The World Health Organisation (WHO) has released the list of pathogens that could trigger the next pandemic.
The number of pathogens has grown to more than 30.
More than 200 scientists spent some two years evaluating evidence on 1,652 pathogen species mostly viruses, and some bacteria to decide which ones to include on the list.
The new list of pathogens includes influenza A virus, dengue virus and monkeypox virus.
It also has several strains of influenza A viruses, including subtype H5, which has recently caused an outbreak in cattle in the United States.
Five new bacterial strains have been added, responsible for diseases such as cholera, plague, dysentery, diarrhea, and pneumonia.
Nipah virus, cases of which have been found in India recently, is also there on the list.
