Introduction
On 10th of January 2020, Chinese health offcials reported 41 cases
of pneumonia due to a novel corona virus (2019-nCoV), including
seven patients with severe illness and one death. Symptoms have
included fever, cough, and diffculty breathing.

The earliest diagnosis
date for a case identifed in China is 08 December 2019. Preliminary
analysis of viral genomes from China and other countries suggests
that initial transmission from a zoonotic reservoir to humans could
have occurred as early as late October. The frst cases reported had
links to a seafood and live animal market in Wuhan, China, suggesting
infection of humans from an animal source.

Health authorities in
China have limited transportation in and out of heavily affected cities
and are continuing to monitor close contacts, including health care
workers, for illness. Several territories in Asia and countries across
the globe are screening incoming travelers from Wuhan. Corona
viruses (COVID-19) are large family of viruses. There are several
known human corona viruses that usually only cause mild respiratory
disease, such as the common cold. However, at least twice previously,
corona viruses have emerged to infect people and cause severe
disease: severe acute respiratory syndrome (SARS) and Middle
East respiratory syndrome (MERS).

The cases in this outbreak
tested negative for both SARS and MERS. Clinical characteristics of
infection, such as incubation period, have not yet been determined.
Based on the incubation period of SARS and MERS, signs of 2019-
nCoV could appear from 2-14 days after exposure. Human to human
transmission has been documented, and healthcare workers have been
infected. Like other corona viruses, people may be infectious before
showing any symptoms of the disease.

As of 9 am, 14 April 2020, a total of 15,284 COVID-19 cases and
816 (CFR: 5%) deaths have been reported in 52 African countries. Out
of 52 Member States that have reported cases, six have community
transmission, 44 have local transmission and two have imported cases
only. Since the last brief, the number of COVID-19 cases has increased
by 52% (5,198 cases). The fve countries in Africa with the highest
cumulative number of cases (proportion of reported cases in Africa) are
South Africa (2,272; 15%), Egypt (2,190; 14%) Algeria(1,914; 13%),
Morocco (1,763; 12%) and Cameroon (820; 5%). When population is
taken into consideration, Djibouti (30.2), Mauritius (25.5), Seychelles
(11.2), Tunisia (6.1), and Morocco (4.8) are reporting the most cases
per 100,000 population within the continent. Fifteen countries are
reporting case fatality rates higher than the global case fatality rate
of 6%. See Figure 1 for the full list of countries in Africa reporting
cases, deaths, and COVID-19 recoveries in addition to transmission
type being reported. Africa CDC is working with all affected countries
and is mobilizing laboratory, surveillance, and other response support
where requested.

Abstract
This study is a monitoring analysis of COVID-19 in Africa. The data used for the study
is sourced from the Africa Centre for disease Control (Africa CDC) as t 10:00PM on the
24th of April, 2020 which comprises number of Africa countries with laboratory confrmed
cases, number of death and number of discharged/recovered cases. The quality pandemic
monitoring/control tools used in this study is fsh-bone diagram, Pareto analysis, control
chart, bar chart and pie chart. The fsh bone diagram depicts the likely symptoms to check
out for in a patent infected by COVID-19; the Pareto analysis shows that 14 countries
to the left of this line (South Africa, Egypt, Morocco, Algeria, Cameroon, Ghana, Ivory
Coast, Djibouti, Tunisia, Nigeria, Guinea, Niger and Burkina Faso) constitute 80% of all
the infected countries; the trend analysis shows that the spread of the pandemic is still on
an increase rate; and lastly, from the performance assessment, it is seen that the pandemic is
still under control from the pie chart while the death rate is already out of control.
