There is currently no licensed vaccine for Lassa fever, but several potential vaccines are in development. Despite not being licensed as a treatment for Lassa fever the antiviral drug ribavirin has been used in several countries as a therapeutic agent. However, there is still a need for a safe treatment with proven efficacy, and a range of potential treatments including immune therapies and drug therapies are currently being evaluated. No evidence supports the role of ribavirin as a treatment for Lassa fever. 

The incubation period of Lassa fever ranges from 2–21 days. The onset, when it is symptomatic, is usually gradual, starting with fever, general weakness and malaise. After a few days, headache, sore throat, muscle pain, chest pain, nausea, vomiting, diarrhoea, cough, and abdominal pain may follow. In severe cases facial swelling, fluid in the lung cavity, bleeding from the mouth, nose, vagina or gastrointestinal tract and low blood pressure may develop. 

Landslides can cause high mortality and injuries from rapidly flowing water and debris. The most common cause of death in a landslide is trauma or suffocation by entrapment.

Broken power, water, gas or sewage pipes can also result in injury or illness in the population affected, such as water-borne diseases, electrocution or lacerations from falling debris. People affected by landslides can also have short- and long-term mental health effects due to loss of family, property, livestock or crops.

Meningitis is a serious infection of the meninges, the membranes covering the brain and spinal cord. It is a devastating disease and remains a major public health challenge. The disease can be caused by many different pathogens including bacteria, fungi or viruses, but the highest global burden is seen with bacterial meningitis.

Equal access and the reliable supply of medicines is an ongoing goal of WHO and global health delivery systems, the achievement of which is hampered by several factors. The first is regulatory issues, which can affect how medicines are bought to market, create lag times and cause the supply of medicines in some areas of the globe to be delayed long after they are available elsewhere. High prices, misuse of drugs and poor or unreliable drug quality contribute to this issue.

The first synthetic pharmaceutical, Aspirin, was introduced in 1897. Since then there have been incredible advances in drugs for a wide range of health concerns including disease, mental health and other conditions. Today there are thousands of drugs on the market able to prevent, treat and lessen the impact of ailments that would have been fatal just a few generations ago. At the same time, antimicrobial resistance is challenging the effectiveness of many commonly used medicines in one of the most concerning threats to global health today.

Policies, strategies, and action plans for health technologies, specifically for medical devices, are required in any national health plan. Within the context of a robust health system they ensure access to safe, effective, and high-quality medical devices that prevent, diagnose, and treat disease and injury, and assist patients in their rehabilitation.

Marburg virus disease is a highly virulent disease that causes haemorrhagic fever, with a fatality ratio of up to 88%. It is in the same family as the virus that causes Ebola virus disease. Two large outbreaks that occurred simultaneously in Marburg and Frankfurt in Germany, and in Belgrade, Serbia, in 1967, led to the initial recognition of the disease. The outbreak was associated with laboratory work using African green monkeys (Cercopithecus aethiops) imported from Uganda.

Malaria is a preventable and treatable disease. Early diagnosis and treatment of malaria reduces disease and prevents deaths, and also contributes to reducing transmission. The best available treatment, particularly for Plasmodium falciparum malaria, is artemisinin-based combination therapy (ACT). Antimalarial medicines can also be used to prevent malaria. 

Malaria is an acute febrile illness. In a non-immune individual, symptoms usually appear 10–15 days after the infective mosquito bite. The first symptoms – fever, headache, and chills – may be mild and difficult to recognize as malaria. If not treated within 24 hours, Plasmodium falciparum malaria can progress to severe illness, and lead to death.

Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable. There are 5 parasite species that cause malaria in humans, and 2 of these species – Plasmodium falciparum and Plasmodium vivax – pose the greatest threat. 

In response to the urgent need to address physical inactivity levels worldwide, WHO developed the Global action plan on physical activity 2018–2030 (GAPPA): more active people for a healthier world, and supports countries and stakeholders to implement these actions across the four key areas;

Physical inactivity is one of the leading risk factors for noncommunicable diseases (NCD) and death worldwide.  It increases the risk of cancer, heart disease, stroke and diabetes by 20–30%. It is estimated that four to five million deaths per year could be averted if the global population was more active.

Patient safety in health care is an urgent and serious global public health concern. Patient harm exerts a very high burden on all health care systems across the world. Every year, an inadmissible number of patients suffer injuries or die because of unsafe and poor quality health care. Most of these injuries are avoidable. The burden of unsafe care broadly highlights the magnitude and scale of the problem. 

Palliative care is a crucial part of integrated, people-centred health services (IPCHS). Nothing is more people-centred than relieving their suffering, be it physical, psychological, social, or spiritual. Thus, whether the cause of suffering is cancer or major organ failure, drug-resistant tuberculosis or severe burns, end-stage chronic illness or acute trauma, extreme birth prematurity or extreme frailty of old age, palliative care may be needed and integrated at all levels of care.
