Literature Survey: Computational Models for Analyzing and Predicting the Spread of the Coronavirus Pandemic

Viral diseases are extremely widespread infections caused by viruses, which is a type of microorganism. Some of the common curable viral diseases are common cold, flu, pneumonia mumps, measles, etc. In addition to this, there are also some deadly viral diseases are human immunodeficiency virus (HIV), human pappilomavirus (HPV), SARS, Ebola, etc., which is incurable. The recent coronavirus has also taken its place in this latter list for which the vaccine is yet to be discovered. As early diagnosis is the only option as of now which could control the death rate of this disease, several researchers are in the process of inventing drugs and vaccines for the same. At this stage, it is vital to develop some automated systems that could possibly detect the virus’s presence at an early stage. Numerous scholarly articles concerning proposing computational models encompassing the spread of the coronavirus disease have been studied, analyzed, and juxtaposed with an aim to determine the optimality and accuracy of various models. This work aims to develop a collective study on the models developed so far for the prediction and spread of coronavirus. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

COVID-19 highlights the need for servicer access to a government-backed liquidity facility

The fundamental differences between the structure of the market for government mortgages, pooled into Ginnie Mae securities, and the market for government sponsored enterprises (GSE) mortgages are at the heart of the constraints that impact the servicing of government loans. This is exacerbated by the higher-risk profile of Ginnie Mae borrowers and heavy concentration of non-banks in the Ginnie space. The pandemic and the subsequent passage of the CARES Act demonstrated the need for a federal liquidity facility for non-banks. This is a more pressing issue in the Ginnie Mae market, with potential systemic implications for the mortgage market. This article explains these issues in detail, concludes that a federal liquidity for non-banks is necessary, and discusses two options, one for the current crisis and another for the future: a COVID-19 liquidity facility at the Federal Reserve, and in the long run, federal home loan Bank (FHLB) membership for non-banks to allow for access to FHLB advances.
