 3 "If we lower the reproduction number by 30% there's a chance of getting it to 1 or lower (for influenza) which is the threshold for controlling it For COVID-19 a 30% reduction likely wouldn't bring the reproduction number to 1 " Rahmandad said

The role of environmental factors to transmission of SARS

The current outbreak of the novel coronavirus disease 2019 (COVID-19) in more than 250 countries has become a serious threat to the health of people around the world Human-to-human transmission of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurs most often when people are in the incubation stage of the disease or are carriers and have no symptoms

Asymptomatic spread of SARS

A report released by the U S Centers for Disease Control and Prevention (CDC) revealed the occurrence of presymptomatic transmission of SARS-CoV-2 The study shows the investigation of 243 cases of COVID-19 in Singapore between January 23 and March 16 revealing that seven clusters of cases point to presymptomatic transmission as the reason for secondary cases

Human Immunodeficiency Virus (HIV) Infection

Transmission of HIV requires contact with body fluids—specifically blood semen vaginal secretions breast milk saliva or exudates from wounds or skin and mucosal lesions—that contain free HIV virions or infected cells Transmission is more likely with the high levels of virions that are typical during primary infection even when such infections are asymptomatic Transmission by saliva

10 Johnson found that masks reduced respiratory transmission of influenza virus a disease commonly used as a model for SARS-CoV-2 (3) In this context Bae's null hypothesis that masks do not reduce viral load transmission was inappropriate Combined with Bae's small sample size this led to reporting of mask wearing causing no significant reduction in SARS-CoV-2 viral load transmission

Transmission of SARS

• Transmission of SARS -CoV-2 is most strongly associated with close and prolonged contact the amount of time spent in close proximity to the infectious person and with the reduction of distance A calculation based on [3] suggests risk at 2m face-to-face is around 10 times lower than the risk at 1m A new meta -analysis paper of reported transmission suggests that the risk of
