Covid-19 Analysis and Prediction

What is Data Science?

Data Science is a multi-desciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data.

COVID-19 - Analysis, Viz, Prediction & Comparisons

Corona Virus
Coronaviruses are zoonotic viruses (means transmitted between animals and people).

Symptoms include from fever, cough, respiratory symptoms, and breathing difficulties.
In severe cases, it can cause pneumonia, severe acute respiratory syndrome (SARS), kidney failure and even death. Coronaviruses are also asymptomatic, means a person can be a carrier for the infection but experiences no symptoms

Novel coronavirus (nCoV)

A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.

COVID-19 (Corona Virus Disease 2019)

Caused by a SARS-COV-2 corona virus.

First identified in Wuhan, Hubei, China. Earliest reported symptoms reported in November 2019.
First cases were linked to contact with the Huanan Seafood Wholesale Market, which sold live animals.

On 30 January the WHO declared the outbreak to be a Public Health Emergency of International Concern

Processing

Cleaning Data

# cases
cases = ['Confirmed', 'Deaths', 'Recovered', 'Active']

# Active Case = confirmed - deaths - recovered
full_table['Active'] = full_table['Confirmed'] - full_table['Deaths'] - full_table['Recovered']

# replacing Mainland china with just China

# filling missing values
full_table[['Province/State']] = full_table[['Province/State']].fillna('')
full_table[cases] = full_table[cases].fillna(0)

Derived Tables

# cases in the ships

# china and the row
