Respiratory illness season in the US: Key tips to stay healthy and boost immunity

Respiratory illness season in the US is here and the spike in cases of Influenza, Covid-19 and RSV could trigger health concerns, especially among children who are more susceptible to the viruses as compared to adults. Older adults and people with weakened immune systems also remain at higher risk. As per US Centers for Disease Control and Prevention, flu season could be similar or better than last year. However the hospitalisations could still be well above the typical years before Covid-19 pandemic.

Current status or respiratory illness spread in US

As per CDC, Covid-19 activity remains low in most areas but may see an uptick in the coming weeks. Seasonal influenza activity remains low nationally but continues to increase slowly. RSV activity is moderate and continues to increase in most areas of the United States, particularly in young children. Respiratory infections caused by the bacterium Mycoplasma pneumoniae remain elevated among young children in the United States.
RSV is one of the common causes of severe illness that requires hospitalisation in children under 1. It is estimated that 2-3 out of every 100 babies in the US with RSV infection are hospitalised. The babies may need oxygen to help with breathing or (intravenous) IV fluids if they are not eating or drinking. Most of these children get better and can go home after a few days.
Vaccination coverage with influenza and Covid-19 vaccines are low among US adults and children while those with RSV vaccines remain low among US adults. Many children and adults lack protection from respiratory virus infections afforded by vaccines, as per CDC.

Vaccines remain the most effective way to prevent severe outcomes. Experts recommend getting flu shots, Covid-19 boosters, and RSV vaccines (for eligible groups). These vaccines can often be administered together, though they can also be spaced out for convenience
