Newborn deaths account for 47% of deaths among children under the age of five globally, resulting in 2.4 million lives lost each year. About one third of newborn deaths occur on the day of birth and close to three quarters occur within the first week of life. In addition, almost 2 million babies born with no signs of life at 28 weeks of pregnancy or more (stillbirths) and 295,000 maternal deaths occur each year.

Reducing global malnutrition begins with a proper diet during pregnancy and correct breastfeeding of infants. WHO recommends breastfeeding babies exclusively for six months, with safe and complementary foods being added slowly until age two or beyond. This means babies should receive only breastmilk from the mother or wet nurse with no other liquids or solids, including water unless required (such as oral rehydration solutions or vitamin and mineral supplements).

Proper infant nutrition is fundamental to a child’s continued health, from birth through adulthood. Correct feeding in the first three years of life is particularly important due to its role in lowering morbidity and mortality, reducing the risk of chronic disease throughout their life span, and promoting regular mental and physical development.

Many people with hypertension do not notice symptoms and may be unaware there is a problem. Symptoms can include early morning headaches, nosebleeds, irregular heart rhythms, vision changes, and buzzing in the ears. More severe forms may exhibit fatigue, nausea, vomiting, confusion, anxiety, chest pain, and muscle tremors. If left untreated, hypertension can cause persistent chest pain (also called angina), heart attacks, heart failure, and an irregular heartbeat, which can lead to a sudden death.  

Hospitals complement and amplify the effectiveness of many other parts of the health system, providing continuous availability of services for acute and complex conditions. They concentrate scarce resources within well-planned referral networks to respond efficiently to population health needs. They are an essential element of Universal Health Coverage (UHC) and will be critical to meeting the Sustainable Development Goals (SDG).

Hepatitis is an inflammation of the liver that can cause a range of health problems and can be fatal. There are five main strains of the hepatitis virus, referred to as types A, B, C, D and E. While they all cause liver disease, they differ in important ways including modes of transmission, severity of the illness, geographical distribution and prevention methods. In particular, types B and C lead to chronic disease in hundreds of millions of people and, together, are the most common cause of liver cirrhosis, cancer and viral hepatitis-related deaths.

Health financing reforms cannot simply be imported from one country to another given the unique context of each country and its starting point in terms of health financing arrangements; the underlying causes of performance problems differ in each country and it is these causes which the reforms proposed in a health financing strategy must address.

Health threats due to earthquakes can vary according the magnitude of the earthquake, the nature of the built environment (such as poor housing or urban slums), and the secondary effects of the earthquake, like tsunamis or landslides. Earthquakes can have immediate and long-term impacts on health.

Immediate health impacts include:

trauma-related deaths and injuries from building collapse;
trauma-related deaths and injuries from the secondary effects of the earthquake, like drowning from tsunamis or burns from fires.
Medium-term health impacts include:

As the health cluster lead for global emergencies, WHO works with partners to mitigate, prepare and respond to earthquakes worldwide. This includes:

The incubation period, that is, the time interval from infection with the virus to onset of symptoms, is from 2 to 21 days. A person infected with Ebola cannot spread the disease until they develop symptoms.
