Malaria Treatment Statistics

by

QUESTION

Where can I find information on the ratio of malaria cases treated annually globally or per country?

ANSWER

A great resource for information on malaria is the World Health Organisation (WHO). They publish an annual malaria report which also includes lots of statistics about numbers of cases, numbers treated, and numbers of deaths from malaria. Some of the data is even available at the country level, I believe. You can download these reports, and also find out a lot more information about malaria, at the World Health Organisation malaria page.

Malaria Cases in West Bengal

QUESTION:

What is the number of Malaria patients in West Bengal?

ANSWER:

West Bengal is one of the states considered highly endemic for malaria in India. In 1998, cases in West Bengal comprised approximately 6% of the total number of cases of all malaria in India (corresponding to 129,000 of the total 2.15 million cases reported that year), and approximately 3% of the cases of Plasmodium falciparum malaria, the most acute and deadly form of the disease. However, more recently, there are encouraging signs of decreasing mortality from malaria in West Bengal; in 2007, the number of reported deaths from malaria was 100, down from 203 in 2006 (the total number of cases in 2007 was estimated at 86,132).

Malaria Statistics

QUESTION:

What are the statistics of malaria?

ANSWER:

If you mean the number of cases worldwide and the number of deaths, then the statistics are as follows: the World Health Organization estimates that approximately half the world’s population are at risk from malaria infection, and as a result, there are somewhere between 300 and 500 million cases of malaria every year, worldwide.

However, this may be an underestimate, since many people don’t seek help when they have malarial symptoms. The same is true of number of deaths per year from malaria – it is currently estimated that between 700,000 and 800,000 people die every year from the disease, but as with the number of cases, there may be unreported deaths as well. Organisations such as Malaria No More seek to eliminate deaths from malaria by the year 2015.

Incidence of malaria in Quito, Ecuador

by

QUESTION:

What is the number of cases of malaria reported in Quito, Ecuador? In 1940 was it a common problem?

ANSWER:

There is no transmission of malaria in Quito – it is at too high an altitude! Transmission of malaria in Ecuador is estimated to stop at around 1500m of altitude, and the central plaza of Quito, Plaza Grande, sits at almost 3000m! As such, even in 1940 malaria in Quito would not have been a problem. However, there may still be a small number of reported cases even at such altitudes each year – this is due to people who get infected with malaria from mosquito bites at lower altitudes, such as in much of the rainforest and coastal regions of Ecuador, and then travel back up to the highlands before the first symptoms appear, which can be as long as two weeks after exposure to the parasite.

As mentioned briefly above, although Quito, Guayaquil, the central highlands and the Galapagos Islands are considered areas with low to no malaria transmission, travellers to or residents in other parts of Ecuador should take precautions against getting bitten by mosquitoes, such as long-sleeved clothing in the evenings and sleeping under an insecticide-treated bednet at night. They might also consider taking preventative medication, also known as prophylaxis, against malaria. As this can be expensive long-term, this is usually only used by travellers rather than residents in malarial regions. There are several different types of medication that can be taken; since chloroquine resistant types of malaria are known to occur in Ecuador, Lariam, doxycyline and Malarone are the main types of prophylaxis recommended for this country.
