Arenaviruses are a type of small virus commonly found in rodents. When a person becomes infected with an arenavirus, symptoms usually begin within 10 days.
West Nile virus is a mosquito-borne flavivirus that is maintained in an enzootic cycle between mosquitoes and birds. Humans and horses are incidental dead-end hosts.
Meningococcal disease is caused by Neisseria meningitidis, a bacterium with human carriers as the only reservoir. It is carried in the nose, where it can remain for long periods without producing symptoms.
Despite good access to effective antibiotics, Streptococcus pneumoniae (pneumococci) is still a major cause of disease and death in both developing and developed countries. Pneumococci are the main cause of bacterial respiratory tract infections, such as pneumonia, middle ear infection, and sinusitis, in all age groups.
Hantaviruses are rodent-borne viruses. They may cause severe diseases with potential risks of human-to-human transmission via body fluids or droplets. Eliminating or minimising contact with rodents is the best way to prevent infection.
Hantaviruses are rodent-borne viruses can be transmitted to humans by contact with faeces/urine from infected rodents or with dust containing infective particles. They may cause severe diseases. Eliminating contact with rodents is the best way to prevent infection.
The transmission of Clostridioides difficile can be patient-to-patient, via contaminated hands of healthcare workers or by environmental contamination.
West Nile virus (WNV) infection is a mosquito-borne zoonosis. The virus is transmitted among birds via the bite of infected mosquitoes and incidentally humans and other mammals may become infected.
