Countries around the world are scrambling to halt the spread of the coronavirus pandemic.

As of July 30, more than 667,000 people worldwide have died of COVID-19, the highly infectious respiratory disease caused by the coronavirus.

The number of people who have tested positive for COVID-19 has reached over 17 million, according to data compiled by Johns Hopkins University. Nearly 10 million people have recovered.

Here is what you need to know:

What is a coronavirus?

According to the World Health Organization (WHO), coronaviruses are a family of viruses that cause illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS).

These viruses were originally transmitted from animals to people. SARS, for instance, was transmitted from civet cats to humans while MERS moved to humans from a type of camel.

Several known coronaviruses are circulating in animals that have not yet infected humans.

The name coronavirus comes from the Latin word corona, meaning crown or halo. Under an electron microscope, the virus looks like it is surrounded by a solar corona.

The novel coronavirus, identified by Chinese authorities on January 7 and since named SARS-CoV-2, is a new strain that had not been previously identified in humans. Little is known about it, although human-to-human transmission has been confirmed.

What are the symptoms?

According to the WHO, signs of infection include fever, cough, shortness of breath and breathing difficulties. Other signs include loss of taste or smell as well as muscle aches.

In more severe cases, it can lead to pneumonia, multiple organ failure and even death.

Current estimates of the incubation period – the time between infection and the onset of symptoms – range from one to 14 days. Most infected people show symptoms within five to six days.

However, infected patients can also be asymptomatic, meaning they do not display any symptoms despite having the virus in their systems.

How deadly is it?

The number of fatalities from the new coronavirus has overwhelmingly surpassed the toll of the 2002-2003 SARS outbreak, which also originated in China.

SARS killed about 9 percent of those it infected – nearly 800 people worldwide and more than 300 in China alone. MERS, which did not spread as widely, was more deadly, killing one-third of those infected.

While the new coronavirus is more widespread than SARS in terms of case numbers, the mortality rate remains considerably lower at approximately 3.4 percent, according to the WHO.

According to the Centers for Disease Control and Prevention (CDC), older people are at higher risk for severe illness from COVID-19 which may result in increased stress during a crisis.

People who have severe underlying medical conditions like heart or lung disease or diabetes also seem to be at high risk for developing more serious complications from COVID-19 illness.

Where have cases been reported?

Since March 16, more cases were registered outside mainland China than inside, marking a new milestone in the spread of the global pandemic. 

The virus has spread from China all around the world, prompting the WHO to label the COVID-19 outbreak a pandemic.

Human-to-human transmissions became evident after cases were recorded with no apparent link to China.

What is being done to stop it from spreading?

Scientists around the globe are racing to develop a vaccine but have warned it is not likely one will be available for mass distribution before 2021.

Meanwhile, a growing number of countries have introduced a series of sweeping measures to slow the spread of the coronavirus, including nationwide lockdowns, bans on gatherings, closure of schools, restaurants, bars and sports clubs, as well as issuing mandatory work-from-home decrees.  

International airlines have cancelled flights the world over. Some countries have banned non-citizens from entering their territories, and several more have evacuated their citizens from abroad.

Where did the virus originate?

Chinese health authorities are still trying to determine the origin of the virus, which they say likely came from a seafood market in Wuhan, China where wildlife was also traded illegally.

On February 7, Chinese researchers said the virus could have spread from an infected animal species to humans through illegally-trafficked pangolins, which are prized in Asia for food and medicine.

Scientists have pointed to either bats or snakes as possible sources of the virus.

Is this a global emergency?

Yes, this outbreak is a global health emergency, the WHO said on January 30, raising the alarm further on March 11 when it declared the crisis a pandemic.

The international health alert is a call to countries around the world to coordinate their response under the guidance of the WHO.

There have been five global health emergencies since 2005 when the declaration was formalised: swine flu in 2009, polio in 2014, Ebola in 2014, Zika in 2016 and Ebola again in 2019.

Are smokers more likely to be at risk from coronavirus?

Smoking can make people more susceptible to serious complications from a coronavirus infection, the European Union agency for disease control said.

In its updated assessment of the risks caused by the coronavirus, the European Centre for Disease Control and Prevention (ECDC) included smokers among those potentially most vulnerable to COVID-19.

Smokers have also appeared to be more susceptible to breathing complications caused by the disease, and the ECDC said it was advisable to identify them as a potential vulnerable group, confirming an earlier assessment.

The agency cited a study by Chinese doctors which on a sample of 99 patients affected by the coronavirus found that acute smokers were more at risk of dying than elderly people.

The ECDC report also said smoking was associated with heightened activity in the lungs of an enzyme, ACE2, that could make patients more vulnerable to COVID-19, citing a study conducted by Guoshuai Cai, from the University of South Carolina.

The activity of ACE2, or angiotensin-converting enzyme 2, also increases with age and with some kinds of hypertension treatment – both risk factors – the ECDC said.

Muntu Blocked in Kamwenge

Published

Alliance for National Transformation presidential candidate Gen. Mugisha Muntu has been blocked from campaigning in Kamwenge according to a statement he released earlier today.Below is the full statement:

STATEMENT
Today in Kamwenge, as we have done since the start of the campaign season, we headed out to speak with the people. We had earlier in the week agreed on the venue with security agencies. No one had anticipated that it would rain as much as it did, making it impossible for us or the people to access.

After identifying an alternative place only 100m away from the original venue, negotiating with the owner and communicating the same to the public, we headed to the second venue only to be stopped by police.

Our policy has always been to do all we can to be reasonable, even in the face of unreasonable action on the part of the state. We engaged the police leadership in a civilized, respectable manner well knowing that they intended to not only frustrate us, but cause us to act in ways that would give them an excuse to cause chaos. This was on top of their intimidating the radio we had booked and duly paid to appear on.

While we are confident that we are on the right side of both the law and reason, we have chosen not to endanger the lives of our supporters or the general public by escalating the situation. We will do everything humanly possible to avoid a single life being lost or blood being shed on account of our campaign.

And yet this truth remains: the regime’s days are numbered.
