Hit by HIV, South Africa Deploys WhatsApp to Fight Virus
(Bloomberg) -- About two weeks ago Praekelt.org, a non-profit foundation that runs a WhatsApp service on maternal wellbeing for South Africa’s Health Department, proposed setting up a similar program to keep people informed about the coronavirus.
After a team from the department and the National Institute for Communicable Diseases provided the content and with help from WhatsApp, the service launched on March 4. It now has two million users in South Africa and about 100,000 inquiries an hour.
“In a time of pandemic you have to make decisions really quickly,” said Gustav Praekelt, the 49-year-old founder who started and ran a company that set up information services for mobile-phone companies and banks.
While the coronavirus was slow to arrive in South Africa, cases are gathering pace with at least 402 people infected. The government acted quickly by closing schools, restricting travel and banning large gatherings.
With the largest number of people with HIV in the world and widespread tuberculosis, it has reasons to be concerned.
The WhatsApp service is just one example of the actions taken ahead of an expected surge in the disease. It’s simple -- just type ‘Hi’ to the number and you are offered a menu, and then artificial intelligence gives instant information on the latest news about the virus, where to get treatment, symptoms and scams.
People infected with HIV, which damages immune systems and causes AIDS, are more likely to die if they contract Covid-19, according to the assumptions of medical professionals. People with HIV make up a large proportion of the 300,000 South Africans with tuberculosis, a disease that diminishes lung capacity.
In addition, there are gold miners with lungs shredded by silica shards and those in poor respiratory health due to pollution from coal-burning power plants in the east of the country. All of these add to the burden the health system will face. Extreme poverty, and the attendant problems with sanitation leave many at risk, while high obesity levels have boosted the number of diabetes sufferers.
“We have a large population that’s vulnerable due to their health status,” said Atiya Mosam, a public-health specialist at Johannesburg’s University of the Witwatersrand. “Our uniqueness is really the high burden of diseases such as TB and HIV as well as being one of the most unequal societies in the world, which could cause a large and quick spread of the disease.”
That’s both a threat and an advantage in the coming battle: South Africa’s health system is used to dealing with epidemics. The high number of people with tuberculosis, for instance, has given health professionals experience with contact tracing and isolation wards.
“At multiple levels we have epidemic preparedness in place,” said Salim Abdool Karim, director of the Centre for the AIDS Program of Research in South Africa and a professor of Global Health at New York’s Columbia University. “We are quite well placed as a country to take this on.”
The country has as many as 7.8 million people infected with HIV, including 2.5 million who aren’t taking anti-retroviral treatment and about half a million with very weak immune systems, said Karim, whose organization is funded by the European Union and the U.S. and South African governments.
Preparations for a spike in demand for acute medical care are underway, even though they’re complicated by the fact that the bulk of resources are in the private sector.
Of the nation’s almost 60 million people, about 16% have private insurance. They’re served by 70% of the nation’s doctors and consume almost half the spending on medical care, according to the health department.
Private hospitals are taking in some of the coronavirus sufferers from state hospitals. The three biggest companies -- Mediclinic International Plc, Netcare Ltd. and Life Healthcare Group Holdings Ltd. -- are in talks with the government about providing assistance. Aspen Pharmacare Holdings Ltd., a drugmaker, is prioritizing production lines such as antibiotics and anesthetics to ease the burden a wider outbreak may bring.
While the public sector has about 800 intensive care unit beds, according to Mosam, Life Healthcare alone has 8,225 acute-care beds in 49 hospitals, according to Charl van Loggerenberg, the company’s general manager of emergency medicine.
Mining companies have also offered the use of their hospitals for members of the general public affected with the coronavirus.
Beds are being cleared and some elective surgery is being put off, according to Karim. The government has the capacity to test 5,000 people a day and will ramp that up to 30,000 by mid-April, said Zweli Mkhize, the health minister. Quarantine centers are being set up.
The country’s preparedness has been noted.
The World Health Organization noticed Praekelt’s service and on Friday launched it in English on WhatsApp with a Swiss number. Other languages will follow.
It already has 8.5 million users, said Praekelt.
