TB: Taxis’ deadly passengerCar accidents cause a significant number of deaths in SA.

Millions of South Africans rely on minibus taxis daily, but South Africa’s most widely used mode of public transport could also be ferrying a deadly passenger.

About a 100 members of the AIDS lobby group the Treatment Action Campaign (TAC) recently took to some of Johannesburg’s busiest taxi ranks to spread awareness about tuberculosis (TB). Dodging and weaving among the queues of passengers at the Bree, Noord and Wanders street taxi ranks, activists had one simple message: Open a window and stop TB.

TB remains the leading cause of death in South Africa and accounted for almost nine percent of all deaths reported in Statistics South Africa’s latest report on causes of death in the country.

TB is spread after bacteria become airborne after those living with the bacteria cough, sneeze or even speak. With minibus passengers squeezed tightly into taxis with about 19 other people, it is not hard to see why a 2013 study found that taxis carried the greatest TB risk among public transport means.

Published in the American Journal of Epidemiology, the study tracked the amount of carbon dioxide – the gas exhaled by humans – on commutes made by minibus taxi, bus or train. Researchers then used mathematical modelling to predict commuters’ TB risk by mode of transport and found that the risk was highest among taxi users. Poor ventilation in taxis meant that minibus commuters faced a five percent annual risk of contracting TB, according to the research.

About 70 percent of South African households use minibus taxis, according to Statistics South Africa’s 2013 National Household Travel Survey.

TB talking points

At TAC’s recent awareness-raising drive, many taxi drivers reported that they had not previously been aware of the risks.

“It is a good move that TAC, as an organisation, is actually doing this because many people do not have enough information,” said taxi driver Sibongiseni Mngomezulu who works out of the Noord taxi rank in Johannesburg’s inner city. “Sometimes people are ignorant to such an extent that they find themselves getting sick when that could be prevented.”

“As taxi drivers, we appreciate what TAC did because even we did not understand why is it so important to tell passengers to open windows,” he told OurHealth.[quote float= right]”As taxi drivers, we appreciate what TAC did because even we did not understand why is it so important to tell passengers to open windows”

Mngomezulu’s co-worker Mfanafuthi Zwane said that the stickers were a conversation starter. He added that he planned to use the stickers to introduce the topic of TB awareness among his passengers.

Fellow driver Sizwe Ngubane urged the TAC to work closely with taxi associations to promote public health messaging at high-traffic ranks.

“It is a good idea to distribute these stickers so that even us passengers we will be able to see them and do what is right for us,” said passenger Ntombi Moremi. ”As South Africans, we are still fortunate that there are organisations like TAC that give health education through taxi ranks where there are people.”

According to TAC Gauteng Secretary Godfrey Lebono, the country’s largest member-based HIV organisation plans to work more closely with Gauteng taxi associations.

Construction worker Mxolisi Mtolo added that he thought government needed to do more to bring health services like TB testing into spaces like taxi ranks.

“We need mobile clinics all over that will be bring health services near to people,” said Mtolo, who added that visiting a formal clinic often means he loses a day’s pay. “That will actually help a lot to avoid long queues.”

“It would be easy to take my lunch time to rush to the mobile clinic and be able to test for all sickness such as TB, HIV and others,” he added.

The march comes on the heels of Deputy President Cyril Ramaphosa’s 24 March launch of a national TB screening campaign. According to Ramaphosa, the campaign is expected to be the largest ever conducted in South Africa. According to Ramaphosa, at least 140,000 people have already been screened for TB as part of the campaign.
