Sleeping sickness hits new low

The tsetse fly.

For the first time in half a century, the number of new diagnosed cases of human African trypanosomiasis -also known as sleeping sickness - has dropped below 10,000 thanks to partnerships with drug companies and improved screening, according to the UN World Health Organization (WHO).

The parasite, spread by infected tsetse flies mostly found in rural sub-Saharan Africa, can invade a person’s central nervous system and lead to psychiatric and sleep disorders, and if untreated, death. Because of under-reporting, estimates of the actual number of infections range from tens of thousands to hundreds of thousands.

In 2009, there were 9,877 new reported cases compared with 17,600 in 2004 and 38,000 in 1998. “The historic drop in cases is the result of improved and persistent field activities and of active systematic screening,” Pere Simarro, head of WHO’s Human African Trypanosomiasis Programme, told IRIN. More health centres in 36 endemic sub-Saharan countries are diagnosing the disease.

Though 72 percent more people were tested from 2000-2009 than during the previous decade, scientists say lack of low-tech, rapid testing and safe drugs has prevented the elimination of the disease. The highest number of cases were reported in Democratic Republic of Congo (80 percent), followed by Central African Republic (11 percent).

Right now, we’re working with contributors on the ground in Ukraine and in neighbouring countries to tell the stories of people enduring and responding to a rapidly evolving humanitarian crisis.

We’re documenting the threats to humanitarian response in the country and providing a platform for those bearing the brunt of the invasion. Our goal is to bring you the truth at a time when disinformation is rampant. 

But while much of the world’s focus may be on Ukraine, we are continuing our reporting on myriad other humanitarian disasters – from Haiti to the Sahel to Afghanistan to Myanmar. We’ve been covering humanitarian crises for more than 25 years, and our journalism has always been free, accessible for all, and – most importantly – balanced. 

You can support our journalism from just $5 a month, and every contribution will go towards our mission.
