This map shows percentage of Infants that are exclusively breastfed for the first six months of life.

The World Health Organization (WHO) and the American Academy of Pediatrics (AAP) emphasize the value of breastfeeding for mothers as well as children. Both recommend exclusive breastfeeding for the first six months of life and then supplemented breastfeeding for at least one year and up to two years or more.

Unlike most things that sound too good to be true, the list of benefits from breastfeeding is so long (and growing) that this practice could qualify as a bonafide magic bullet for health and wellness.

Whether in a poor or rich country, studies show breastfeeding significantly reduces the risk in infants for respiratory tract infections, diarrhea, asthma, allergies, childhood leukemia, many other infectious diseases and, over the course of a lifetime, Type 1 diabetes or obesity.

According to the World Health Organization, breastfeeding is the best form of nutrition for infants during the first 6 months of life. The American Academy of Pediatrics notes that breastfeeding is also beneficial for mothers as it lowers their risk of breast and ovarian cancers, lessens postpartum bleeding and even helps them lose the extra weight acquired during pregnancy faster.

Beyond The Map: PEPFAR Dashboards

Since its inception in 2003, the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) has received strong bipartisan support in Congress and through administrations, including two reauthorizations with significant majorities. The United States is unquestionably the world’s leader in responding to the global HIV/AIDS crisis.

Working in over 50 countries, PEPFAR has transformed the global HIV/AIDS response. PEPFAR supports more than 14 million people with lifesaving antiretroviral treatment. This is compared with the only 50,000 people who were on treatment in sub-Saharan Africa when PEPFAR began.

For the first time, the latest PEPFAR data also show significant declines in new HIV diagnoses among adolescent girls and young women. In the 10 African countries (63 districts) implementing PEPFAR’s pioneering DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored, and Safe) public-private partnership, the majority (65 percent) of the highest-HIV-burden communities or districts achieved greater than a 25-40 percent decline in new HIV diagnoses among young women. ‎Importantly, new diagnoses declined in nearly all DREAMS intervention districts.

With PEPFAR support, more than 2.2 million babies have been born HIV-free to pregnant women living with HIV and their mothers have been kept healthy and alive to protect and nurture them. PEPFAR also provides assistance to more than 6.4 million orphans, vulnerable children, and their caregivers.

PEPFAR continues to expand its impact by using data to drive accountability, find efficiencies, increase transparency, and leverage partnerships, including with the private sector. These efforts have made PEPFAR a model for development programs everywhere.

Map & Data: Malaria Atlas Project (@MalariaAtlas) of University of Oxford (@UniofOxford)


Beyond The Map: Country Profiles of malaria-endemic countries


The Malaria Atlas Project (MAP) brings together a global network of researchers with expertise in a wide range of disciplines, from public health to mathematics, geography, and epidemiology. We work together to assemble global databases on malaria risk and intervention coverage and develop innovative analysis methods that use those data to address critical questions. These include better understanding the global landscape of malaria risk, how this is changing, and the impact of malaria interventions. By evaluating burden, trends, and impact at fine geographical scale we support informed decision making for malaria control at international, regional and national scales.

As part of this mission, MAP obtains, curates, and shares a wide variety of malariometric data. These include malaria cases reported by surveillance systems, nationally representative cross-sectional surveys of parasite rate, and satellite imagery capturing global environmental conditions that influence malaria transmission. The MAP group provides the outputs of our research, as well as broader technical advice and support, to National Malaria Control Programmes (NMCPs), non-governmental organisations (NGOs), Ministries of Health, and other third parties as part of our commitment to open access data.

MAP is led by Professor Peter Gething of The Big Data Institute at The University of Oxford. The MAP group comprises research staff conducting academic work and technical staff who deal with obtaining, curating, and disseminating data and providing mapping support to NGOs and NMCPs.

MAP is a World Health Organization (@WHO) Collaborating Centre.

The Malaria Atlas Project has received designation as a World Health Organization (WHO) Collaborating Centre in Geospatial Disease Modelling. This designation primarily recognises MAP’s contribution to supporting the modelling, monitoring and evaluation activities of the WHO Global Malaria Programme.

MAP collaborates with WHO on the estimation of malaria programme coverage and disease burden and projecting changes in malaria risk to 2040.

27 JUNE 2018: ESTIMATED potential range of aedes aegypti and aedes albopictus in the united states, 2017*


*These maps represent CDC’s best estimate of the potential range of Aedes aegypti and Ae. albopictus in the United States. Maps do not represent risk for spread of disease.

Map & Data: US Centers for Disease Control and Prevention (@CDCgov)

CDC has updated the estimated range maps for Ae. aegypti and Ae. albopictus mosquitoes by using a model that predicts possible geographic ranges for these mosquitoes in the contiguous United States. The model used county-level records, historical records, and suitable climate variables to predict the likelihood (very low, low, moderate, or high) that these mosquitoes could survive and reproduce if introduced to an area during the months when mosquitoes are locally active. These maps include areas where mosquitoes are or have been previously found. Maps do not  represent risk for spread of disease. Ae. aegypti mosquitoes are more likely than Ae. albopictus mosquitoes to spread viruses like Zika, dengue, chikungunya and other viruses.

These maps show

  • The estimated range maps have been updated using a predictive model that used county-level records, historical records, and suitable climate variables to predict the likelihood (very low, low, moderate, or high) that these mosquitoes could survive and reproduce if introduced to an area during the months when mosquitoes are locally active.

  • These maps show CDC’s best estimate of the potential range of Ae. aegypti and Ae. albopictus in the contiguous United States.

  • These maps include areas where mosquitoes are or have been previously found.

  • Maps do not represent risk for spread of disease.

These maps DO NOT show

  • Likelihood that these mosquitoes will spread viruses. Shaded areas on the map do not necessarily mean that there are infected mosquitoes in that area.

  • Numbers of mosquitoes: These maps do not show how many mosquitoes are living in an area. Mosquito population numbers vary widely across the shaded areas on the map, from high numbers of mosquitoes in some parts of the contiguous United States to rare reports of mosquitoes further north.

  • Exact locations of mosquitoes: These maps are CDC’s best estimate of where mosquitoes could potentially live. Actual mosquito populations will vary by state and county. Mosquito populations may be found in an area that is not shaded on the maps and may not be found in all shaded areas.

  • CDC is not able to predict exactly how much Zika or other viruses spread by Ae. aegypti or Ae. albopictus could spread if and when local mosquito-borne transmission is detected.

27 JUNE 2018: lightning fatalities by state, united states, 2008-2017

SOURCE: National Weather Service (NWS)

Map & Data: National Weather Service (@NWS)

From 2006 through 2017, 376 people were struck and killed by lightning in the United States. Almost two thirds of the deaths occurred to people who had been enjoying outdoor leisure activities. The common belief that golfers are responsible for the greatest number of lightning deaths was shown to be a myth. During this 12-year period fishermen accounted for more than three times as many fatalities as golfers, while beach activities and camping each accounted for about twice as many deaths as golf. From 2006 to 2017, there were a total of 34 fishing deaths, 22 beach deaths, 19 camping deaths, and 17 boating deaths. Of the sports activities, soccer saw the greatest number of deaths with 12, as compared to golf with 10. Around the home, yard work (including mowing the lawn) accounted for 14 fatalities. For work-related activities, ranching/farming topped the list with 17 deaths.

Males accounted for 80% of all fatalities, and more than 90% of the deaths in the fishing, sports and work categories. Females had comparatively fewer deaths than men in every category, with their highest percentages in the boating-related activities (35%) and routine daily/weekly activities (34%).

June, July, and August are the peak months for lightning activity across the United States and the peak months for outdoor summer activities. As a result, more than 70% of the lightning deaths occurred in the months of June, July, and August, with Fridays, Saturdays, and Sundays having slightly more deaths than other days of the week.

Ages of the victims varied from young children to older adults with the greatest number of fatalities between the ages of 10 and 60. Within that age range, there was a relative minimum in deaths for people in their 30s, possibly due to parents of young children being less involved in vulnerable activities.

Based on the media reports of the fatal incidents, many victims were either headed to safety at the time of the fatal strike or were just steps away from safety. Continued efforts are needed to convince people to get inside a safe place before the lightning threat becomes significant. For many activities, situational awareness and proper planning are essential to safety.

Sickle cell disease (SCD) is a group of inherited disorders caused by mutations in HBB, which encodes haemoglobin subunit β. The incidence is estimated to be between 300,000 and 400,000 neonates globally each year, the majority in sub-Saharan Africa. Haemoglobin molecules that include mutant sickle β-globin subunits can polymerize; erythrocytes that contain mostly haemoglobin polymers assume a sickled form and are prone to haemolysis. Other pathophysiological mechanisms that contribute to the SCD phenotype are vaso-occlusion and activation of the immune system.

SCD is characterized by a remarkable phenotypic complexity. Common acute complications are acute pain events, acute chest syndrome and stroke; chronic complications (including chronic kidney disease) can damage all organs. Hydroxycarbamide, blood transfusions and haematopoietic stem cell transplantation can reduce the severity of the disease. Early diagnosis is crucial to improve survival, and universal newborn screening programmes have been implemented in some countries but are challenging in low-income, high-burden settings.

Between 1980 and 2014, there were 2 848 768 deaths due to substance use disorders and intentional injuries recorded in the United States. Mortality rates from alcohol use disorders (n = 256 432), drug use disorders (n = 542 501), self-harm (n = 1 289 086), and interpersonal violence (n = 760 749) varied widely among counties. Mortality rates decreased for alcohol use disorders, self-harm, and interpersonal violence at the national level between 1980 and 2014; however, over the same period, the percentage of counties in which mortality rates increased for these causes was 65.4% for alcohol use disorders, 74.6% for self-harm, and 6.6% for interpersonal violence. Mortality rates from drug use disorders increased nationally and in every county between 1980 and 2014, but the relative increase varied from 8.2% to 8369.7%. Relative and absolute geographic inequalities in mortality, as measured by comparing the 90th and 10th percentile among counties, decreased for alcohol use disorders and interpersonal violence but increased substantially for drug use disorders and self-harm between 1980 and 2014.
