Cyclone Idai

Tropical Cyclone Idai has caused huge deaths and economic losses in Mozambique, Malawi, Zimbabwe, and South Africa. Cyclone Idai made landfall on Mozambique and later moved in a westerly direction. Idai is the deadliest Tropical cyclone witnessed in 2019.

Idai originated from a tropical depression that formed off the eastern coast of Mozambique and made landfall in Mozambique. The depression later reemerged into the Mozambique Channel and was upgraded into Moderate Tropical Storm.

Tropical Cyclone

Tropical Cyclone is an intense low-pressure area or a whirl in the atmosphere over tropical or sub-tropical waters, with organised convection, circulating either anti-clockwise (in the northern hemisphere) or clockwise (in the southern hemisphere).

Conditions which favour Tropical Cyclone Formation
  • A source of warm, moist air derived from tropical oceans with sea surface temperature normally near to or in excess of 27 °C
  • Winds near the ocean surface blowing from different directions converging and causing air to rise and storm clouds to form
  • Winds which do not vary greatly with height known as low wind shear. This allows the storm clouds to rise vertically to high levels.
  • Coriolis force/spin induced by the rotation of the Earth. The formation mechanisms vary across the world, but once a cluster of storm clouds starts to rotate, it becomes a tropical depression. If it continues to develop it becomes a tropical storm, and later a cyclone/ super cyclone.

Pressure increases outwards from the centre of a cyclonic storm. The amount of the pressure drop in the centre and the rate at which it increases outwards gives the intensity of the cyclones and the strength of winds.

First malaria vaccine to be tested in Kenya, Ghana and Malawi in 2018

The World Health Organization has announced that it is ready to test the first malaria vaccine in the real world setting in 2018. The aim of the testing will be to ascertain whether the vaccine will work under real world circumstances or not. Kenya, Ghana and Malawi have been chosen for taking part in the pilot project.

The vaccine, RTS,S, also known as Mosquirix, was produced by GlaxoSmithKline in 1987 in a public-private partnership with the PATH Malaria Initiative and with support from the Bill and Melinda Gates Foundation. In 2015, the vaccine received approval from the European Medicines Agency (EMA).

For the next four years (2017-2021), the vaccine will be administered to children between 5 and 17 months in Kenya, Ghana and Malawi. The vaccine will be given four times and will be administered by an intramuscular injection.

The RTS, S vaccine works by targeting the liver phase of the malaria parasite’s life cycle as the parasite multiplies inside the liver after getting introduced into the body by a mosquito bite. It has taken about 30 years for the creation of the vaccine to the approval of pilot programme in 2017. Only five species of Plasmodium parasite spread malarial parasite worldwide.


According to WHO, malaria kills one child every two minutes and has killed 429,000 people in 2015. According to the WHO World Malaria Report 2016, Nigeria suffers most malaria deaths worldwide (26%), followed by the Democratic Republic of Congo (10%), India (6%), and Mali (5%). African continent suffers the most mosquito-borne ailments and there still exists gaps in prevention coverage as many people in sub-Saharan Africa lack access to mosquito protection like bed nets or bug spray.
