Recently at an outdoor coffee shop, I met my old friend James in person for the first time since the pandemic began. Over the pandemic on Zoom, he looked just fine, but in 3D there was no hiding how much weight he’d gained. As we sat down with our cappuccinos, I didn’t say a thing, but the first words out of his mouth were: “Yes, yes, I’m now 20lb too heavy and in pathetic shape. I need to diet and exercise, but I don’t want to talk about it!”

When you think about what separates humans from chimpanzees and other apes, you might think of our big brains, or the fact that we get around on two legs rather than four. But we have another distinguishing feature: water efficiency.

That's the take-home of a new study that, for the first time, measures precisely how much water humans lose and replace each day compared with our closest living animal relatives.

WHO is working with countries and partners to improve global vaccination coverage, through the “Global Vaccine Action Plan 2011-2020”. Through the plan, WHO:

Many of the causes of overweight and obesity are preventable and reversable. However, no country has yet to reverse the growth of this epidemic. Although other factors are involved, the fundamental cause of obesity is an imbalance of calories consumed and calories expended. As global diets have changed in recent decades, there has been an increase in the consumption of energy-dense foods high in fat and free sugars. There has also been a decrease in physical activity due to the changing nature of many types of work, more access to transportation and increased urbanization.

Protection against mosquito bites during the day and early evening is a key measure to prevent Zika virus infection. Special attention should be given to prevention of mosquito bites among pregnant women, women of reproductive age, and young children.

An infodemic is too much information including false or misleading information in digital and physical environments during a disease outbreak. It causes confusion and risk-taking behaviors that can harm health. It also leads to mistrust in health authorities and undermines the public health response. An infodemic can intensify or lengthen outbreaks when people are unsure about what they need to do to protect their health and the health of people around them. With growing digitization – an expansion of social media and internet use – information can spread more rapidly.

Member States have recognized the importance and need of an infodemic response through recent resolutions, coming together in solidarity and responding to calls for actions. Therefore, WHO is building partnerships across all societies to respond to the COVID-19 infodemic and is developing country tools for infodemic management that can be used now and for future infodemics.

WHO is working with partners across society to strengthen the scientific discipline of infodemiology. The purpose is to build and deliver sustainable tools that health authorities and communities can use to prevent and overcome the harmful impacts caused by infodemics.

Through partnerships, WHO works to bolster digital capabilities and leverage social inoculation principles to foster higher digital and health literacy, build resilience to misinformation, and deliver innovative ways to reach communities with reliable health information. Here are a few of those innovations:

Overweight and obesity are major risk factors for a number of chronic diseases, including cardiovascular diseases such as heart disease and stroke, which are the leading causes of death worldwide. Being overweight can also lead to diabetes and its associated conditions, including blindness, limb amputations, and the need for dialysis. Rates of diabetes have quadrupled since around the world since 1980. Carrying excess weight can lead to musculoskeletal disorders including osteoarthritis.

Human immunodeficiency virus (HIV) is an infection that attacks the body’s immune system, specifically the white blood cells called CD4 cells. HIV destroys these CD4 cells, weakening a person’s immunity against infections such as tuberculosis and some cancers.

WHO recommends that every person who may be at risk of HIV should access testing. People diagnosed with HIV should be offered and linked to antiretroviral treatment as soon as possible following diagnosis. If taken consistently, this treatment also prevents HIV transmission to others.

Safe and effective vaccines are available to prevent hepatitis B virus (HBV). This vaccine also prevents the development of hepatitis D virus (HDV) and given at birth strongly reduces transmission risk from mother to child. Chronic hepatitis B infection can be treated with antiviral agents. Treatment can slow the progression of cirrhosis, reduce incidence of liver cancer and improve long term survival. Only a proportion of people with chronic hepatitis B infection will require treatment.

Chemicals are part of our daily life. All living and inanimate matter is made up of chemicals and virtually every manufactured product involves the use of chemicals. Many chemicals can, when properly used, significantly contribute to the improvement of our quality of life, health and well-being. But other chemicals are highly hazardous and can negatively affect our health and environment when improperly managed. 

There is no specific antiviral drug treatment for chikungunya and there is no commercial chikungunya vaccine. Treatment is directed primarily at relieving the symptoms, including joint pain. This is largely achieved by using anti-pyretic drugs to reduce fever, by optimising the use of pain medication and by administering fluids. Aspirin and other non-steroidal anti-inflammatory drugs should not be administered until dengue can be ruled out in order to reduce the risk of bleeding.
