The authorities in northwest Nigeria’s Kano and Jigawa states say a cholera outbreak has killed about 300 people.

Nigeria experiences annual cholera outbreaks during the rainy season but this year’s death toll appears to be higher than in previous years.

Overall, Nigeria’s Centre for Disease Control says the cholera outbreak has hit more than half of the country’s 36 states.

Thousands of people have been infected and hundreds have died - with most of the victims being children.

The north of Nigeria has seen the highest number of cases.

The outbreak started in March but worsened in recent weeks.

It is coinciding with a significant upsurge in Covid-19 cases and a doctors' strike by doctors.

With the entire health system under strain, the authorities are struggling to stop the spread of cholera.
