COVID-19 Rise and Spread with Specific Predictions till 1st April for India and US

March 28, 2020 0 comments

1. Background

The number of confirmed novel coronavirus cases in India has reached close to 750 cases as of 27th March 2020.  According to the health ministry, Covid-19, which has globally infected over 1.5 lakh people, is likely to cause more shutdowns across the country as more states rush to stop the virus from spreading. While 13 people who were infected by the virus have recovered in India, the global situation still paints a grim picture. The death toll due to new coronavirus has shot up sharply in Italy, which has now become the country worst affected by the virus outbreak after China. Now US cases have also risen drastically. Besides taking precautions to prevent the spread of the virus domestically, India is also actively rescuing its nationals stuck in the high-affected zone as well as trying to help its neighbours in this warlike effort.

The WHO, Governments of the world have made open source several datasets related to COVID-19 for the Scientific community to study, analyse and may be come up with possible measures to prevent or stop the spread of the same


2. The objective of the current study

In this study, we compare the rise of COVID Cases for India and US with a few selected countries. We further aim to compare the spread of COVID-19 in India and US and tries to predict the possible cases until 1st April using data up to 25th March.  We try to see how using a very simple univariate data available from John Hopkins University how accurately one can predict e rise with simple mathematical modelling.

Fitting 3rd Degree polynomial to predict US COVID-19 RISE

7. Mathematical Modelling Approach

In order to predict the COVID-19 rise for India and US, A simple but effective curve fitting has been employed.  The univariate public source data is filtered to create a numeric series starting from the day where 100 cases or more have been reached.  That as our start point we then fit a 3rd-degree polynomial till the data up to 25th March.  Once we have our polynomial we then use it to predict a forward-looking window of 7 days, in this case till 1st April.   Special comparison for Lockdown as in India has not been modelled.


8. Conclusions

With experts, the world over trying to come up with sophisticated models to predict COVID-19 rise quickly, this paper attempts to address the problem using a very simple numerical methods approach based on near history.   The results look promising for the immediate future. As lockdowns start taking shape and the weather changes as well more sophisticated models have to employed going hence to reach accurate levels of prediction specially for large countries like US and India
