Winter Brings New Viruses
As winter approaches, the World Health Organization is recording a gradual rise in influenza activity, while COVID-19 remains at low levels globally despite local increases. In European surveillance systems, about 11% of COVID-19 tests were positive, compared with 5% of influenza tests. Meanwhile, respiratory infection-related intensive care admissions in Saudi Arabia rose by about 30% over three weeks in early October. The symptoms of influenza, COVID-19 and respiratory syncytial virus (RSV) overlap, so symptoms alone may not be enough to tell them apart; testing may be needed, particularly to determine treatment for people at risk of complications. Current indicators do not point to a new global wave of COVID-19, but the virus can still cause severe illness, especially in older adults, infants, and people with chronic conditions or weakened immune systems. Experts recommend getting the appropriate vaccinations, ensuring good ventilation, washing hands, and avoiding contact with others when ill. Seek urgent medical care for difficulty breathing, chest pain or worsening symptoms.
