The number of coronavirus infections has hit 16.41 million worldwide, while more than 652,000 people have died and more than 10 million patients have recovered from the virus.
The US has by far the largest coronavirus outbreak in the world, with 4, 3 million cases testing positive for the virus. However research suggests that its 4 million reported infections are a small fraction of the true case total. Florida has overtaken New York in the number of coronavirus cases, according to the latest figures from the health department.
Brazil’s health ministry reported 23,467newly confirmed Covid-19 cases, bringing the country’s total to 2,419,901. The ministry also reported 556 new deaths from the virus, bringing Brazil’s death toll to 87,052.
China reported 61 new confirmed cases of coronavirus, spread between its northeastern and northwestern regions. It is the highest daily tally of new virus cases since April 14, when 89 cases, mostly imported, were recorded. No new deaths were reported, leaving the toll from COVID-19 in the country at 4,634 among 83,891 cases.
North Korea has reported its first suspected case of Covid-19.
South Africa’s health ministry reported 11,233 new cases of the coronavirus, bringing the country’s total confirmed case count to 445,433. The number of people who have officially died from coronavirus in the country is 6,769. There have been 256 077 recoveries which is a 60% recovery rate.
7, 529 positive cases have been recorded in the mining sector. 70 deaths have been recorded with 37 of them from the PGMs sector.
Last week, officials from the World Health Organization expressed concern the country’s rising numbers could signal greater Covid-19 spread throughout Africa. South Africa has the highest number of confirmed cases in Africa and the fifth highest number worldwide, following the United States, Brazil, India and Russia.
Zambia second to South Africa has the second highest number of cases in Southern Africa as 4,481 confirmed cases have been recorded in the country. 153 new cases were recorded yesterday and the current death toll now stands at 139 fatalities.
78 new cases were recorded in Zimbabwe to bring the total cases to 2,512.of the 78 cases reported, 74 cases were local cases and 4 were imported cases from South Africa. No new positive cases were recorded in Harare although the city remains the epicenter of the disease. No new death was recorded yesterday hence the death toll remains at 34.
86 new cases were recorded in Lesotho and the total number now stands at 505. 3 new deaths were recorded to bring the total number of fatalities to 12.
Covid-19-infected droplets spread further in cold, humid climates
Scientists have found a new way of modelling the Covid-19 spread via airborne respiratory droplets. Generally acknowledged as the main means of transmission for the coronavirus, respiratory droplets spread via talking, sneezing, coughing and singing. They contain small bits of proteins and pathogens that can be passed on to others if they inhale the droplets or touch infected surfaces. A human can exhale droplets between 1 to 2 000 micrometres, which is why it’s so important to know what the evaporation rate of the droplets is.
New mathematical model
Researchers developed a multi-scale model that connects the infection dynamics of the pandemic and the real physics of droplets to measure the role that environmental factors play in the spread of the coronavirus via respiratory droplets.
Environment plays a factor
At 35 degrees Celsius and 40% humidity, a droplet could travel around 2.5 metres, but at five degrees Celsius and 80% humidity, the droplet’s travel distance increases to 3.6 metres. Droplets are far more likely to evaporate faster in the absence of a surface contact, and while smaller droplets can evaporate in a fraction of a second, when they form a cloud they linger longer and are much more likely to infect another person. Bigger droplets have a bigger chance of falling to a surface before evaporating into the air. Other factors also include the force by which the droplets are expelled, and how fast they decelerate due to lack of momentum.
While WHO officials do not deny airborne spread, they reiterate that more research and definitive evidence is needed to confirm it as a major mode of transmission
